I know you said it will work with any 8.4" screen. Did you mean any DODGE with an 8.4" screen? I was wondering would you know if it'd work with a 2019 Dodge Journey?
My issue is that there is no volume change past 25 while in the usb, Bluetooth is fine but usb once you get past 25 there's no change in volume even though numbers keep going up but not the sound. Almost as is it hit a limiter.
Having the same issue. Even with the windows down on the highway it turns the music all the way down while using CarPlay. Don’t have that issue while using Bluetooth. Which defeats the purpose because I would prefer the screen mirror feature.
