RCA adapter for Symphony unit
 

I remember seeing an adapter for the symphony unit that would give you rca outputs from the stock head unit but i cant seem to find it anywhere. WOuld anyone know where i could find this adapter?

i've never seen or heard of this. you sure it wasn't just an aftermarket harness for retrofitting an aftermarket HU into the dash?

You can splice into your cd changer harness by loooking at the pinouts, but nothing is premade
