Hi, are these maps works on Montana 7xx series? I get “Can't authenticate maps. Contact your content seller for help.” on the screen. Any solution for this for Montaya 7xx devices?

Thanks in advance

Hello. I would like to ask for help. I did a software installation from Garmin Drive 50 LMT to Garmin Dezl 580. I got a Garmin Dezl 580, I got the parameters for the truck mode, but the problem is that I can't download maps through Garmin express, and the name of the device Drive 50 is written in the XML folder, and that's how Garmin express recognizes it. I inserted a 32Gb external memory card with a universal firmware for Dezl 580, however, it does not "see" the memory card, but reads all the routing paths from the device. I loaded the device with the latest maps via BaseCamp. I hope I managed to explain the problem, if there is any explanation for this problem I would be very grateful for any kind of help.

Are you talking about the Firmware Patch kit for HWID 2826 ?

If you want, make a copy of the original garmindevice.xml from your back up of your Drive 50 and put it into my [Please Register or Login to download file]

Yes, I’m talking about that.

" If you want, make a copy of the original garmindevice.xml from your back up of your Drive 50 and put it into my Drop Folder. "

I sent from the device and from the SD card.


Sorry, I made a mistake and renamed it to sys instead of xml, do I need to send it again?

I replaced it with ID, but when I restarted the device, it returned to the previous ID.

@trifke
The device id is hard coded into the device it cannot be changed, when a re boot is done the garmindevice.xml is overwritten with hard coded details.
As I wrote above substitute the original ID number from the Drive 50 in the garmindevice.xml I shared with the fake <Id>3987654321</Id>
Create a folder called Garmin on a clean SD card 32gb or less and copy the garmindevice.xml to it. Use Garmin Express to download all the file including the unlock files .unl .gma for your specific device then copy them over manually. This is the list of files and location.
