Ordered a ProClip for a 2009 Mercedes GL Class. The installation guide says there should be stickers to keep it in place but they weren't in the packaging that I could see. Also the pictures on the web site show a space between the top buttons of the stereo's keypad, but that is not the case and some of the buttons are obscured though not so much that they are unusable. I'll probably still use the ProClip, but the experience is not as good as it was for the previous ProClip. Note that the delivery (acceptably) took some time due to the ProClip being manufactured on demand - mind you it was quicker than I expected considering.
