I've sometimes referred to having my own mapping software running on my car PC but not been in a position to share it, or at least there's been no point sharing it because the only maps it worked with couldn't be shared due to copyright reasons. I've been fiddling with this software on and off for a long time now and more recently I've made it work with other map formats like tiff/jpg with world files and the older none encrypted MemoryMap QCT files and plan to add others when I get hold of them. I've also converted some of the Ordnance Survey Open Data maps into a format TE can use so it might be of some use to others now. 16MB TE installer for pretty much any version of Windows that has DirectX9. Track Explorer v2.26 An index of the free OS OpenData maps that I've converted so far. If you have a Wayfinder account you can download information directly into Track Explorer. Have a play, or not, it's free.
