Was doing a Garmin 2597 update. Software updated to 8.80. Map showed 7GB download. Started saving to "device + computer" eventually failed. Now Garmin Express reads "You're up to date!"
Checking map version and it is still CN North America 2019.30 when new is 2023.20.
.system/ folder shows gmapprom.img of 2.8GB with a date stamp of 2018-11-10 corresponding to the old map version
Garmin/ GarminDevice.xml can be edited to re-install all the software/firmware but not the map.
If the .img file (and associated files .gma/.unl) were made available I could just drop them into the .system/ folder and be done. But... this has taken way too much time.
I'd be grateful for suggestions.
