Landrover DIscovery 3 no sound from headunit stereo Range Rover Sport LR3. FIXED.

When I purchased the Discovery 3 the headunit didnt play any sound, I was told it was intermittant, however I just never got it to work at all. After some investigation I found the problem and fixed it. I show you some tests I did along the way to help troubleshooting and finally show how I resolved the issue. If this video has helped you please consider buying me a coffee; https://www.buymeacoffee.com/trollman69b The headunit has been working perfectly for over a month now. This will be the same procedure for the Range Rover sport (2005 -2010) and LR3's.
