For JCV take 'D3191170B.jcv - SplitScreen Full version Nuvi 24xx 25xx' from initial post, SID files from second post and SQLite from third post of [Only registered and activated users can see links. ]. I've explained previously about the ASR files, but they aren't posted in the 'revision' map thread so if you want Voice Command fully functional you'll need to try the ASR'2' files [for 3490] from P#52 the previous map thread: [Only registered and activated users can see links. ]. Ditto for D4919050A.img Foursquare map from the initial post there as they haven't been posted in the later revision thread either. Might work with the revision map.
