If i had 1000-1500 to use to buy a aftermarket Navi, i would either wait and save a few hundred more or try and make a better deal to get the stock Navi. In my opinion, nothing beats a stock installed Navi.
Well, all of that sounds good but we already own the car. Can they switch out our standard console for the nav version? Too bad I wasn't there when my wife bought the car maybe I could have convinced her to go with the nav version! But I can't complain having a frugal wife!
I'm sure you can get it done, but the bad thing now is that you may have to pay full retail for the navi plus installation. i heard the Garmin iQue 3600 was pretty good. Its a GPS palm PDA.
