Dude, sorry and I don't meant to be disrespectful so don't take this the wrong way, but would you let go a good car for not having nav rather than getting an OK car for having nav? with all the aftermarket nav systems out there, even portable $500 ones that are the size of a palm pilot personally I would not let a good car at a good price go. You also have those papers with lines all over called maps, cheap and easy to use. Just my $0.02
