Oy-vay...I searched and got a headache, sorry.....anyway, its an OEM type one radio, according to the owners manual. Got one from Ebay for a great price. Took the old whatever it was, out and ended up with two antenna type cords and three box plugs hard-wired into car harness. There is also a TATO JBL radio interface box and another plug and wires set. The car does have the premium sound system apparently. The only thing I can connect to the radio is the two antenna type plugs/cords and two of the hard-wired box plugs - no action from radio with this connection. Missing something; don't know what. Can anyone help me? Thanks.
