wife wants to talk while riding, been looking at Sena but I don't know anyone to help install them . Is it simple to install or should I keep trying to find someone to do it. Get confused when they start talking about syncing, blue tooth, reaching up to talk, I'm confused just typing this out. also I see they have a controller for the handle bars for an extra $99.00 is it worth it? may need to be walked through this like a six year old.
