Can we get a sticky radio swap guide going? I think alot of us have similar questions about upgrading our stock radios with a newer stock radio that has an aux jack or dvd option. It seems using a stock radio unit keeps all the functions like the steering wheel controls and satellite radio etc. working as well as having a simple plug and play install. Post pics of the units or whatever ya got. Be sure to include all the details, year, make, model, satellite radio, pioneer system, aux input, dvd. Post up!
