How do I use this to activate maps on my Dell Axim X51 running Windows Mobile 5? I have the maps on a compact flash card (USA and Canada 865.3261 and UK and Ireland 865.3259) and the tomtom app (7) is on the main memory in program files/navigator and another folder just called tomtom in root. I have no idea how to activate the files and have tried everything I can think of.
