It has be reported several times in the list that address search doesn't work on nuvi 300 (spell country problem). I have recently built a map that includes Portugal, Spain, Switzerland and part of France, Italy and Germany. For my surprise, some countries are found by nuvi and I can go ahead with the address search. This is the list of countries that can be searched: Type S, finds Schweiz, Suisse, Suiza, Svizzera Type F finds France, Francia Type I finds Italia Type D finds Deutschland Type A finds Alemania Type L finds Liechtenstein O: Österreich Some other countries that are in the map can't be found as Portugal, Spain-España. I'm now out of home for some holidays and can't put the map available to download till next week, in case some of mkgmap gurus want to dig into it to look for what does this map work.
