I have researched and attempted all the tricks I could find on the net, to get the volume up when using Apple CarPlay and Maps. Siri is loud but the actual voice, with turn by turn instructions, is very low, even when set to the highest level of 11. I know it's not the phone, as I have tried the phone in two other vehicles, and it works fine, allowing me to adjust the volume to a level I can hear. My Honda however leaves much to be desired. Has anyone actually figured this out? No, no I don't need a hearing aid.
