The LR3 Radio is known to have some reliability issues. The good news? The system isn't as complicated as most think. In this video, I attempt to properly diagnose my LR3 radio that was completely dead in the water...
Do you remember if the head unit was still flashing light out of the optical port? I have the same symptoms but the optical output is still flashing. everything else totally dead (head unit, screen, underseat dvd rom, rear entertainment etc)
The head unit controls everything on the MOST system. It’s likely your radio is indeed dead. The IR may work, but other parts of the radio may have failed. If you want me to pull my radio to check, LMK. Clearly I can disassemble this vehicle in like two minutes.
