Hi I got my new AVH-P3200BT installed recently at best buy (big mistake). I ordered the ebrake bypass online and figured it would be an easy install to do myself. Except I can't figure out how to remove the mounting bracket around the headunit. Best buy refuses to give me any info on how to remove the headunit. I mean wtf is the point of having inputs on the back of a headunit if I can't take it out. Any help on how the hell to remove the mounting bracket for my car would be greatly appreciated.
