Information on automotive GPS / mobile mapping systems and notebook GPS software?

Use will be in USA and Canada.

I am looking for a mobile mapping system / GPS system for my mobile office (motorcoach). I have been thinking of possibly a GPS receiver to plug into my notebook and mapping software installed, but it seem it may be too clumsy to use while driving. Any recommendation on software and receiver?

If not that, who makes the better dash system mobile mapper with GPS? It needs to be accurate and have maps up to date, or at least upgradeable.

For my cars I use Caliber GPS P3600 for less than $300. It is pretty good and you can get map updates from their website. For my laptop I use DeLorme Street Atlas USA with GP20 USB plug ($135). They both work OK and even if you don't use your laptop as a GPS, it is a great map program to have on your computer.
