Thanks for the advice. I appreciate you taking the time to respond.

I'm interested because a friend has one is very happy with it -
especially for the money.
It also has PC tools that help him evaluate his flight, etc.
Neat!

The car aspect is also interesting since I live in the Balt/DC area,
and our in-car system has proved extrmely useful at twice the cost
of an aftermarket system (ha!).
