New Radio Feature?

[Video Chef]

I just hadthe Radio Module replaced in my '02 X5 with Mk III Nav and no DSP and now when I am listening to a CD or the Radio, when I hit Info it displays a new option with RDS and PTY called Nav-Min or or something like that. When I hit the select button it goes to an adjustment option for + and -. Is this a way to adjust the Nav voice prompt volume or relative volume without going through the service/hidden menu?

I'll bet it's the same as the TP volume setting - which I believe is traffic warning volume.

Your old radio probably fully muted when nav instructions came over. The Nav-Min function on the new radio adjusts how much the radio mutes with nav instructions. It is kind of nice, because you can set it so that it does not fully interrupt the music.
