Hi, I have a 2012 Rangerover vogue 4.4 diesel. The media on off switch is flashing orange this causes the headunit screen to flash in a regular sequence and sound to drop out on all media inputs, after about a minute everything works as normal for about a minute then the sequence repeats itself. I have changed the Bluetooth module but can't guarantee that I bought a good one, but it is showing exactly the same fault, any ideas please. I don't have permission to upload a video, I'm guessing it's because I'm a new member, any advice would be appreciated
