Garmin XT on WinCE 5 map install problem

Hello everybody,
I have one problem. When I installed Garmin XT to my device, put unlocked map to SD in mass storage and put *.unl file into directory "garmin" where is also map, I can not browse map in device. Only basemap is avaliable. When I renamed this map as basemap I can see regions in "about" but device shows no map.
How can I put maps to WinCE device?
Please give me some advices I tryed everything from tutorials here but nothing works.
For original Garmin device I have no problem but for WinCE device big problem.
Thank you for your advices...

You must tell us what map makes problems for you. Otherwise it's guessing game.

If the correct unlocked map with the name gmapprom.img or gmapsupp.img lies in Garmin directory (same folder like all other files and subdirectories) it normally works without problems.

Thank you for your answer.
I have map City navigator Europe 2012.3 in mapsource in computer unlocked and when I copy it by "mapsource transfer" to memory card it works on garmin machine.
But it is only gmapsupp.img without gmapprom.img. In Garmin directory lies also gmapbmap.img as basemap and I also tried to rename my copied map to this name but it was without effect. It shows me no map.
In "options" and "about" I saw regions of copied map.
I unlock map by "Unlock mapsource".
When I connect WinCE device I can operate only by active sync. Because of that I using memory card in other device - card reader.
Thank you for your answer.

In this case the 2GB limit of Mobile XT is the problem - try an image less than 2GB and it should be working.

hello no I selected only map of Slovakia (etc. 50 Mb). In my opinion problem is software "unlock mapsource"- is any different way how to unlock maps please?
Thx

The software can't be the problem - in most cases the problem sits in front of the computer :D.

There are two ways to unlock a map.

1. with JetMouse keygen http://www.navitotal.com/showthread.php?4195-Mapsource-tutorial-Unlock-Mapsource
   but for maps with FID > 2200 you need patched MapSource version http://www.navitotal.com/showthread.php?1100-MapSource-6.16.3-BaseCamp-3.2.2-TrainingCenter-3.6.3-amp-MapInstall-3.15.0-Patched
2. with MapSource Unlocker http://www.navitotal.com/showthread.php?2551-UnLock-MapSource-Directory-v2.2-(29.10.2011)

problem was place of program and map on storage

....now it works for me...
