How much would a factory installed 2009 Nissan Altima radio be priced at?

I've been looking around for a good base car and have decided on the Nissan Altima. The only thing is, the base doesn't come with a radio. I'd like to get a radio from the dealership without upgrading from a 2.5 to a 2.5 S, so does anyone have any idea how much it would cost to have the radio installed on the new car at purchase?





Thanks :)|||To much go aftermarket you will get more bang for buck|||try to get the dealer to throw it in when u buy it or put it in the price
