Garmin distributes new releases in stages over a period of a day or two.

The update will be available shortly either OTA or via Garmin Express.

The 128 GB microSD card with all my maps, POIs, BirdsEye imagery, tracks etc. which didn't work with firmware 4.70 is OK with this version.

Really?

What brand and type?

That is interesting.... And very good news for those using microSD cards over 32GB in size!

Was there any detail of anything from 4.20? That’s a lot of minor versions skipped?

Five posts down from this one, in the same forum, is the GPSMAP 66 Firmware 4.70 thread. You will find there were a lot of updates and improvements between 4.20 and 4.70, that is why so many 'minor versions' were skipped.

Art, have you visited GPSrChive? If not, please do!

Once you have GPSrChive loaded in your favorite browser, start by selecting the desired device (in this case, the GPSMAP 66), then select the 'Firmware' page to view a list of all the release notes for each and every firmware version for the selected device!

This section:
GPSrChive > GPSMAP > GPSMAP 66 >Firmware

GCD Updates

Current (non beta) firmware updates are available directly from Garmin using the URL https://download.garmin.com/software/GP ... r__xyz.gcd and substituting xyz with the desired three digit firmware version. For example, to download firmware version 2.80, replace xyz with 280.

Is no more valid :geek:
