Hi Butters

Thanks very much for the advice and your patience. I eventually found the G spot just above the G and got it to boot. I found two files for the 3597 and ran them through the Garmin Cure 3. A 540 and a 550 file. I ran them through the Garmin Cure 3 and then the updater once I got it to boot the GPS. Now only the logo appears on the GPS and then it switches off. I tried both files with no luck. Any suggestions please?
