I recently went from a Starcom1 digital wired system to a Sena SMH10 bluetooth system for the wifey and have no regrets. I link my headset to her, the Zumo and to my iPhone. Music sound quality is way better than the Starcom1, and no wires. I really like the Sena because all functions can easily be accomplished with gloves on...no small buttons to push.
I still want to buy the Sena SR10 so I can use my GMRS radio to talk to my riding buddies.
I've tried what you're suggesting here and I would recommend you wait until the SM10 is available. If you're looking to connect the GMRS radio via the SR10, the only way to also get your iPhone functions to the SMH10 is to connect to the SR10 connected with a cable. The SR10 only trasmits in mono, and the sound quality is TERRIBLE to boot.
I've not even tried to have everything connected at once since in my normal commute the iPhone to SMH10 connection is all I need, but there's no way you would want to live with the lousy sound quality when your iPhone has to pass through the SR10. I'm going to try and get a refund on the SR10 or at least some kind of credit towards the SM10 once its available.....
just my $.02
Looks like the SM10 does not have the same radio connect feature that the SR10 has. Is that right?
Can't you connect to the iPhone from the SMH10 for the stereo sound and then connect to the SR10 for the other mono stuff?
I believe that the SM10 WILL have the radio connection of the SR10, but with stereo capability (which the SR10 lacks). I've tried various sequences of connecting the iPhone, SR10 and SMH10, but the best I can do via Bluetooth is one connection at a time. The official documentation on the Sena site and my confirmed experience, is connecting the iPhone via a hardwire to the SR10, then you're left with a horrible mono connection. Maybe OK for GMRS radio and mono commands from a GPS, or beeps from a radar detector, but no way tolerable for music IMO.
