Hi Karl, I've seen this problem on my Oregon when another map was installed (but not activated). The map was the Bicycling-Layer for Europe from http://osm.thkukuk.de/ I did not find out why it caused problems, but after renaming the corresponding *.img file the search was fast again.

I generate maps using the following options (among others) --net --route --index --split-name-index When loading the ready img file to a GPSMAP 66st it is very slow in searching for cities (FIND -> Cities). Searching for some location can take many minutes or even lock the unit in rare cases. The problem is present even if a specific map is selected and search is only conducted within that map. Loading the same img file on an old etrex vista hcx did show very fast city search. Does anyone know if the options given to mkgmap can impact negatively in this particular scenaio or if there can be some other option added to make city search faster? Side note: street name search is fast, but searching among All POIs is also slow.
