Try setting your device clock to 10 minutes before real time, and then start your GPS application to see if it helps.
There is a bug in the current release where the clock only gets reset when it is bedore correct GPS time.

i had similar problem and posted about this on previous page...
at random method i fix that by decrease "Lag Advance" parameter from 1500 to 150 (in both modes walking and driving)
ps: also try to disable any "Cell Tower service" and check for all "Prefer Gps" options is enable

I tried but it didnt do nothing! The problem wasnt solved. But thanks anyway
Ok today I will try that solution and will post the result later. Thanks in advance.
The versions screen is working here, did you soft reset after installing 3.6.0 when propmpted? Does your version info stay blank after you soft reset now?
Try re-downloading/re-installing the same cab again.
Update
3.6.2
- Fixed a bug where when loss of fix happens, the time to "keep fix" may have been incorrect.
- If device clock was in the past, it would never be reset to GPS time.
- Better detection of lost GPS input
- If allowing MSAPI, and COMx (both internal GPS, default config), and the current port looses GPS, ModDriver will switch to the other port. This recovers a stuck internal GPS on some devices.

maybe more reason to put this block
-----------------------------------------
Version 3.10 and newer: Added Direct support for reading cell tower location.
See the change log and Cell Tower features starting on post 1346 here
--------------------------------------------
on top! ...before "Newest Version:" block....
i'm not say... i told about "gpsModDriver_3_6_0_nologging.cab" - this version....
all other version show normal "about" page
ps: when i install new version on over old installer ask about "leave curent settings or use default - for default answer NO" (something like this) - i answer "NO" - but new version still has old settings...

Ok yesterday i tried and the problem still remains, but I notice some improvement. Can you explain me what the parameters "Speed threshold" and "Lag advance" mean/do?
Garmin with GPS Mod 3.6.2
Now with this version map screen in garmin shows position. Strange!
Now with this version map screen in garmin shows position. Strange!
"Lag advance" - thats how much distance add ahead if your position behind
"Speed threshold" - if your speed less than parameter "Lag advance" do not applies
THATS MY UNDERSTANDING
On my phone, Garmin draws a 'blank' map when ever I have too many things running, and it does not have many resources (ram, thread counts...) available. Eventually it does draw the map, but I usually just soft reset to free it up, and then Garmin acts normally.
I did not have other things running, when I use Garmin, because of topo map data it needs much ressources ;-)
But now I have another thing, where you could help me eventually: If I use GPS-Mod 3.6 with Default configuration, the gps position is not as exact as before. I have a software for gps tracking my bike routes, and now the track is often left and right away from the real route i drive.
Do you know, what could be the reason for that?

HD2 has a crappy GPS, not much I can do about it. It has been talked about here many times before.
I had thought about some kind of filter (averaging), but could never see anything that would work considering that you need a change in course to be recorded correctly.

Today I decided to deinstall GpsMod from WM HD2.
All my GPS applications (TomTom, Igo, Oziexplorer ...) started to change day time, gps coordinates unpredictably and crashed my device.
I did reinstallation several times, but unsuccessfully and it is a pity.
Had someone such situation?

5GPS Mod Driver (From original post in Diamond thread Ending Here)
This Driver installs between your gps application and the GPS driver that reads the hardware gps.
- Lag is compensated, by guessing your position 'some number' of milliseconds in the future, current course and speed changes are included in the guess.
- Driver corrects for invalid data in the gps strings, Out of range DOP values, and Heading values of 'NaN' (Not A Number). Position, Speed, and course are reported, even though the distance traveled is less than 30 meters.
- Cell Tower location is used when GPS is unavailable
- Altitude is corrected from/to WGS84/ASL
- Hardware Compass Support
- Allows selction of many input sources, including MSApi (GetPosition api)
- Suports GPS applications on any COM port, as well as GPSApi (GetPosition api)
Hardware Compass Support information is in Post Number two
QueStub support is in post Number Six, Garmin can now use GPS Intermediate Driver, so no longer needs QueStub
Newest Version:

External Card Storage
- If the card is removable, installing a device driver to it is just a BAD idea, don't do it!
- My attached shortcuts don't work, make your own or edit mine.
- Your card may not be avalable during early boot, so driver may not autoload.
- Driver will take londer to load, so phone will take longer to boot.
- ModSettings will take longer to load
- Uninstall is not as perfect, but still works fine, except it is possible that the dll on the card may not be removed if it is in use at the time.
- Did I say don't install to a card unless you have to?
- Install the driver cab, change your GPS application to the indicated port or to use Gps Intermediate Driver, instead of the original internal com port.
- Run GpsModSetup (found in start), you will see live gps data from the ModDriver on the main page. Tapping the screen will toggle to a sattelite view screen.
Menu/[Profile] (driving or Walking): to use a preset setup, Save will update driver to use new profile. If auto profile is enabled you will not be able to make this selection, but can still edit the profile's values.
Menu/System: to change the values used by ModDriver.
- Log File: Creates a debug log in \Mach2003 of the device.
- Extended: Adds more information to the logs.
- Track Log: Creates a GPX and CSV file to card\Mach2003 that can be viewed in Google Earth, or many other applications.
- Raw Data: Includes an extra GPX and CSV file for the raw input readings from the GPS source.
- Smooth: Allows Mod Driver to insert an extra GPS output at half the sleep time, so that some map displays are less jumpy.
GpsModDriver section
- Sleep Time: Amount of time that Mod Driver will wait for a new GPS reading. Default devices are 1000 ms.
- ComTimeOut: Passed on to the windows com driver when using a COM input port, amount of time readfile will wait for ANY data to arrive on the port.
- Keep Alive: Driver will keep reading raw data for this many milliseconds after the last reader port is closed. Allows for switching GPS applications without loosing fix.
Be very careful changing the following port, you may need a factory (HARD) reset if you change a port to one that is already in use!
- Com Port: The output port Mod Driver will use to send data to your GPS Application.
- Enable: Enable (or disable) All Mod Driver functions.
Internal GPS Device section
These settings are written to the internal GPS device registry, and MAY be used by the original driver
- Sleep Time: Time to Wait for data when no data is available ro read.
- Poll Rate: How often to check for new data from the internal driver.
- Input Buffer: Amount of phycical RAM to reserve for READING the internal GPS device.
- Output Buffer: Amount of RAM to reserve for communication to MS GPSID driver.
Be very careful changing the following port, you may need a factory (HARD) reset if you change a port to one that is already in use!
- Com Port: Com Port for GPSID data, same as using the 'External GPS' control panel 'software port' item.
- Enable: Enable (or disable) the internal GPS, same as "allow windows to manage device" under external GPS settings.
Menu/Extras: To configure additional settings.
Altitude Table section
- Altitude Fix, To enable driver to correct altitude to true (ASL)
- Prefer GPS, To use GPS altitude when avaiable instead of the table values
- Kill Feature Remove Table, Use to remove the altitude correction feature, and the table file from your card.
Auto Profile Selection
- Gsensor Angle, angle from vertical when to switch to/from walking profile.
- Enable portrait, To autoswitch profile when in portrait mode
- Enable landscape, To autoswitch profile when in landscape mode
Cell Tower Location
- Service is Running Now, Reports current service status, tap to update
- Enable Cell Service, ...
- Enable Service, Only with GPS, starts and stops cell service when Mod Driver is used/closed
- Enable Internet Cell Data, Allows Servicer to use data connection to resolve location of unknown cell towers
- Entries To Save, restricts the size of the cell tower database
- Default MCC, Can be set to YOUR Mobile Country Code for when your RIL does not have this vital information
- ReStart, Stop/Start Buttons.
- Export, To export known cell tower locations to a GPX file
- Update, Used to resolve all unknown cell tower locations, ignores Enable data Flag (use while connected through A/S)
- Kill Feature Remove Service, Use if you don't want cell tower location features.
Menu/Ports: To enable Mod Driver to use other input ports.
Port Scan Mode
- Scan On Power Only, default, allows scanning for a better input port only when the device is plugged in.
- Scan on Battery Too, allows port scan at all times, regardless if device is plugged in or not.
- Never Scan, disables the port scan feature.
- Scan Only Once, does an imediate scan, then sets itself to "never scan".
Input Port section
- Port (MSAPI, or Com Ports from 1 to 9)
- Enable, allows Mod Driver to read this port
- Fix, applies Mod Driver Lag, speed, and heading fixes to this port (some devices might not need these fixes)
- Order, Mod Driver tries to find GPS data on the Enabled ports in this order, 0 first, then 1, 2... (99) is auto entered for the "output" port, as it can not be used for input as well.
All screens have an 'Undo' and 'Save' button. Undo will revert all changes made to the screen, save will update the driver to use the new settings.
Profile Screens
- Name: Used for profile selection and display (alters the names on menu and selection screens)
- Set To Defaults button: Sets all profile fields to factory default values, as installed from the latest CAB.
To Insert Speed and Course section
- Distance Moved: Meters times 10 to update course and speed (30 = 3.0 meters)
- Zero Speed Time: Milliseconds to speed when distance above is not exceeded, your speed will "stick" until this time passes when not moving.
- Minimum Speed: Any speed below this value will be considered as "zero" to filter out erratic slow readings.
To Calcualte Lag Position section
- Speed Threshold: kph times 10 to update LagAdvance position (50 = 5.0 kph), readings with speeds below this value will not have lag applied.
- Lag Advance (ms): Number of milliseconds to project your position into the future to compensate for delay in GPS readings
Toggle Enable section
- Speed Fix: Allow the driver to correct speed
- Prefer GPS: If GPS raw data has a valid speed, use it instead of calcualting speed from position.
- Course Fix: Allow the driver to correct Course
- Prefer GPS: If GPS raw data had a valid course, use it instead of calculating course from position.
- Dop Fix: Allow the driver to correct bad dop values
- Compass: Allow hardware compass with this profile
Auto Input Selection
Mod Driver allows you to select more that one source port for reading GPS data. No matter what input port is used, your GPS application can read Mod Driver to get GPS data.
- You can enable Bluetooth GPS devices as well as MSAPI, and the internal COM port devices.
- 'Order' assigns the preferred port to use, 0 is the most prefered, 1 is next...
- When first started (any GPS application opens Mod Driver port), driver scans ports starting from 0, to find input data.
- If the scan mode is enabled, it tries lower order ports every 30 seconds or so, and switches 'up' to a better port if fixed data is there.
- If the current port looses connection, Driver will try any enabled port to get good data (regardless of scan mode).
- To install a BT device, pair it with your phone, and add an external com port to it.
Altitude Fix
The NMEA standard requires GPS altitude to contain Altitude above sea level (standard was made by boat people), and seperation from the WGS84 ellipsoid used in calculating the ASL. Sea level varies on the planet by up to +- 100 meters from the ellipsoid due to gravitational force changes. Using data from NGA (2008), a table was created (stored on CARD under \Mach2003, 64kb), and is used to determine the seperation value for the current GPS position. In testing, we found that the table value was more current (a more accurate value) then even the devices' driver was using. Prefer GPS will override the table value, and use what the device thinks is correct only if the GPS data actually has the seperation value. You CAN disable this feature and save a bit of card memory by deleting the Altitude*.RAW file. (if card memory can not be found, the file is retained in the devices \Windows folder).
There are also a couple of shortcuts attached here to auto-select a profile. You can copy them to start menu, or to app keys to assign to a hardware button. There is also a shortcut for running the "scan once" selection without "starting up" mod settings.
KillDriver.exe
Used to remove a stuck un-install of the driver instead of using SKTools.
Copy the un-zipped file to the device and run it. It will remove all the files, registry entries, plus the Mod Driver entry in the uninstall database.
It may leave behind some registry entries, and does leave behind the files under \Windows\App Install. You may delete these files manually after running the kill driver application.3GPS Mod Driver - Hardware Compass Support
Mod Driver supports the hardware compass on the HTC, and Samsung devices that have a hardware compass.
- Mod Driver uses Compass Heading below Delta Speed for the current profile in place of GPS heading.
- Compass speed is configurable, default is 2.5 kph (works with Garmin Mobile XT)
- Not all GPS applications will use the heading without a speed, your results will vary.
Samsung Devices need to have the SDK 2.0 cab installed (attached here).
When a hardware Comapass is detected an additional menu item is available for presetting the difference between the hardware compass and actual heading. This is required because your phone may be mounted slightly off angle, and it also reports a 'magnetic' heading instead of the GPS 'True' heading.
Compass hardware does NOT detect landscape rotation properly, but Mod Driver adjusts for this automatically.
Calibration factors are retained for each profile, so mounting (or holding) position is accounted for.
Hardware compass is quite useless in an automobile because of the huge amount of metal around you, and teh EMI that the car generates. You can disable the compass under "Driving" profile, and when using auto profile selection, the compass will only be used when you have the phone out of it's car cradle. Or if you don't use auto-profile, when you select walking profile.
The best way to calibrate the driver's compass value to to just edit the value directly, note that you can not enter a negitive value, but just add 360, and enter that (ie: -21 degrees = 339 degrees).
To calibrate the compass
Choose compass from the menu button.
Be prepared to exceed your current 'Delta Speed' Value for at least 10 seconds, and travel in a relatively straght path.
Compass Screen:
- Num Averages: The number of compass/g_sensor readings to average together
- Landscape Angle: For HTC only, the amount of rotation to determine that landscape is triggered.
- Poll Time: How often to read the sensors.
- The portrait and Landscape buttons are not selectable, but will show the current orientation of the device.
- Values for the current calibration from GPS to COmpass heading can be enetered manually, or viewed here.
- Reset to Zero, allows a simple reset function for each orientaion.
- Calibrate button enters self calibarate mode (see below)
- Help?, condensed version of this post
Calibration
There are three 'status' messages displayed. One for speed, averages, and overall status.
Each message has a check box that will tell you if that item has been satisfied.
Press Calibrate button,
Notice that count (at the bottom) will count down the number of seconds until you get to Delta Speed.
Once at speed, the count will change to teh number of readings included in the calibration average.
Compass and GPS heading are updated as messages arrive from the driver (about once a second).
Once 10 readings are taken for the average value, the updated value will be shown.3
Left the thread no way! I've been making test builds and letting RoryB do all the work of testing them (via email). He deserves a thanks for his hard work.3New Public beta build
I am now using a new build number version system for this project.
Currently Major version 3, will change with whole program update
Minor Version 3, will change if new features are added
Release Version 4, will change anytime I email or post an update
Build Version (various), each module has it's own counter.
Build numbers may not be the same on all apps/drivers in a cab (they don't all get built the same number of times).
Changes from 3.29 to 3.3.4
-Exiting COM input by testing good messages recieved
-Fixing altitude, whole new line of thought
My old routines were not updated when I changed from saving seperation value to saving AEL
No longer need to compare last reading to this reading to detect changing items
I am introducing a small error for some devices, when your actual seperation value is exactly 0.0
I will assume you have AEL in the data, when you actually have ASL and AEL, but they are equal
Driver will use its table, and alter ASL incorrectly, but table will be very close to zero, so the error will be very small
-Added version checking/logging for ALL related apps and drivers, including your GPS application itself
-Simplified ModSettings main page text (and font used)
Using off screen composting now
- Allowed restore backup settings on fresh install
- Detect loss of GPS data string, and switch ports (sudden BT power off)
- First "KeepFix time" of connection will use CellTower location, even when KeepFix is not enabled
- ReDo all the insert speed/heading, and keep fix logic
- Using KeepFix time for ALL cell tower insertion timeouts.
- rework portscan
- Changed scan allowance to get fix from 30 to 60 seconds
- Repair time difference calculation, messed up everything
- Reset GPS string time on first fixed position only
- Re-Work switch over to Cell/Unknown rules
- Clear GPS valid speed flag, and reset speed to zero as required
- Add short name to version screen/logging
- Menu, About, displays version info for all related aps and drivers, tap screen to close
For those that need the PPC2003 version of the driver, I have attached a beta version for you to try now as well.3Update
3.6.2
- Fixed a bug where when loss of fix happens, the time to "keep fix" may have been incorrect.
- If device clock was in the past, it would never be reset to GPS time.
- Better detection of lost GPS input
- If allowing MSAPI, and COMx (both internal GPS, default config), and the current port looses GPS, ModDriver will switch to the other port. This recovers a stuck internal GPS on some devices.
