W204 2009 Installing a reverse camera.
I recently purchase a 2009 W204 C200 Elegance, I think its EURO spec. The car is for my wife & child and I would like to install a reverse camera for safety reasons.
Done some research and I can replace the whole unit for an Android 8 inch system for about $850 but this is a bit of an overkill since my wife don't need the GPS and media player etc.
Ideally I want to add just a reverse camera to the standard screen.
A local dealer said I need a interface + camera for $500. Which seems a bit expensive for just a camera.
Below are screenshots of my unit.
No reverse camera option in the Engineering Mode.
Any advice or options?
