If you have obd11 then you should be able to code in your rear speakers. Need to go into the headunit settings and change the number of speakers and then do a hard reset on the stereoHiya @SamD and thanks for the offer. I’m up in Barrow most of the time. I’ll be heading to Wakefield on the 4th or 5th of august so will be going via your way and can call in if that’s convenient. I’ve managed to get the reversing camera working using my OBD11 but don’t know what to code for the rear speakers.
