Is there any way to set the audio/video volume to decrease when the GPS is giving commands ? I know there is a volume setting but I cant find a way to make it "auto dim" audio.

I had an Alpine INA-W910 in my truck last week (swapped it for the AVIC-Z140BH) and it did auto decrease the music volume.

Yes. In the LANGUAGE or TTS voices settings. Details are in the manual.

I havent had time to even get the Manual DVD near my computer.
