hey guys, just wondering what type of radio i would have OEM in the s3? it should be a double din. Currently got a symphony, but i suspect from a different car model, as it doesnt on/off with ignition, no gala signal, no speaker lf door panel. it also has a 6 cd in radio, whilst i got the 6cd in the boot. can't find really good information about this. are these problems just a small wiring issue that can be fixed, or should i be looking out for an oem radio?
