I had a similar problem installing Navigator 11 on a CE device memory card.
The installation went OK but when I put the card in my Actis 3 CE device it could not find Navigator.exe.
The advice given by Directions in the UK was:-
1. delete all on your sd card
2. insert it in your PC
3. start
installation of CE version and install it to mobilenavigator folder (you need
to create it first)
4. install map data, best if you create a folder for it,
e.g. data
5. rename navigator.exe (in mobilenavigator folder on SD) to
mobilenavigator.exe
Excellent support from Directions, this solution worked first time.
