are you sure you're not sending maps with MapInstall 4.2.0?

Meaning are you sure you did not destroy the .img files using Mapinstall 4.2.0? Use mkgmap itself to generate a gmapsupp.img (of a non unicode map just to be sure - maybe the firmware update crashes unicode maps but I've not heard of that for etrex 20/30) and check if that works.

Can you not downgrade the firmware?

OK, that is probably nothing that we can fix in mkgmap :-(

Well, as there was no map displayed, I couldn't select a point and try
to get a route to it. What I did do was go to a Waypoint and try to
route to that. It failed as I said complaining of no routable map.

Again, as I said earlier, what did seem to work is to select a recent
find, and route to that. It showed a route which was following an OSM
map complete with street names. Of course, the map that it was following
was not shown. But, again, as I said, maybe that was out of some cache
rather than using the current map. I had no way of knowing. Perhaps the
cache held the "track" and the list of names; as in the route display,
or whatever that menu option is.
