Great unit but…
Unit operates perfectly in my 2010 GLK350 with the NGT4.0 system. Installation instructions could use more clarity and should be reviewed by a fluent English speaker. The connector that joins the original car wiring is massive and fitting it in the dash with the original radio is nearly impossible. A better design would be to make the connector smaller and utilize zip ties to keep it in place. The radio is pushing quite a bit on the connector and I’m concerned about chafing of the wiring. The trim piece fits the dash nicely and the 10” screen looks like it came with the car from the factory. CarProKit needs to make a rear view camera that fits the car. In reality, it’s just a plastic molded trim piece that a universal camera could mount to.
