that there is a navigation system that clips on to your handlebars. Does anyone have this or have any idea who makes such a thing? I've searched but I've been pretty unsuccessful so far.

 

Harley sells it;

You can get one of these ---> http://www.webbikeworld.com/garmin-g...-gps-mount.htmthat work with several Garmin models.

 

You can buy whatever GPS you like (Tom Tom Rider, Garmin, Lowrance) and Ram Mount to attach it to your handle bars.
