Edge 1040 Map unusable

My Edge 1040 is on V21.17

Built in Maps are virtually unusable because of thick black lines eiher side of roads/tracks

Garmin express recently gave me a map update and a FW update

I am going on a cycling holiday to Holland and uploaded openfietsmap BNL to my Edge 1040 and the mapping error is the same on that mapset

This points to the issue being FW related, as discussed in other Garmin forums

Do Garmin never read these forums! This issue will drastically affect my cycling holiday navigation
