I just purchased a JL about a week ago. Still figuring it out. If I am using google maps on carplay, I can barely hear the voice turn by turn instructions. If the radio is on it is really difficult. The volume on my phone is all the way up. The voice commands sound like they are coming from the vehicle speakers. I recall this on a prior vehicle that had a garmin navigation. On that vehicle there was a way to increase the sound of the navigation voice instuctions. Anyone know how to up the volume for my google maps via carplay?
