No audio on CarPlay

I installed the K smarter on my '17 SS, but I can’t get the audio to play through CarPlay. When I press play, it only plays through my phone. Any tips?

If it’s an Android, it might be a Bluetooth setting. For iPhone, I’m not sure—it could be an issue with a recent update. Have you updated to the latest firmware?

Connect your phone to the factory audio system using a USB cable and set it to iPod, or connect via Bluetooth and switch to Bluetooth, with the phone linked to the Ksmart wirelessly. CarPlay allows you to control the audio playback, but the sound still goes through the factory infotainment system. I prefer using USB since it charges my phone, and I find the Bluetooth audio quality in the SS noticeably worse than through USB.

Connect to Bluetooth and ensure that you switch the car’s audio to aux.

The 2017 model doesn’t have an AUX input.
