I had an issue with one of my systems, logged it with Garmin, first steps Garmin help desk advised me to update my firmware to rule out software as the problem - this didn't fix my issue and I now have the until March to sort out my maps. I solved my initial reported problem by buying a new Garmin Reactor CCU - the faulty one is being returned to Garmin.

My GPSMAP unit is:

<PartNumber>006-B1878-00</PartNumber>
<SoftwareVersion>1100</SoftwareVersion>
<Description>GPSMAP 7408</Description>

I would like to revert to the earlier firmware, however the only mechanism to do this is via the SD card slot, and I cannot find the earlier firmware. I think the file is GPSMAPSerieswithSDCard_20170825.exe. I suspect Garmin have removed it from their site. But I can find a trace reference of this file in Google.

Can anyone help?
