I installed this in a Nissan Titan. Each of the 3 people I tested it with complained about the sound quality - even though it was mounted on the visor only a foot from my head. So, the outgoing sound was poor at best. They each said it sounded as if it were over modulated. The incoming sound was barely acceptable. I had to return this and continue using a headset. It seems to work in other applications, but not mine.
