I presumed it to be more that 4 GB with all the information it gives. What puzzles me is the disk shows as a data DVD Rom and the content size is only 325 megabytes and this does not seem right. I am trying to backup a 2008 IS250 Lexus navigation DVD 2007-2008 ver1 and have not been successful. I also have a heat problem living in South Africa and many of my CD’s in my car have turned into warped coasters. I can not backup my Lexus 2007-2008 Navigation DVD and have tries all the recommendations on CD Freaks and now have about 45 coasters, this will eventually end up costing me a new car just to get a backup Disk. I am new to CD Freaks and don’t know how to post a question, so just replying to someone with the same problems. My DVD ROM drive reads the ORIGINAL 2005/2006 no problem after cleaning it! I recently bought the West Europe 2010 MAP DVD copy and the UPDATE DVD v4.40 to allow me to run the new MAP DVD. of 3 - FORD DENSO DVD MAP AND UPDATE - posted in In-Car Entertainment (Mk3 Mondeo): Hello everyone,i have a Mondeo 2006 plate and i have the FORD DENSO 7' TOUCHSCREEN Navigation built in. Tom Tom supply the mapping for the DVD based systems. It's the touch-screen Denso unit that Ford/Jaguar/Landrover all use.
