What kit did you install on your coupe? My sister has the same, so quite curious. Thanks.
I got a nice unit from ebay - came in around £25. The sensors are a little smaller than the OEM Merc ones so I actually prefer these (rear only btw). I mounted the display on the trim that runs across the rear screen. You can see pics of it in my album:
I have sorted the gap in the trim out since taking this pic, it wasn't clipped in all the way when I took these.
