Well…. Since you asked. While I had the NAV/VOICE button pushed in and then turned the volume to increase the NAV voice the RADIO volume also increased. However, going back to the RADIO and lowering the volume did NOT effect the NAV volume. As I noted in my first message, I had selected the MAX in the NAV options. If I remember you have three choices, a MIN and MAX and one in between, do not recall what it is called. Since I could barely hear the NAV voice, I figured setting this option to MAX would fix my problem.. Wrong!!! So this option has another function….
