Hello everyone. This is my first time posting on this forum so bear with me please. I have three garmin GPS's. Two are of the newer generations and I have had no problems with either of them. The oldest is the 2757 that I have had for years but still works as good as the newest one which I got only a week ago. My issue is I no longer have the cable to update the maps and software. Don't have a clue where it is. The one for the two newest ones work for them but will not work for the 2757. The Garmin Express will not recognize the unit. I ordered a cable off ebay that said it would work on the 2757 but I got it today and it will not work. Does anyone know where I can get a cable that will update the maps and software for the 2757? Thanks in advance, Lost in space.
