How to add a garmin to a Boardman bike

It's a rather specific question, albeit with a confusing aspect that needs clarification.

Logging out of a web site when you've finished with it is just good practice. You can't possibly draw any conclusions from that. I've asked questions on forums and checked back for answers after a week or so. It's not a real time communication medium. Ideal for people who are busy.

I wonder whether @bernipete has lurked (they has not logged in since the OP) and got enough of an answer to their question?
