I am less than 200 miles into my gx and I hate the nav system. I couldn't be more worthless...I have used a magellan 700m for some time and the 1000m (I think this is the right number) before that. This lexus nav system SUCKS! I thought it would be nice to get rid of the wires with this car and now I am a few thousand lighter in the wallet and I will still have the wires. And while I am bitching...how the heck am I supposed to get a dvd going for my 3 and 4 year old....
