I tried I don't know how many of those bluetooth transmitter things. Either the battery didn't last but 5-6 hours or they would auto shut off after 10 minutes of no signal, then 15 miles down the road you get hit with a radar and then a ticket. None of them worked, so I got the SR10, I already had the SMH10 and haven't looked back. I run my radar and gps through the SR10 and I can hear them both if the gps is talking and I get a radar hit. I also can hear the radar or gps if having a conversation with another sena headset.
I know it is a lot of money, but if I had just gone with the sr10 to begin with, I would have saved a ton of money.
