Hmmmm, that date is a full week BEFORE the previous version, 5.80, was published.

Something is not right here....

Sorry for the dig, I am investigating on the 276cx and found this, url doesn't work anymore, did garmin take it out also from express?

[GPSrChive]

As best we can determine, there was no 5.90 update, and this was a glitch.

The 5.80 update is still available on the Garmin server, indicating it is the most recent.

Interesting, I wondered about that.
I have all the others backed up but was unable to get 5.90 to save, I guess that's why.

Interesting that your device reports Audio Package 2.20, while some earlier firmware reported 2.30.

Version 5.90 is not a glitch. It's still offered for 276CX via Express. The old links are just all dead. I am not aware of a replacement, only download via Express. I do also have the GCD, if anyone want's it.

Btw, the 276CX is EOL.

Garmin Express tells me that there is a 5.90 update for the GPSMAP 276Cx...

It's just that you can't download newer update files from the Garmin webserver anymore.
