Thread: Garmin Maps expiration Date

I've tried with 2 different cards (32GB) that work fine for the regular updates. Tried today with disconnected from the NMEA network with no change in the outcome. I wanted to try with a 2 GB card, but it won't quite fit. I'll look for a new card tomorrow and give it a try. I did discover on another thread ([Only registered and activated users can see links. ]) a successful roll back on a 7400 series. Not sure if it's a straight chartplotter or a combo like mine. Fingers crossed.

I've been using 16 GB card that have worked well in the past. Tried an new 8 GB card today with networking disabled - no change ( see [Only registered and activated users can see links. ] #5). Then tried with everything but the power cord disconnected, and again no change. It's looking like I'll be using my laptop for my custom charts. Thanks to all for the suggestions.
