Is there a possibility to reinstall versions prior to V8.80?
And if so, how?

Yes, read the instructions for "GCD Updates" here: https://www.gpsrchive.com/GPSMAP/GPSMAP%2066i/index.htm
Many thanks @kiwiGPS. Great page!
As far as I can tell, only the most recent version is available for download direct from Garmin. At least, I was unable to get any version other than 8.80 when I tried it.
GPSrChive itself has older versions available for download as .zip files.
Quite easy to come back to previous version. From my view V8.80 is a step back, installing v8.50 some isuues disapear. Thank you very much fo the help.
