Fastball: You seem to have a lot of knowledge but as far as luxury car's heading into that direction, I dont believe so. For instance, the new Lexus IS. U can get it with or without the navi. Without the navi, its possible and done every day. That goes for a lot of other lexus models. Mercedes goes that same route as well. Beemer, depending on the model but like vtecvanos shows, its possible.
I believe the Honda wants us to buy their pss of shit radio products (mp3, dvd, etc.), thats why they went this route. YEAH RIGHT.

Where there is a will (and a more pissed off 03 Accord owner), there will be a way
