What do you mean with cycling your Bluetooth connection Chris

If you go to Bluetooth Manager and turn it Off and then back On. For whatever reason, I find it jogs the memory of my Treo and it finds the TomTom GPS. I do this only if there is a problem initially.

It appears someone over at TC has been able to modify the TomTom 6 software to work with the Treo 680. Here are the details courtesy of Tom. I have not tried this, so modify at your own risk. People appear to be having success.

So here are five easy steps to follow and achieve what TomTom support probably wont get round to doing for another month or so :

1. Mount your SD card (via CardExport or similar) so that the files are available to you in Windows or Mac OS X.
2. Fire up your favourite hex editor. I recommend 0xED for the Mac (free) or HEdit for Windows (free).
3. Open "/tomtom/Munich.bin" from your SD card in the hex editor.
4. Goto offset 295D0C and find near there the bytes "rpsh201H", change to "mlaP350D".
5. Goto offset 2BBD1A and find near there the bytes "650", change to "680".

What I've done here is to change the Treo650 identifier to be the correct one for the Treo680, so understandably it will stop TTN6 from working on a 650, but then why go back to an older model now you have the shiny new one...
(You could easily pick another model identifier to update, for instance there are Zire's, 700p's and even the Treo600 listed, but it's left as an exercise for the reader to do that if they choose.)

Hope you enjoy,
Tom

Good news. Palm has released a TomTom 6 software update that includes official support for the Treo 680.
