    Question: is there a way to delete old maps? I have 2016.2, 2017.2 and .3, and 2018.1. If there is a way to remove them, is it a good idea? I think routes "know" what map was used when they were created and re-using old routes will require them to be recalculated.
    I updated my zumo 590 and laptop yesterday. I searched little and found that the old map on my computer (2018.10) could be deleted by using the same method as uninstalling a program. On my Win 7 machine that is via the Control Panel -> Programs and Features.

    My understanding is that if you use Basecamp to convert your routes to tracks, and then, using the new map, re-convert those tracks to routes, you will more likely end up with the original route. Being a list of coordinates, a track will not change, while a calculated route can vary with the map and routing preferences..

    Beware! I'm new at the Garmin way of doing things, and could easily be wrong.

    Old maps can be deleted by using the control panel just like deleting a program. The maps will be listed in the programs list.

    You can delete your old maps (and lots of other stuff you don't need) from your Garmin with File Manager. It's as simple as finding the file (Maps are in the Garmin\GPX folder), highlighting them, and hitting the delete key. If you're concerned that you might accidentally delete a file that you really do need, first copy it to a thumbdrive, then delete it from your Garmin. That way you can replace it if you need to.

    BTW, GarminExpress should delete the old maps during the update process, only leaving the latest map(s) on the device. Not so on BaseCamp, as BaseCamp keeps all the old maps. I assume that's so you can match BaseCamp to whatever version of the map you have installed on your various GPS systems.

    Other files that can be safely deleted are voices you're not using, pictures, tracks from old trips, icons for vehicles, index files (which may not be deleted by GarminExpress, but old files are not needed). FWIW, I've had the Garmin Support desk help me identify some files that can be deleted from my unit(s). (I own four different Garmins)

    The Garmin Express update is independent of the map updates. You can update using the web updater or from inside base camp.

    My Nav VI is stil on 2018.10
    My Nuvi 66 now has an 2018.20 update ready to install

    It might be due to the fact my Nuvi is NA maps and the VI is Euro....

    That would be it, the map update is for NA. Not sure what version they're on currently for Europe, I have my maps for Europe on an SD card so I can switch it between units, but I'm still on 2014.40 ($100 for new one).

    Garmin Update to 2018.20

    Just updated all 4 of my GPS units yesterday (NAV V, Nuvi 550, Nuvi 2539, & Montana 650). With Cable Internet, it only took about 30 minutes per unit, including updating GarminExpress. (I have 3 computers, so 3 copies of GarminExpress & BaseCamp). All units have been upgraded to at least 16gb storage on an SD card, so plenty of room so far. This 2018.20 update was a different size mapfile for each unit (as expected), and GarminExpress deleted the 2018.10 file after installing the 2018.20 file (on the unit, not on BaseCamp). This was the first system/map update since I bought my first Garmin (Nuvi 550, probably about 10 yrs ago) that went smoothly on all units, with absolutely no glitches in the process! Thanks, Garmin, for finally getting it right!

    This was my first update, so I had to download and install Garmin Express first. Then I used a random cable to try to connect the Nav V to the computer. Express didn't see the device but pointed out that some cables are only for charging and do not carry data. So I dug out the cable from the Nav V box. Express then saw the Nav V. From that point on it was just a few clicks and a wait of about an hour or less and both the software and the maps on the Nav V were updated.
