I have the silver, and added the front cam and CHMSL cam, I then switched to the lock pick both have the good and bad points. One thing I will tell you is the sweedes have a warped way of talking to people at least Magnus does, and I am not the only one to complain about this.
When I bought it he told me it would work fine without the back button at the time I did not have the 8.4 bezel installed. He lied it will not allow you to toggle thru the cams without the back button which I now have.
As far as the price goes for some crazy reason the prices you see before you actually create an account are not always correct. For instance when I bought the silver it was listed at 299.00 euro, it actually showed up in the cart at 179.00 euro.
Oh one other thing the harness they sent me arrived with a broken drawbar, they sent out a replacement right away and did not ask for the other one back.
And in fairness to Magnus with the back button issue he offered me a full refund.
As far as how it worked it worked as advertised, except hooking up the apple TV is not explained nor does it come with the required hardware. I later found that you need to use an AB switch and separate mirrorcast device which shares the video input with the chmsl cam.
Probably the thing I did not like about it was the front cam, it would come on every time I stopped and no way to change that. Seems they could have made it so it comes on when you start the truck, and goes out when the truck reaches a certain speed (which it does) and then not come back on unless you turn it on. Having it come on everytime you stop can be kind of annoying at least for me anyway.
