Long delay in receiving map

I’m trying to get the OSM for a garmin Edge 830 (bike computer) for the UK.

Is it correct that there is a 32 day wait? This is the message I’m getting - I’m doing Lands End to John O’Groats at the end of next week!

You probably refer to http://garmin.openstreetmap.nl ? This service is not reliable since many month.
Try other sources, e.g. https://extract.bbbike.org/

That website is not maintained for over a year. Try
http://www.openfietsmap.nl/downloads/europe for a UK map.
