On my Garmin Edge 520, it seems I can only run a max of *4* custom data fields. Even if say 2 are on one screen and 2 are on another screen. They do allow all 4 (max number) on a single screen.The data fields are only executing when the screen is active. So I would think Garmin should allow the limit (4) on a per screen basis.
My question is... does the Garmin 820 allow for more than 4?
Thanks!
