I have version 5 on my MiniS, with the TomTom bluetooth adapter.
I've heard it's a nightmare getting TomTom to authorise the move onto a new device so perhaps I'd be better selling TomTom with the handset on Ebay and putting the money towards the new version for the Diamond.
Well I got my Diamond (from Orange) today and busy setting everything up - first impressions good, although I think it will take some getting used to
Just posting a reply to this thread to say that TomTom Navigator 5 works fine, with the Diamond's built-in GPS (told TomTom it was on COM4).
Had no issues activating. I chose the manual activation option (automatic has never worked for me). This directs you to a website where you enter a code generated by the device, and the code from the card you originally received with TomTom. This generates a third code you tap in to TomTom and it all works fine - much faster than it ran on my old Vario.
This is the third device I've registered this copy of TomTom on (Axim X50V, then my Vario and now the Diamond) and its not grumbled. I read somewhere you just have wait 90 days between activating more than two devices.
I haven't yet been brave enough to install the TomTom updates to V5, because on my Vario (which was running WM6) I seem to remember that although TomTom 5.0 worked, the 5.x updates caused it to hang. However, if anyone has any better feedback on that, then it would be welcome.
