Ok, so i recently bought a 2000 Mustang GT. The previous owner tried to use an aftermarket deck/head unit with the stock mach 460 stereo system. It wasn't working and CarToys informed me that you cannot use aftermarket decks with the stock stereo system without the difficult procedure of bypassing the amps. They reccomend to buy a used stock mach 460 head unit and everything should work fine. My question is, Do these head units have any security/anti-theft features on them that make it so they won't work if they aren't powered up for a certain amount of time? I have heard that this happens with many European cars but I'm not sure if it hold true with mustangs
