Can't legally use a CB in the UK. Their emergency services use those frequencies. UK bikes have different system.
If you have a UK bike you want to setup for use in USA / Canada areas you may have to go with a J&M system which is a complete system that would not patch into the wing's wiring. (You *COULD* patch in the audio, but it's not very easy from what I understand.)
I know about the UK stuff cause our drill team couldn't use the cb's at the Blackpool Gathering.
