This is the cable I've been waiting for. It's kept my SR10 up and running for hours & hours, streaming everything I throw at it. As long as the bike is running the SR10 is powered through a switched cigarette lighter adapter I installed in one of the fairing boxes. It's more than met my expectations, auto-power on enables auto-sync so the only thing I have to do is turn on my SMH10's. This is a much better alternative to charging, or trying to remember to charge, especially after a long day in the saddle. I highly recommend anyone with an SR10 avail themselves of this option. You won't regret it!
