European Maps

Either give Garmin more $ for the maps (but they might not fit?) or look at OSM map sites like https://extract.bbbike.org/ what will allow you to tailor a specific area for the map extract, make sure you use the Garmin (Latin1) formats and remember that these sites exist due to the work of non-commercial individuals and a small donation helps to cover costs and keeps the servers serving. The process is very easy and DC Rainmaker did an overview a few years back (some of the sites he mentions no longer exist for the reason above)

I have used BBBike in the past for use on our older Garmin 800. Have not tried it on the Explore 2.Do you know if it works on a Garmin Explore2?

I do it all the time on a 530 and a 1040 so no reason to think explore is any different, plug it in to a PC or Mac and see if you can view the Garmin as a file system, that’s all you need (recent Garmin software version have changed things in this area and made life more difficult for Mac users)

Thanks  for your  response!  I will play around with it this weekend. 

In the past BBBike maps ha e been great and worked well for us.
