Another Garmin Nuvi user. I forget which model, I've had it about two years. It announces the street names, but does not have traffic updates. I mount it to the right of the rear view mirror and never...repeat, never...leave it (or the mount) in the xB when I'm not in it.

Why would you leave your registration in the car?

For when you get pulled over for "exhibition of speed". :naughty:

Presently, . . .
Detailed map(s) and a vehicle compass (the ball kind on the windscreen)....

With any GPS you still need a map for the big picture. Ball compass on the windshield!!?? A-l-l-l-right! You must be one of my peeps!
