The Underscore Archives

I'm going to dust off my PDA (Dell Axim x3) and turn it into a Sat Nav
thing as soon as I can find the right kit. There's quite a few
Bluetooth units that sit on the dash but was wondering if anyone has
already done this and has any recommendations?

TomTom seem to have the market cornered in the all-in-one world, but
I'm guessing it's just a piece of software, are there others that
might be better?

I will continue to Google but any personal recommendations/experiences
would be welcomed.

Cheers
