|- Format your xl (make sure FAT only, not Fat 32) again,
- switch off then on again...
- reconnect and let tomtom put in its application (27mb).
- Switch off and switch on TT and connect again but don't use tt home...instead, find your map where you put it on the hard Drive and copy/paste onto tt xl using my computer and the drive letter your tt connects with ( may take a while to copy over but just let it run.
- Switch off, then on and connect using tt home this time and let it do its thing.
When finished you should be back to original factory settings.
Worked for me after messing around with my TT XL.
