Garmin Mobile XT multiple map sets on a 6 GB card

---

Hello! I purchased a 6 GB card for my AT&T Tilt as I wanted to keep both CNNANT 2K8 and CNEurNT v9 readily at hand (as well as music, etc.) I travel to Europe regularly and didn't want to have to juggle data on a 2 GB card. Anyway, I installed Mobile XT on the card successfully and I'm using the latest versions of MapInstall and MapSource on my laptop running Vista. I have the map files unlocked and can display them on my laptop. I have keys generated for both map sets and pasted into both the .UNL files in the Garmin folder on the card. It appears as one continuous 75-character key in each file. However...when I attempt to install both map sets to the card, although the install appears to go normally, I can display only one or the other map set. I can see through Windows Explorer that the available space on the card is down to what it would be with both map sets installed. I go to 'Manage My Data' in XT and all I can see is one of the map sets -- Europe or North America. I have tried every trick I can think of to get both sets to install properly but there's no difference. I do notice that when both have been installed, Mobile XT takes an inordinately long time to initialize on my Tilt. Any ideas? Thanks for your help!

Warez discussion is not allowed on this board.
Anyway, contact Garmin if you want http://www.garmin.com/garmin/cms/sit...supportcontact

Wasn't discussing "warez," there...

Thanks for the reply. All I'm attempting to do is combine both map sets on one card. If Garmin tech support was worth contacting, I would have done it. I'm not pirating and not condoning those who do. The "keys" in question are only to facilitate letting me combine what's already mine in a format useful to me. These issues have been sufficiently beaten to death on other threads so let's not belabor the issue.

Sorry for the rant...

changing maps with mortscript

---

I was asking myself too if it's possible to use two different maps the same time.
But i don't think it's possible with the pda version from Garmin. Correct me if I'm wrong....

My workaround is a little mortscript i made to choose which map i want to use....
If you're interested i can send it to you, you only have to change the values etc...

It's quite possible to have more than 1 map in a card, but it's required some key generate to make it work because of the Garmin's brilliant ideal (locked map to its specified tiny 1GB-2GB card.)

if you want to have multiple maps for different areas on one card, you should use "gmaptool" to combine them and load the resulting .img file on your device.
You have to have the maps unlocked BEFORE combining them, everything als wont work.
Sadly you can`t use mapsource with the combined file without buying the programm "img2mapsource" wich could do the job.
I dont really need mapsource though.

You can even combine to maps of the smae area, for example to get autorouting in a topo map.
To do so, you have to unlock both maps, set the map prioority with gmaptool to show the topo map over the auto.routing map and combine them afterwards.

The program is used in the command line. Read the readme for further instructions.

There is another way... still manual though.

I use MapSource to transfer only the maps I need to my Tilt. Unfortunately, as you all probably know by now, Garmin Mobile XT does not allow more than one map on the card simultaneously. If you try to do it from MapSource, the new map overwrites the old map.

So what I do is create mapsets in MapSource and save them for quick recall.

I created a mapset for all of North America using City Navigator 8 maps. Then I transferred that to my Tilt. Next I went onto my Tilt's SD card and renamed the mapset with a "CN-" prefix.

Now, I went back into MapSource and created a mapset for the NW states of the US using my Topographic 2008 maps. Then I transferred that to my Tilt. Next, I went onto my Tilt's SD card and renamed the mapset with a "Topo-" prefix.

Depending upon which mapset I want to use (on road or off road), I just remove the prefix and launch Garmin Mobile XT.

It's a manual process to switch maps, but it's minimal work and they're always on the card where ever I go. I'm sure you could do the same with EU maps or other maps.

i think that's exactly what i am doing with my mortscript

I'm not sure if you're still looking for an answer on this or if you already figured out how to do this yet but I figured its worth a shot. I'm currently running Mobile XT on my Moto Q9h (WM6 device). The problem I was having was that if I loaded the detail maps for all of North America on to my 8gb sd card and then tried launching XT it would just hang on the splash screen at the beginning. After a bunch of reading and research I found a website that talked about loading different mapsets to XT (unfortunately I cant remember the website otherwise I'd give them the credit...). So what I ended up doing was breaking down my NA maps into 1 mapset for Canada and 1 for the US then I loaded both to my sd card and it worked like a charm. Here's what I did:

Install the first mapset to your device using Mapsource, so in your case I would imagine it would be the NA set but it can be either or. Once this is installed on your card, using active sync go to the Garmin folder on the storage card and rename the .img file from GMAPSUPP.img to GMAPSUP2.img. ** Notice that the name is still only 8 characters long **

Now that you've renamed that file, then go ahead and load the other mapset to ur device. Assuming that your maps are unlocked and good to go, you should see 2 img files on ur Garmin folder GMAPSUPP and GMAPSUP2. This should allow you to display both maps at the same time. You can verify the maps are installed by going to Tools--> Manage my data ---> Maps, it should display both sets plus ur base map.

Hope this helps.

This will work only if you copy two different maps, witch were unlocked with one and same map unlock code! If you have two different maps with two unlock codes - you should rename also GMAPSUP2.UNL file to have two working maps.
