I also have smh10. This is great company to deal with. I updated my firmware to 5.1, it made even clearer, like she was siting next to me. They also made it easier to update the firmware.

I bought the smh10 at Spyderfest last week and can't get any sound from telephone calls or satellite radio. I updated the firmware to 5.0.1. and the lights on the headset appear to show it's paired with the dongle. Any advice would be appreciated.
