Found a really interesting feature in my friends BMW 3 Series (2012 Model) today.
When connected to his phone (iPhone via bluetooth) and he is using navigation apps like Apple Maps the voice is played through his car sound system even if music is playing through the system (via local media or the phone). When a direction is said aloud the music volume drops and the direction is given and then simply reverts back to the previous media. On his system it appears as if someone has called him when the directions are spoken.
I wanted to know if something like this is possible using the AMI system? I know if your playing music via bluetooth (on iPhone) and then have sat-nav running it will speak through the sound system but is this possible when your playing local media? i.e. iPod or SD card?
