this is to get to the serial number if the factory radio so they dealer can look up the AntiThief code. I need a step by step DYI. I don't know which bolts/pins to remove..
I'm not tampering anything. I need to read the serial number off the back of the factory radio. Give it to the dealer and they will give me the anti-thief code.

I would think that any tampering with it may void the warranty so your best and only option would go back to the dealer and he may have it in your paperwork or at least do it safely and a lot faster!
