GPS suggestions, for use in truck and on bike?

[Todd T]

I rented a car on a work trip with the GPS unit... and it spoiled me. I'd really like to have something I can mount on the bike and then take to the truck. Better yet, something that could interface to my notebook computer for a larger screen. Heck, while we are at it... lets have voice commands, too!

Whats this I hear about photo maps? Are these photorealistic map programs?

Thanks in advance.
