I've purchased an AVH-P8400BH that should be here today and I'd like to test it inside my house before installing it into my car...
In the past I've used a computer power supply for the +5V, +12V, etc, so I could power the head unit and play around with it, etc. However, I obviously don't have a parking brake inside my house so how can I bypass this? I've heard a simple on/off switch works but how can I wire that?
