Hi all my first post on here and I am struggling to find the reason for a recent problem on my L322 2006 Vogue SE I have sound but only radio which is an untuned no signal sound all radio stations say preset 1 2 3 etc I do not have a flashing orange light its constant so doesn't indicate a break in the loop and I can only select 4x4 info and the on board with computer info screen but it doesn't give any real time stats and the venture cam screen with the touch screen I cannot select DVD , TV, CD, Aux and volume control on stereo will not turn the volume up or down but control on steering wheel works! When I put car in reverse rear cam doesn't engage now either. It's not the Bluetooth module or the Sat Nav or TMC as I have all these disconnected and bypassed via the correct bypass modules . I have checked all fuses and all are ok. I recently disconnect the battery a few times to install a new steering wheel could the issue be a software update for the infotainment system as the battery has been disconnected a few times. Cheers Jay
