I can adjust the volume on the radio unit after fiddling through 3-4 screens. It is by no means simple or safe to do while driving. I have a Pioneer AVIC Z3.
When the BB is connected to the BT the volume controls on the side are not functioning at all. The volume level shows to be in the middle by default. If I disconnect from the BT the volume controls are functioning again.
This was the case with the 4.3 OS and also with the 4.5 OS.
Any ideas?
