I could be off on this, but for CarPlay to run audio through the vehicle, the truck has to have that mode selected. If on another mode, such as listening to Sirius, then the CarPlay app would be muted without a dedicated speaker.
Or is there a better way that Grom handles this scenario? If audio is from a CarPlay source then I agree it should be seamless.
