As I am a cheap baastid, and had one HP iPaq 220 and a Royaltec bluetooth GPS module lying around.
I hacked a TT software to the iPaq with Scandinavian maps. Voilį, works like a charm.
Have a set of ear phones, so that I can hear the voice assist inside helmet too.
Only thing is, the device is not waterproof.
Have tried to find a good soft casing for the device, with link arm to be attached to the bikes handle bar.
Ebay seem to have different casings, but not sure about the water proofing.
I could buy some of that magic stuff, what is promoted at Youtube. Nothing sticks to the treated surface.
