I doubt you can keep the rear control function with a new HU. The new HU would have to be capable of playing two sources at once for one thing.luvmyarmada said:Anybody got any ideas about retaining the rear a/v controls with an aftermarket head unit? I would like to replace my base system with something a little better. I don' t have a DVD but will be adding that too. Got all the info for that here.
