saab stereos

i have a 99 9-5 i want to install an ipod im thinking of buying a whole new double deck unit. i was thinking of getting the navagation and everything. is there anyone who has suggestions of brands and models that work well. also i was considering just upgraqding saab stereos to a new saab stereos that would have navagation and an mp3 input. if anyone has any ideas if this is possible or not or any suggestions of brands let me know.

Just purchase an FM Modulator and play the iPod through that...cheaper, easier and sounds as good as the stereo it's played through. Wal*Mart has em, they plug into the lighter socket and have a standard stereo input.
