I think my stereo is a Bose system in my s3 but hasn't got any badges on the doors,the head unit is a concert item and says Bose when it turns on,the sub enclosure is a twin speaker one with Bose embossed on the enclosure and there is a Bose amp in the driver side of the boot,I've been told that the wiring harness to put a normal headunit in is quite expensive so I will look into getting my headunit repaired as its got the usual volume problem,I was just wondering if there is an adapter to plug in instead of the cd changer so I can use my iPhone for music instead
