Hi all! i wanted to share my experience of installing aftermarket rear view camera interface for Mercedes Benz from CarsGadget that i did recently. It's fully OEM retrofit and has dynamic guidelines, just like the original camera does. Guidelines move as you move steering wheel. Also, it supposed to support OEM advanced parking system and show parking radar on the screen while in back up camera mode but GLK i installed the system doesn't have parking system so i just need to turn this option off. The reverse camera is sharp and activates quick once put into reverse. The interface unit also have the option to connect Front camera or MirrorLink to stream apps, video and audio from my phone which i am planning to install later. Anyways, here is the video with installation process i followed, let me know what you think:
