Unfortunately you have to turn up the volume on your phone and then your volume on the radio will suffice....I hate to bring up an older post, but has anyone had an issue of the Bluetooth being substantially quieter than the FM radio? I can listen to the FM on 6 while driving, and I need the Bluetooth to be on 25. Is there any solutions to this issue? I've searched the internet, but nothing seems to work. It works fine in my Hyundai that's 3 years older than this van, so it's not the phone.
