[W126 Coupe] GPS Recommendations?

[Dick Spellman]

Hi MBCoupes types:

I am ready to retire the XP laptop/usb to GPS solution I've been running 
for the past few months with Microsoft Streets & Maps.  Works well 
enough but, with the new laptop and Vista OS in hand I think it time to 
just put a GPS gadget on the dash or wherever.  I don't want to spend 
the $ for yet another docking station for the new laptop to sit in the car.

I am looking for a GPS that ideally mutes the Bluetooth radio/sat 
receiver when ready to announce an instruction and that's about it.  I 
use a Plantronics noise canceling earbud for the PPC (a Cingular 8525) 
so no need to duplicate the phone.  If there are any road warriors out 
there, what are you using or have you used and what's good or bad in the 
world of GPS?  Also, have any of you tried and liked PPC/Bluetooth to GPS?

I don't care about talking books or MP3s just need decent navigation 
with a mute command to the sat receiver so i can hear any instruction.  
The phone simply vibrates the earbud in my shirt pocket holder and 
that's simple and works.

I've seen some good and some really bad reviews of GPS so figured maybe 
someones got some experience and can chime in.  I've looked at the 
TomTom and Garmin lines from a 1/2 dozen websites including crutchfield, 
tigerdirect, tigergps, cnet and ebay.   I've read the reviews and remain 
confused.

Hoping for a few ideas.

Dick
