I bought a used car two days ago and the fact it had navigation was a selling point that was listed and I expressed to the sales person as to why I wanted this car. The car was sold to me "as is" "no warranty", but when I got it home to test the navigation, I found that it would not accept the nav cd. Do I have any recourse with the wholsale lot where I bought the car, or am I hosed. I did finance the vehicle and am saddled w/ a $300 per month payment.
