You do know that the OEM antenna is powered, don't you? I am not sure if it's powered by an aftermarket head unit without having to do something (like run a switched power wire to the antenna amplifier). Something like that. I still have an OEM head unit so it's not like I have personally had to deal with that. Possibly this is what Shiwnath was referring to.
