I will also say that if you live/travel in a congested area, try to get the
one with traffic alerts and avoidances.  My Garmin was 200.00 w/o traffic
and 320.00 w/traffice.  The traffic is picked up throught the DC charger. I
did not get the traffic upgrade(lifetime) cuz I'm a cheap skate(most folks
on the list know this :-)
BTW-My Garmin Nuvi 750 has FM transmitter and MP3 capability so I can upload
audio books and music and play thorugh the car stereo. Next time, and this
is important, I will look for a Blue tooth capable unit for hands-free phone
use.
