I think there was a setting on my 3RX to reduce volume or completely mute the current audio source when the navigation lady wanted to talk to me. I haven't found it on the 4RX menus, nor in the manual. It's not working that way be default in my car. I can adjust the navi instruction volume, but I can't find a place to lower the audio source volume when she's speaking.

Anybody know if this is possible in 4RX, and if so how to do it?

Thanks!

 

I'm also interested in knowing if this is possible. The best I can do is turn down the volume, then press the Map button on the Remote Touch pad to have the instructions repeated.
