I have a couple of Shoei Neotec I, that I have the Sena 30Ks mounted to. And connected to my Garmin Zumo 660.
I then bought a Neotec II, and I didn't like mounting the 30K back so far, so I bought the Sena SRL 1. The first time out, I hated it due to the volume control buttons. I then connected my "wrist" remote to it, and I can control the volume through that. Then on my trip out to Kaliforniastan, back in January, I forgot to charge it overnight. 30 miles into my trip, the message was coming up saying low battery. That continued for the rest of the trip to Elk Grove, which was about 2 hours. I was surprised it lasted that long...
And nothing like throwing a wrench into it, I up graded my Garmin Zumo 660, to a Zumo XT. I have managed to get one of my 30Ks to communicate with the XT, but I still need to add the SRL 1 and the other 30K, and my phone, as I had it connected with my 660.
It seems, everytime I "Upgrade" I seem to loose functionality that I had with the previous unit!
I just love advanced technology...NOT!
