[time-nuts] GPS unit for car navigation -OT ??

[xaos]

Hello everyone,

I have, until now, resisted the urge to buy a GPS navigation system for 
my car.
However, I now have to do some traveling and new and unknown addresses
keep popping up.

There are several different GPS units on the market and they all look OK 
(i guess).

I just want to know which units do the members here consider to be the 
best for
this sort of thing?

Many thanks in advance,
