My car is the second Acura I've owned with a nav system. It is basically a GPS, gyro, color screen, and DVD, integrated with the car. It is marvelous to never get lost. I don't bother with the coordinates.

I suppose there is a GPS in my cellphone. I have it turned off except for 911 calls, you can't disable GPS for 911 calls anyway.

The GPS systems that I am interested in have street maps associated with them although a handheld GPS such as those discussed here would be a fun toy!
