Well, for the past few weeks I have been trying to work out how to get my TomTom ONE (v2) to talk to my Pocket Loox T830 - unsuccessfully.
Today I think I may have found out why; it seems Windows Mobile 5 AKU3 does not include a full Bluetooth DUN service - which the TomTom requires. Instead, they have added PAN (Personal Adhoc Network).
Bugger. I hope the guys at TomTom can get support for PAN connections soon ... Until then, I will have to resort to using the Traffic updates via my Nokia E61, which does work :(
