Carplay audio issues: Aftermarket HU

I purchased a new aftermarket media player for a Jeep. (Ends in wood). I was having issues with the phone call feature of CarPlay. Mainly from no audio in speakers.

Solved: I had a stock amplifier, I did not have a aftermarket amp. The inputs were reversed I.e. the phone needs to be in the front input NOT the rear. The unit was installed correctly but the amp was reversed.

Had and the installer switch the inputs. Preso! Audio works phone works. Etc.

your audio fader control will will be backwards but it works.
