My experience with this is that I have previously installed a successful copy of version 1.0 on my Samsung Galaxy Tablet. The steps I did was the following:
0) downloaded the files, unrared them
1) uninstalled tomtom
2) insert tablet's microsd card into computer for speed
3) delete the map folder under tomtom
4) copy the downloaded and unrared map files into a temp directory (just easier to copy into tomtom later on instead of having to reinsert the microsd back and forth). Copy apk just to the root of card.
5) remove wifi connectivity on tablet
6) insert card back into tablet
7) install tomtom 1.3, and wifi enabled. Tried running it without map and getting cannot connect to tomtom and terminates.
move the map files in temp back to tomtom
9) Run tomtom again and works. This is with usacanada.
Going to try it on samsung phone later on - will update.
