I have a 2005 LX470. I have been reading all of the stereo posts but am unclear on one item and do not see mention of it. I was thinking why can I not remove the tape deck and fabricate a plate and mount a new head unit there running new wires amps etc? Realizing that the factory amp wiring provides power to the head unit, am I going to run into a lot of issues with the tape deck unplugged like loosing the entire touch screen ac controls etc? I have already removed the cd changer and don't have any issues.
