When I was setting up to do my Coast to Coast last january, I bought a Chatterbox system. My thinking was that I could hook up my iPod and also have the ability to talk with other riders on future rides. I didn't end up using it.
I found the speaker placement in the helmet a bit difficult to get comfortable. The unit itself seems to work just fine, and the device can me mounted to the helmet or on the tank bag with an extension cord.
So its sitting in a box. If anyone wants to buy a slightly used Chatterbox system, PM me. I'm returning to the classic way of communicating with passengers -- nods, yells, hand signals.......and if they're really cute women, the odd grope and squeeze ! Woo Hoo !!
