2k for GPS, consider this...

[PARAGON]

I have a Garmin GPS V with the car mount set up on the dash right over the steering wheel and about halfway between the windshield and the edge of the dash. I have it hardwired to the vehicle for the power only.

The GPS V has always done fine for me. I don't want a computer talking to me or need the color, and do take it out of the rig and use on my ATV as I have loaded both the street maps and topo maps and can easily switch back and forth. The only times I have problems with "reception" is in heavy tree cover or tunnels, etc. (the obvious places). I have yet to see the need for an external antenna.
