Garmin Power Tap Multisport Function

Have got myself a powertap and are using my Garmin as the output. It is working great however I would like to know if you have to have the garmin in the multisport mode or can just have it in the normal bike mode. My bikeshop set it up like that.

Thanks

You can just leave it in bike mode. The only times I have had issues with the Garmin is in multisport mode so I avoid it. You can set up the screens so that you can hit lap after the bike and then change screens to a run set up while still in 'bike' mode. Just select pace in the data fields for one of them. I use 4 screens, 1 has HR only, 1 power only, 1 HR and total time, 1 HR and pace. I rarely use the pace function anymore as I am far to unfit and it is far too hot to worry about it.
