Thanks again Butters. I know Im getting closer. The fact that I can get to the ' initialising ' part means its nearly there and details have been read from the unit, so Im getting into pre boot ok to get this far ? So the download is just about to start on the progress bar, again shows a positive ... then error .... 'Garmin application failed' pops up with no progress on the bar. Ill keep on trying as you suggest. Thank you for your patience. Ill read again all your info too.
