Just bought a car that has a DEH-P840MP Pioneer Premier HU. NO BT or USB that I can find. The rest of the system is quite good. I would like to replace the HU with something that will fit in the mounting sleeve so I don't need to do a lot of rewiring.
Or is there some way to input my Andriod phone so I can play music. I am aware that I can get an FM adapter, but prefer to go hardwire. I can also use an iPhone.
