Hi, I have the SMH10, I connect by bluetooth to my phone and Garmin Zumo 660 GPS. I have music on the GPS but quality and volume are poor at best. What I want to do is connect an ipod with a cable into the MP3 port of the Sena. I know this will work but the question is will the MP3 pause when the GPS is giving directions?

Not in a position to test this right now, hoping someone knows off the top of their head before I go buying an audio cable. Thanks!
