Well, here it is and in our forum a topic dedicated specifically to the Garmin Mobile XT 5.5.20wp dumped from a phone Garmin-Asus Nuvifone M20 and adapted to be compatible with Windows Mobile CE5 and CE 6.
[Only registered and activated users can see links. ].
The content put on an SD card.
The SD card should be named in the navigator SDMMC.
If it is not working - [Only registered and activated users can see links. ]. In this files there is a separate .exe file for different SD cards and for different versions of Windows.
There is also files for changing those in folder Garmin for navigators with 480x272.
Maps are put in folder System. Possible extentions are gmapsupp.img and gmapbmap.img (base map).
ID for the maps is 2222222222.
When you put the SD card in PC Mapsource will recognize it as Garmin-Asus M20.
The programm do not have a keyboard. Use the default one or additionally installed.
In folder Garmin there are two .exe mortscripts Run_CE5 and Run_CE6. Respectively for Win 5 and Win 6.
For WinCE 5 traditionaly needs to run the Explorer and set the GPS. There is no such thing in the script. For example in the file Reg.mscr in folder Garmin write the port of your GPS: RegWriteDWord(root,cKey,"ComPort",1)
On WinCE 6 the program run immediately and it will work without any additional actions.
Don't think this application can be compatible with Android OS as it is made for Windows Mobile. I remember there was , even you can find the dumped .apk from nuvifone A50 ,which is running Android 1.6, an attempt at xda-developers so the navigational application to be ported from the phone and be compatible with other phones running Android but no one has succeeded till now AFAIK.
Here is the original topic at xda if you are interested:
Do you know am I correct? I think M20 have different ROM version for different regions and therefore different versions of GMXT 5.52.xx preinstalled? I think this one, that I have posted, that is adapted in sosaw forum, is the Chinese version of GMXT 5.52 (version 5.52.20wp) but there is for example 5.52.10wp etc. with different functionality.
