Agreed. The NAV in a car is like a standard feature if you have a car with one.

I had a girlfriend (way back - when cars ran on steam) and she never had a car with A/C. She was shopping around for cars and I suggested she get the one WITH A/C (now, this is in So. Cal. too). She Hmmmd and Hahhd about it was a silly expense not worth spending because she lived without it before. But, she got the car with A/C.

She soon realized it after the first summer with the new car. She had her crow medium rare with a white whine.

I also have a portable NAV (Garmin iQue 3600) that i would take on business trips since I couldn't always get the Hertz cars. I'm still glad my own personal car has it built in. Never have to worry about chargers, cables, mounts, etc.
