I am quite surprised how little information is available to address a recent issue with the Maps application not reading offline map tiles on the iPhone/iPod touch despite creating system links. Turns out the existing MapTiles.sqlitedb is not compatible with the latest 2.2 firmware and the database needs to be converted. More information here:

Once converted, simply SSH over the converted file to the ~/Library/Caches/MapTiles folder. I have tested it and works perfectly now. You can use Touchcmd to quickly configure and rename files to swap map tiles if you intend to use multiple geographic locations. Otherwise, simply replace over the MapTiles.sqlitedb and you should be up and running again.
