From the driver's point of view the camera is pretty well hidden. The front passenger has a good view of it though! :-) This is the second E Class I've had done and I'm not sure they are favourite cars for the Halfords guys. The power source is the fusebox in the boot so there is a lot of cable to run. Is the GLC the same? I used Halfords on Wellington Road.
That’s the problem I encountered hence installed the camera in the wife’s Audi where the mirror shroud is very small and camera can be tucked behind the mirror out of sight from both Driver and passenger (almost) whilst positioned in the Glc, the camera was “just there” blocking view
The Power supply in the Audi was piggybacked off the Power outlet sockets allbeit there is the option to take power from the fuse board and wire however I didn’t have the Audi connectors...
The power supply for the GLC, is in the side dash trim, this is the easiest option taking supply from fuse 216 glovebox light (5A),
It should (correctly) be taken from the fuse box in the boot, fuse 445 or 447 power outlet sockets (15A)
Full credit to Halfords for maintaining integrity & correctness.
Halfords, Wellington Road, is just down the road,
I was in there looking, noting the new Nextbases have integral mounts on the face plate, making the footprint smaller....
