Good link regarding the differences. One thing that they barely mention is that you can use earbuds with the 10-11 and not the 10-10. I found them for about the same price on fleabay, so no reason not to go with the 10-11. i use a modular though, so YMMV.
Thanks for the replys and sites, they answered my questions on the SENA units and even showed I was looking at the wrong SMH10 unit for the helmet I have.
I also found out what was cousing the trouble I was haveing with cranking the bike, in past posts.Seems that some after market batterys just don't have the amps to turn the FJR motor. Thanks again.
