Let me share my experience on installing Garmin.
First install Garmin.
Then I install MalSing Map June2007.
Then I update to latest version map of MalSing Map.
After update, it ask for lock code, and I m stuck.
So I check forum, and found MalFREE Map, I download MFMv141.exe (dated Feb2009)
It then produce .img file, and i copy to my Gamin folder.
Now every thing is perfect oledi for my N82 using Garmin with the lastest map.
Do checkout regulary here weekly or twice a week I'll update the maps here (MFM)...
