Good for music, but calls maybe just OK.

Received it yesterday and installed in my son's car just fine. Sound quality for music was great with no buzzing or background noise. However, conducted several test calls with car parked and running with mix results. When car was parked, calls came in clear but the person on the other end said they heard echoes. When car is moving, they said they could barely hear me. Other than that, it's quite good. The cord for this application was perfect as the aux input in his MDX was in the center console.
