What you are referring to is applicable with Liftmaster/Chamberlain/Sears Craftsman openers made with the "Security +2.0" rolling code system. As far as I am aware, this is only an issue on openers made by Chamberlain in the last year or two, and does not apply to Genie openers. If you have one of the openers by Chamberlain, then there is a repeater module that plugs into an outlet in or near the opener that translates the older Homelink systems in our BMWs to the newer codes.
