Tom Tom

We just returned from a week in Key West. The weather was ok - warm and windy - not the best boating weather, but we did get out to Snipe Point for some wonderful swimming with the kids.

We rented a car from Hertz and had the onboard navigation (NeverLost by Magellan). Very cool. I'd never used a nav system and found it very useful. For the navigationally challenged (my wife) it's very nice to have. So I'm doing some research and considering a future birthday present. Has anyone out there had experience with after market in-car gps systems (not factory installed)?

I'm currently looking closely at Tom Tom and looking forward to their upcoming release on the TT 700. We'll see...
