OK, so I have had TOMTOM NAV 5 software and I decided to add another region to my treo650, but it wont sync to my unit. I get an error message. I have not updated to 5.12 yet based upon what I've seen here.

Any thoughts on the sync problem to add this additional area to the SD card.

Would it be better to create a new folder and transfer directly to the card, rather than synching?
Any help would be appreciated.
