I just completed installing this in my 2017 following
@NKP Garage 's video. The cursor is obviously responding to whatever is going on in the OEM interface behind the CarPlay projection and so I disabled or minimized the clicks and feedback in the OEM menu. I don't know if the joystick signal interrupt (or whatever that cable is called) was supposed to change this.
I had a brief interrupt in the audio stream despite my phone being 1-2 inches from the wifi antenna I put underneath and to the right of the transmission shift plate.
I also noticed diminished sound quality and found there is an EQ menu in the module's interface so I set that back to flat and it seems better so far (did that at lunch today).
I'll never use it but the YouTube app works with my phone set as the wifi source. I was unable to get airplay to work on my first attempt.
I'll report back after I get the RCA video input wired to my trailer for rearview camera off its back.
Overall, I'm really pleased with how well it's working for the price.
