Hahaha, yeah I lost my chimes too because of the amps. I really don't miss them too much to tell you the truth. Overall the android is way better than stock, but there is a few quirks that I wish they would address in future models. The radio app is trash, 5V or 6V pre-outs would be nice, rear video out (I think newer ones have this now), Bluetooth 4.0, and maybe a more customizable layout. And as far as losing the steering wheel controls, I got the PAC SWI-RC Steering Wheel Control Interface and got them back. I think there's a YouTube video on how to make it work with the Android unit.
