Something indeed has changed! You apparently didn't read my post earlier. See video. Also, although comms are not needed, they do change the way group rides go. I know at least 4 riders who have just discovered riding with comms and they love it. All of them said the same thing, it changed the ride for them.

The one problem with a lot of these comm systems is that they can change so quickly due to firmware update releases that sometimes their website info and online manuals are not up to date. Ironically, a VFR member (Rambler) had pointed out to me about the Cardo Gateway feature. I hadn't really taken a good look at what the latest firmware added/fixed.
