If you can't get your phone book to sync with the device did you know you can create a contacts list on your PC then put it on the TomTom which will than work?
Its best if you can get your contacts off the phone on to the PC then edit each line of the text so it reads as follows:
"Tony Smith/M","0123456789","DEFAULT"
"Brian Smith/W","0123456789","DEFAULT"
"Brian Smith/H","0123456789","DEFAULT"
its "Name/Location","number","DEFAULT"
Location can be:
M = Mobile
W = Work
H = Home
When you have the text sorted out (Use NotePad on the PC to edit the text) simply save as "contacts.txt" (without the "") and transfer the file to the "contacts" folder on the TomTom - Mike
