Mercedes-Benz Backup Camera Blue Screen
How to Troubleshoot Mercedes-Benz Backup Camera Blue Screen
Symptoms
- Blue screen
- No image when backing up
- Check that the entire surroundings show up but no camera image.
- Blue Screen – If the problem is intermittent and worse when it is cold, then it is likely that a faulty resistor inside the head unit causes this problem.
Suppose the backup camera has stopped working completely regardless of exterior temperature. In that case, the problem may not be the resistor inside the head unit but a damaged camera or wiring harness.
- Black Screen – If the screen is black, the problem can be due to a broken camera wire. The camera wire breaks at the trunk’s left (driver-side) hinge. Remove the panel and inspect the wire at this location for damage. Solder the wire if it is broken.
Solution
You must replace or repair the COMAND head unit to fix the resistor problem. The most expensive solution is to remove and replace the head unit with a new one. This method can cost between $800-$1200 at most Mercedes-Benz dealerships.
A less expensive solution ($350-$500) is to remove your old head unit and send it to a Mercedes-Benz specialist for repair. There are a few places that fix Mercedes-Benz command units, but you will need to ship them to them for repair. We could find W221 Comand Repair Service on eBay at the time of this listing. The turnaround time is typically between five to ten days.
