Zumo User Forums

Hi Folks,

I wanted to reinstall my System on my Garmin Zumo 390LM. Fot that I downloaded the gcd-File from http://www.gawisp.com/perry/. I exactly downloaded the zumo3x0_GCDFile_420.gcd. It should be the actual firmware-version 4.20 of the Garmin Zumo 3x0. I placed it in the Garmin-Folder on the Zumo 390LM and renamed the file gupdate.gcd. Now you should just reboot it and it should start flashing. My zumo starts normal and not in flashing-mode.

Does anybody has experience with this? I think I have to enable anywhere the flashing-mode, but I do not know where.

Since two month the system of the Zumo is instable. I already made a factory reset. But it did not help. Now I wanted to give it a try to reinstall the system.

Cheers.

It needs to be placed in the .system folder, not the Garmin one

If I put the gcd file from my Zumo 390 in the .system file of my 395 will the 395 function like the 390?
Thanks

No idea, sorry

Thanks for the reply.

Probably not no as I believe that they are totally different units

Thanks for the reply. Physically they seem to be identical on the outside but they could be internally different.
