I have a ipod connection with my stock headunit and i was wondering if I installed a aftermarket headunit and connect the ipod to the aftermarket headunit?(if the aftermarket had a ipod connect) thanks for the input.

you cant use the stock connector with an aftermarket head unit. i'm trying to get engi to make me something to do that but i haven't talked to him about it in a while.

most radios with an ipod connection have a wire from the modulator to a junction, then your supposed to use a seperate wire from the junction to the ipod, this is even true with the OEM radio (except the modulator is built into the radio). simple fix, uninstall the stock modulator to junction wire, then remount the junction in the stock location. Looks clean, works good, Ive done this with jensens connections a few times and havnt had a problem yet. Just ask if ya want some pics

some pics would help me out. thanks.
