changing a radio wont mess up warranty...and if they say it does, fight it. the ONLY thing they could put the radio at fault for, is if something in the audio system/wiring went faulty. like with engines, if you put on an intake and you sling a rod, they can't just put the cause of that on your intake. they have to prove what caused it. It's not worth the legal fees for them to fight it, so they usually just let it go and replace the part (knowing thats what is supposed to happen anyways)
