HTC Touch: only muted calls with Becker Cascade navigation system

[baucis99]

Hi guys,

I have searched up and down this forum and other forums, some problems get close but none of them hits the spot.

I am using an HTC Touch with Windows Mobile 6 Professional, Version: CE OS 5.2.1238 (Build 17745.0.2.3) and link it via Bluetooth with the car navigation system Becker Cascade 7944.

The link is established but calls are muted. Becker had this problem with some other phone models too and brought out an update version 3.7.

Now the calls are not muted anymore, but the sound is distorted. It sounds like the loudspeaker is broken. In short: not usable.

I posted this problem with Becker and after the update version 3.7 they sent me this mail (translated from German):

Dear xxxxxxxxx,

the System-Software 3.7 was sent to a lot of customers as update. Only
positive results came from this and we did receive no negative replies or
complaints except for two models from HTC.

Please contact the manufacturer of the mobile device and ask for a
possible software update.


We regret we can’t give you any other answer.

Sincerely
i. A. Martin xxxxxx

Then I sent a fax to HTC Europe headquarters asking them for support and /or a solution. Nothing heard from them.

I then sent a fax with the HTC Europe headquarters fax attached to the Chairman of HTC (see www.htc.com) in Taiwan. Same result, no reply!

In the french forum www.planete-htc.com they have a post that the CAB-file WM6_BT_DUN.cab could solve the problem. I have not installed this file yet, since I don't know what it does or if it solves the problem.

Could it be that HTC uses a different bluetooth stack or CODEC-files?

Can anyone help me?

Thanks a lot

Hi!

I've got the same problem with an other phone from HTC (MDA Vario 3 from T-Mobile) and my Becker Cascade. Spoke with Becker, no solution in sight. They said I've to talk with the producer of my mobile ..... grrr.

Bye the way, if you make a call and after being connected with the other side you can press "private" in the options menu to give the call back to the phone. Then again press "private" in the options menu and you have a clear connection without distortion!

Bye, Peter (Germany)

PS: Tried the CAB-file, no change :(

hi @ all :-) I have the same problem with a becker Casscade pro and Firmware 3.61 and - now - 3.70.

This problems is only with HTC devices that have installed Windows mobile 6, (Wings, Kaiser, Touch..) with the older ones like T-Mobile Vario and Windows Mobile 5 it works fine.

by the way the same problem, the other side hear no sound from you, and you hear the other scrambled :-)

and it is not depend to use Sim access profile or normal earphone profile.

maybe i think, the Becker car radios are not longer supported from the manufactur..

the right way is, to change the bluetooth stack on the HTC devices. there are some parameters between mobile and bluetooth called EHR
and this parameters are wrong. maybe by HTC configuration or Becker :-)

A Nokia E61i and many other WM5 devices works well with Becker casscade pro.

i can try tomorrrow some AT&T Models with windows mobile 6 (Samsung and some other) maybe they works...

[joy.d]

soon, now i test a becker casscade with a samsung shg 6xx smartphone with WM6.
BT Profile works very well with casscade 3.70 firmware.
so it´s a problem of all actually HTC devices with WM6 i think.

maybe we should change the BT Stack was inatlled as default...

Hi joy.d,

I thought of the same solution.
I tried one of ROM cooking guys in this forum about how to change the BT software, but no reply.
Do you know how to change the BT stack on the HTC?

By the way I am using the HTC with the Jabra BT320s and the Plantronics Discovery 640X. Both work well.
And the Cascade worked and works with all other phones I know of. There is a forum in Germany for the Cascade and they report only problems with the HTC.
Also, some in this forum have reported BT problems with the HTC Touch.

So, please let me know if the BT software upgrade/change works.

Take care

hmm.. i have no time to cook my own rom with fixed bluetooth drivers. (maybe the actually bt version from broadcom, better knows as widcomm stack works well) we think in our company to change from htc to other manufactor, the bt problems not the only one problems ;-)

but if i found somethink i will tell you :-) please let me know if you find something.

p.s. the BT update for htc kaiser dont change or helps.

maybe becker has a problem with her integration of bluetooth.. with the most bluetooth headsets works the htc devices. (i test over 20 different BT Headsets with HTC devices, but the most with WM5)

I have the same problems. HTC Mobile 6 with Becker Cascade. To work around this issue, press [Private] in the [Options]Menu, once in a call, and then return back following the same keysequence.

According to the User Manual, Becker only supports the bluetooth HFP1.0 profile...

[joy.d]

Hmm, and the Windows Mobile 6 Devices supports:

A2DP (Advanced Audio Distribution Profile)
HFP1.0 (Hands-Free Profile)
HSP (Headset Profile)

It´s work with a Samsung blackjack, so i think the Problem is by the provided BT Stack from HTC..

[bitflip]

When the connection to the phone is made, a headset icon appears in the upper homescreen. It seems that the headsetprofile is initially used. When you execute the private workaround, the phone switches to handsfree...:confused:

[joy.d]

hmm, i tried it with this private funktion, but the quality of sound is not really good or better. is not a really funtional workaround. I have test the Becker cascade now with an Asus P750 Phone, and it works well too..

i think it is a HTC Problem.

[malix007]

Hi Guys
I am experiencing exactly the same problem with my HTC Kaiser and Becker Cascade Pro 7941. It really makes you upset when no one helps you, becker says its handset manufacturer's fault and HTC dont even bother to reply. :mad:

[joy.d]

yes, that´s sad. if you found a solutions let it know us, in germany, there are some more users with exactly same problem. :-(

Hi... not 100% related, but I have an HTC VOX and that works fine with the Becker High Speed Pro 7945 (same software as the Cascade) which I recently flashed to v3.6. The Becker works fine with 2 other HTC phones that I have, SP5 and SDA. The only difference is that the VOX actually displays the signal strength bars on the Becker bottom RH corner...

NOT all roses I am afraid as since I flashed my Becker, I lost ALL navigation functions.....:mad: but all other functions including the phone still work... :confused:

[joy.d]

hi fwd, but your Fox and the other devices is running with Windows mobile 5, right?
With WM5 all devices from HTC works fine with becker

Hi joy.d...

HTC VOX is a WM6 Standard (one of the first I believe)
SP5 is WM5
SDA is WM2003 Second Edition

[joy.d]

uhh, jey thats right, is a HTC S710 ? I try it the next time, if i have one from my users ;-)
Hmm... sad..

Yes joy.d, the VOX is the HTC S710... sorry should have mentioned that earlier - it is easier just to refer to it as the VOX :)

And the Cascade worked and works with all other phones I know of. There is a forum in Germany for the Cascade and they report only problems with the HTC.

Take care

Hi baucis99... are any of these forums in English, and if so, do you have the address ? need some info on transferring maps to cf card...

Thanks

Hey that's a good 'handle' !!! :D

FYI

I have the Becker Cascade and the HTC Herald (P4350) flashed with one of the cooked WM6.1 ROM's for the Herald.

I have the 3.5 software installed on the Becker and never had a problem whatsoever. The sound is clear, people can hear me perfectly etc.
My HTC shows that it has the "handsfree" BT profile enabled for my connection to the Cascade.

The only odd thing...
Because I am testing a lot of ROM's I frequently must reconnect the Herald to the Cascade.
First time connecting from the Cascade to Herald never works.
I need the Herald to look for the Becker and then everything works perfect.

[joy.d]

@fwd: ups :-) Sorry, i read snippi, at the last of your post Uhh, what for a mistake. ;-)
I say thank you again :-) unfortunately i have no experience with CF modding for the Becker. Only what i think about that is - that you can change the Maps to actually, is Navtec maps, maybe with a little xross comparing of actually navtec Maps you found the solution for newer map data. But i don´t use the casscade as navi, i like much more TOMTOM on my PDA. :-) The Becker is only my "online" drivers logbook and a excellent FM Receiver and Amplifier. I have build in in my car a PC (See the link above)

btw. Tell me what you want, maybe i can translate it to the german Board, but i think all people can speak (and read) english better than me. :-(

@Pong: hmm, the herald upgrade to WM6 is one of the first WM6 images. Maybe, there is a other (old) BT stack installed. But I remember, that the Becker (or some other WM6 PDA´s) lost sometimes the connection. (I set the becker to automaticly connect to headset Profile of.. xyz Profile) At the Moment i use the Firmware 3.71 from Becker, but I see nothing special, what is better than befor with 3.5 Software. Really sad, If my PC someday works perfectly, than i build the Becker to the luggage space for only one think to do: Drivers Logbook ;-)

maybe the time is over for 1DIN Navigation Units.. (but the becker cascade was one of the best devices in this market, with high well features, that some other 2DIN Device don´t have...

sadly.. or to sadden, maybe the time is over.. for thinks like this. I remember - as i was young i never can buy a Radio like this - it was always only a dream to have a becker - now i have one and the time for this is gone ;-)

[pong38]

@joy.d

Even with the stock Dutch WM5 ROM I had no problems connecting and exchanging services with my Becker Cascade 7944.

I don't think your "problem" is HTC ROM related.
Did you tried the steps for a first time connection as I descibed ?

[joy.d]

Hi Pong, yes, i use always the BT Headset Profile on my PDA. If I use a other device with WM6 (like Samsung Blackjack, Motorola Q9, Asus P750) all works fine. When I try a WM5 Device from HTC it works well too..

anyway: for my personal reason i dont´t use the cascade longer time as an free speech device. for me is it only for interesting, why and what - but i don´t use really the functions of my cascade pro - only fm receiver and amplifier. (and the most : he excellent drivers logbook what is needed for german self employes) :-(

I have installed a PC into my car, with all features and a lot more than becker, only one i needed: a stable drivers logbook for PC use ;-) (maybe i can try a WM6 logbook, and emulate it on my carpc) but it is really stable in this configuration ;-)

:-)

No problem joy.d, have posted on the Becker forum and looks like it is not possible :(

[comics69]

hi, i have the same problem with my htc diamond touch and my becker cascade....is there someone who solved the problem? i try all official rom and unofficial rom and rom radio for my htc, it's still the same thing....

i don't know is someone can help me....

thanks

[joy.d]

Hi Comic,

hmm.. I have the Becker Firmware 3.91 installed at my Becker Cascade Pro, same Problem, with Diamond, Touch pro, S740, Touch HD. It´s a Bluetooth (driver) problem. A Idea is, to porting a Widcom BT Stack to Windows Mobile if this possible (last devices that I see with a other BT Stack was with Windows Mobile 6 (HP, Fujitsu Siemens, and some other devices) or maybe it will help to compare the BT settings and drivers with a Device like Asus P750, where BT with cascade is working. Unfortunately I have not time for evaluating like this, my problem child is at the moment the stepmotherly HTC Shift device :-(

With a Nokia E71 -> Cascade all it works fine, I use a MultiSIM card, and 2 times Windows Email Push Services (on with Nokia and one with HTC Device) so I have always the same contact database online and this workaround fits ;-)

Not really happy about that, but now I´m become a new Job with this :-) "To force" the functionality of Nokia´s "Mail for Exchange" (MfE)Client. Maybe "sometimes" that´s a really alternative to bad developing of expensive HTC devices.

bg Joy

[comics69]

hi, thanks for your reply, but i'm a newbiz, and how do you want i change the diamond's bluetooth stack? or where i can find in the diamond its settings for BT? and can i use BT stack from an other pda or smartphone which work with WM6 and which work with my cascade? if you can tell me more about this issues.....

thanks a lot!

[joy.d]

Hi Comic, that´s the problem. It´s not easy for an beginner. You must modify the ROm (or Firmware) of your Diamond and that´s not easy like a PC/Notebook. Only really experts can do that. (You can ask into the Diamond thread) http://forum.xda-developers.com/forumdisplay.php?f=430 maybe there is somewhere who can change the Bluetooth stack to a other then default. I remember, that we do things like this with the first interesting devices like the wallaby http://forum.xda-developers.com/forumdisplay.php?f=268 but within the new Devices there are some other problems, so that the chance is very bad, but maybe try to post a message to the diamond ROm developeing thread, maybe someone have a solution.

If you found a solution please post it here, some other users of Becker Cascade will thank it to you. Unfortunately I have no time to develop that BT Issue again, since Windows CE 3.xx to Windows Mobile 6.1 much Issues in developing of WM devices has changed and now I´m self a Newbie with the new devices.

I hope you have luck, the Becker Cascade is one of the last "1DIN" Premium Car Entertainment Systems - it´s sad wehn some Users kick out the Becker about this malfunction..

Maybe a solution is the new Becker Firmware 4.xx, but I have not hear about some Becker User with 4.xx Firmware if it works with HTC Windows Mobile devices.

;-)

[comics69]

thanks for your information, i'll try to post a new threat, but can i try to modify the parameter in my htc? i downloaded an advanced configuration tool, and i can modify some parameter (stereo, spin,...)....do you think it could be work?

[joy.d]

Oh, there is a new tool?

Hmm, send a link to the tool please ;-) Maybe you can change parameters like packet size of BT packages?

[comics69]

i downloaded a rom on other website, and the tool was inside the rom, but i have no battery anymore, i can't tell you what rom is it right now, i let you know asap... i think the name of the tool is advanced settings, and you can have access to a lot of parameter in the diamond, such as BT parameter (stereo or not, frequency...)

[kc1]

Hi does fiddling with the AdvancedConfig tool BT settings work?

I have the same problem with my HTC Touch Pro & Becker Mexico....very annoying for a phone that cost £500 and a head unit that cost nearly twice as much !

[kc1]

I contacted Becker in Germany who suggested a firmware/software update to version 3.7 for my head unit (I am currently on 3.61), and have contacted the UK service centre to get hold of it.

Do any of you have 3.7 running?

[joy.d]

hmm, is there no newer firmware for the Becker? I think I have installed 3.71, maybe with the new maps there is a firmware 4.xx ?

[malix007]

Any news on this guyz ?????

[joy.d]

no, no other idea. maybe it works again with windows mobile 6.5?

what is the newest Software of cascade Becker pro at the moment?

I use at the moment a Iphone 3G OS3 + a Nokia E71 with my Becker. Works perfect :-)

[stefanlarson]

Hi,
have a TouchDiamond with most recent ROM, WinMobile 6.1. Becker Cascade 4.0 and distorted sound. Same mobile worked with my former Becker Indianapolis 6.0 and as alot of others have testified - other phones work with the Cascade 4.0

Have got some help from HTC but that hasn't worked yet. Tested JetWare which might do some tricks with BlueTooth, but not so. Changed HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Bluetooth \\SYS\\COD to be 5374476, no luck with that.

Have contacted Becker as well and they replied:

The identical problem is well-known to us from the model Samsung SGH-D900. This mobile phone supports only A2DP. A2DP is not supported by our systems. Our devices support excluding HFP (Hands Free Profiles) because A2DP is not necessary for acquitting. A2DP - Advanced audio distribution profile is meant for the transmission from audio signals in stereo quality in one direction to hear music.

HTC commented that Samsung SGH-D900 is quite old and doesn't even have Windows and that the TouchDiamond supports both A2DP as well as HFP. The very nice and helpfull guy I have been in contact with at HTC has limitations as to what he can say when it comes to hacks but does anyone think that disabling A2DP might work. Is so how to do that. I can see all the different profiles in the Registry, but then I need help.

[stefanlarson]

Just thought I would post this reply from Becker about the problem with Touch Diamond and the Cascade

"thank you for your inquiry.
After consulting our develope department we examine to adapte our system software to the peculiarities of these mobile phones described by you.

It is planned that the adjustments will flow into the Cascade SW 5,0. Currently this software is in the qualification. This software is available from Navteq approximately in Q3/2009"

So if we just fork out an extra EUR 150:- or so it will work :mad:
