Thanks loaded the Updater for the SD card, it seemed to update as the screen showed....LOADER.....LOADING SOFTWARE. How do I check to see if updated?. Did I need to remove GUPDATE.GCD from system first because I did not. Not yet tried the JCV on simulation but have now noticed the map will not load from SD card GMAPSUPP.IMG . Internal map working OK... Have to go on motorway run later I will report what happens, thanks for your reply
