How have you tried that? My proximity circles have always been yellow and I've never found a way to manually change that?
Perhaps they vary depending on what you've selected in Setup, Display?
I was referring to setting proximity alarms manually on the unit, vs setting them in basecamp and then downloading them to the unit.
I hope we can figure this out. Forkeye's unit displays in red, sussamb's unit has always displayed them as yellow, and my unit has displayed them in both red and yellow. So, we know that it is possible to change, that's a start!
Thanks for the input so far!
