Greetings, Recently I stumbled upon a problem that left me scratching my head for a while. Search in Mapsource wasn't being enabled while it worked fine for the gmapsupp.img in GPS. The _mdr file was several MBs size, so indexing was obviously taking place. After tweaking the build/deploy script, I found that an extra dot in the overview file names was the cause. The extra dot is due to my particular naming convetion following this pattern: <family name><MM>.<DD>.img MM and DD are the month and day of build. Of course this was simple to fix. I just changed my build script. But I think an error or warning could be thrown by mkgmap or at least a notice in mkgmap options help page so others can avoid this pitfall. all the best and great work, Paulo Carvalho
