Fly Garmin Nav update question GTN650

I'm going to update to the latest 6.41 main SW. I never updated to ver 6.21 so my question is on the newer style NAV data. When using the fly.garmin.com downloader how do I check to be sure I'm downloading the new format. Don't see any button or area to pick the newer style NAV data.

Appreciate the help

Gary

Gary, the current nav data is the new format.

Thanks Pat.
I was kind of thinking that but the installation instructions (service bulletin 1723) says......

Make sure to select the Navigation databases for GTN Main Software Version 6.21 or later when downloading databases from fly.garmin.com.
