I have been tearing out my hair after 2 days of hell with a Garmin NÜVI 2597 Sat Nav. I tried an update & to cut a long story short if formated the Garmin & not the Micro SD card. So far as an Apple user I have had to build a windows machine on an old lappy. Follow all your kind help by reading every post & installing software. I managed to get into the Garmin & retreve the following:
ID2077 NÜVI 25x9 Version 8.80. Grok tells me I need NUVI 2xx7and 2xx8c4_800.gcd. I cannot for the life of me get that firmware anywhere with out it going corrupt. Can anyone please email me that file please? [Only registered and activated users can see links. ]
I believe these are the next steps:
Open the .gcd in GarminCure3.
Create the Cure version and flash it with Updater.exe in preboot (same timing technique you’ve been practising).
Once the unit stays connected and appears as a drive, check/delete any obvious bad files (especially anything in the root or .System folder that looks recent or corrupted).
Then create and flash the original (non-Cure) version of the same firmware.
I am hopeless at text forums so apologise in adavnce

Any help appreciated,

regards
