This 2012 is equipped with just about all options. Audio components are labeled Bose...
When NAV is providing audio guidance to a destination, the RADIO cannot be separately controlled. If I change the volume control, both NAV and RADIO are effected equally. Obviously, I cannot hear the instructions.
When the RADIO and NAV are both turned off and I press the NAV button on the dash, both NAV and RADIO turn on.
I don't think that's what was intended. Did I miss a configuration or control option, or is there a malfunction?
