i was looking at that one but it doesnt seem to use the same communication protocol the X1 does. meaning, it uses some other way to communicate with other riders instead of the channel setup the X1 has.
XBi communicates on a single proprietary channel which only communicates other XBi's onless you got a motorola and get on its same freq range, u wont talk to it...its a bike to bike...as long as its 2 same modules....so really a bike to passenger module..
