Stripes on GTN750xi Map page

I’ve seen this a couple times recently. After a couple minutes, display is normal.

It's the ADS-B FIS-B weather overlay. There can be incomplete data that then gets filled in when you are in better reception. If you were to toggle that off momentarily, you should see it disappear.

Yeah the FIS-B weather is probably set to U.S. rather than regional

[TangoTango]

I don't think it matters whether it is set to continental or regional radar (other than speculation that the lower resolution continental radar may load quicker since it presumably requires less bandwidth). I've seen the same artifact many times on my 650xi at low altitude despite normally keeping mine set to regional, and once I climb out and get ADS-B reception the data always fills in.

Interestingly, I noticed on a recent trip across Wyoming on V6 at the MEA (10k MSL, but only 2-3k AGL) when I had poor reception the FIS-B seemed to be smart enough to load a smaller than normal ring of radar data around my location first, then expand as I continued down the airway toward an area of better reception. I thought that was neat, as it's the first time I'd spent a significant period of time with marginal FIS-B reception at altitude.
