Kingston73 Posted May 23, 2017 Report Share Posted May 23, 2017 I'm upgrading from a pioneer 4400BT to a 4200NEX and currently have an aswc steering wheel control unit connected. I'm wondering if it will work without needing to reprogram it when I wire it into the 4200NEX harness? I already checked and the 2 do not have the same wiring harness so I'll need to disconnect the aswc and rewire it. Quote Link to post Share on other sites
