These are expensive, but super nice!
They come with a Cardo Systems Scala headset and a mounting system for the GPS
(pretty much everything you would need to get it up and running)

Putting it on:* TurtleDevo did this
* He had no trouble with the software (on his Mac), but others have reported challenges
* The kit does seem to be very complete and easy to use (but probably not as easy as they claim)
Using it:* I've been using it down in Columbia SC, where I get lost instantly
* This GPS unit combo is great!
* The headset speaks directions into your ear, so you don't need to look at the display
while keeping track of those pesky motorists
* It's easy to:
...* Enter new places
...* Get home from wherever you end up
...* Set it to avoid highways
...* Go whichever way you want and have the GPS automatically adjust your route
...* Reset it for night colors
...* Remove it & stash it under the seat when parked
* It's a little more challenging to:
...* Link it up with the headset
...* Use the map feature to figure out where you are
* And it's not a good idea to:
...* Try to change the settings while moving
...* Leave the GPS unit or headset exposed while parking, since it's easy to swap them between bikes or helmets
Summary of what I think of it:* It's really, really nice!!
* It's pretty much idiot-proof to use
* It's expensive and would have a high vapor pressure if left unguarded
