Garmin GTN650 Terrain Data

[wilkersk]

Anyone ever seen this?

Gear: Garmin G500 package; GDU620/GTN750/GTX330

All databases are current except for the Terrain database on the GTN 650.

On the GDU620 splash screen it show terrain as current.

On the GTN750 splash screen it shows terrain unavailable.

On the GTN750 System Status screen it shows the terrain available on data card.

I suspect I know the answer. But, I've been unable to find it in the documentation.

Here's pictures:

The Terrain data "available on card" is still the 20T1, same as shown on the splash screen of the GDU.

Would not be surprised if that is it though. I won't get to see that airplane again till Saturday. I'll check it out.

Kinda reminds me of the GNS430 where it says NavData "Expired" (past tense) 28 days from now.

It's in the standby, not in current. I'm assuming it's not present in Current which is why it says "not available". FWIW, 20T1 is current.

I don't remember the exact sequence of buttons to push on the GTN to copy it over from Standby, but I'd start with Menu on the pictured screen, or maybe tapping that database directly.
