Mounting, earbud..bluetooth. Yea it takes some experimenting to figure out what is best for you. Took me awhile. I ended up on my handlebars with a Ram Mount but I have a big fairing so it has to rain really hard before I have to do something. So power from the fairing was easy, then I ran a aux cable under the tank that comes up right under my seat. Run the earbuds under my jacket and plug in. Also ran a second cable so I can just aux it into the bike's stereo. Can't really hear what she is saying that way but I can hear her...know that something is coming up and glance at the phone.
I got really tired of bluetoothing it, seemed like I was always dicking around paring up or charging. But that was awhile ago, the newer sena's seem to work much better than what I had.
