I used to configure the Garmin 430 with a timer set for 30 minutes that would remind me to switch fuel tanks. I usually remembered on my own, but it was a nice warning. The Garmin automatically did this when it was turned on. However, on my GTN unit I can't find an equivalent. I see there is a generic time that can be preset, but its up to you to start it which could lead to it being skipped.

Is there someway to do this with the GTN series?

I have a 650 and as far as I know it doesn't have a fuel timer/alarm. My EFIS (G3X) does though.
