I recently bought the cardo units SHO1 set designed specifically for the shoei neotec hats, I think the units are pretty much identical.
They are good, all I wanted was to be able to talk to the wife when she is riding her own bike and to listen to the Garmin. It does this very well.
It will also play radio and link into other units via Bluetooth but I'm not remotely interested in that of the phone.
The range is given as being circa 1 mile in intercom mode and it is. It's very clear just on Bluetooth.
The Garmin links in easily with it. The only problem for me is that when the Garmin is speaking, giving directions I am unable to speak with my wife and give directions immediately resulting in occasional wrong turns but we can live with that.
Great kit!
