I have a 2008 scion tc with the upgraded pioneer head unit. The one which plays mini graphics. I want to hook a system up to the car but im not sure if there are rca jacks behind the radio or even a remote wire. Does anyone have information on this.
Thanks

 

Ebay! they sell the adapter that plugs in directly to the back of the radio or have a system installer tap into the stock wires of the rear speakers. i had a guy do 2 tc's that way and a box that a friend bought the ebay kit and works just fine.

 

I believe this should still apply, worked for me:

Yes it does have RCA's (3sets) and for the remote wire, you just tap into the one coming out of the stock harness.

 

if you are talking about this radio, then yes they have RCA Jacks.

 

^ I believe it's orange.

 

^ the antenna control wire, that is.
