Reading this Garmin forum thread it appears Garmin are close solving the problem.

Hello

Displayed on my Garmin devices with maps made with mkgmap is a North arrow that is beige in color. Not highly visible and I use the North arrow allot.

I want to change this to a red arrow so that it is more visible.
Is this possible via the .typ file or is this a firmware setting?

I have searched but it seems I am the only one interested in this change.

Thanks Pitney
