Good Day

I have a Garmin Drive 50 USA LMT. It originally had SW ver 5.40, overtime it updated to ver 5.60 and now currently 5.90. I unlocked it when at ver 5.40 and updated the GCD file as suggested. Since with ver 5.90 through Garmin Express it suggested to update the USA map to which I had full 49 states. Due to the device limit size of 4 gig I had to updated to the NE States only and all the other required updates. Upon doing so the gupdate.gcd file has disappeared and when I replace the gupdate.gcd file upon bootup it either says I have newer software to either boot to update or no update. Either way, it boots up fine but advises I have either locked maps or corrupt maps now. I have reformatted the SD card and replaced the unlocked maps in the Garmin folder of the SD card (which worked fine previously).
Each time I get the map error message and the gupdate.gcd file is gone from the device .System folder each time.

I am not sure whether with ver 5.90 my device has again been locked and why the gupdate file continues to disappear on boot up. I still have the original GCD file when at ver 5.40 so not sure what I can do to avoid the map errors.

Any suggestions would be appreciated. Thanks

I was able to get things working again by doing the following -

I was unsure about my gupdate.gcd file being missing so I got off the web a gupdate.gcd file for ver. 5.90. I ran it through the patcher, rgntool and then used the updater to install onto the device. When doing the update the device indicated it already had that version 5.90 and if I wanted to use my new version and I indicated yes. All loaded well.

I started the device without any SD Card in it and my current installed version map NE States (2020.10) loaded and no errors. I connected to computer and found again there was NO gupdate.gcd file to be found.

I loaded my SD Card with the previous maps I had on it before the update recently (which had worked fine). Using a newly formatted SD Card and creating the Garmin folder I put the same files in there North America (2018.30). I installed the SD Card into device and maps worked fine no errors.

I then removed SD Card and installed the North America (2020.10) maps and ran the maps through the unlocker to ensure maps were unlocked. I then installed those files on the SD Card after having reformatted the SD Card again and then with only the 2020.10 maps files on the SD Card.

I then installed the SD Card into the device and started it up. Device loaded fine indicating updated maps. No errors and checked installed maps and the new maps were seen as installed.

So all has been corrected/working and I am a satisfied user again. My question is the fact that there is still NO gupdate.gcd file to be found in the ,System folder. Not sure if anything has changed with the recent software version or not or for whatever reason my device just does not want to retain it like before with previous software versions.

Thats it and perhaps someone can comment on the missing gupdate.gcd file.

Thank you for your reply and suggestion.

If it is still present then why is it no longer visible as in previous firmware updates. Is the file changed to no longer be visible in new firmware. It was visible to me up to 5.60 but no longer with 5.90. I have again attached device to computer and file is currently still not present or visible.

I found my softwareversion en FWID, but can't find it in the 20-09-18_fw_list

Hi I am trying to update my nuvi 2599

H/w id is 1947
s/w is 880

I am on the verge of just getting a new map; I do have the latest for australia it just keeps saying they are corrupt cannot unlock; and downloads the partial version in basecamp

I have unlocked the maps using the gimunlock
I have deleted gupdate, patched it and changed to rgn ( I loaded it over using webupdater); it created a new gupdate file.
I have performed a master reset
I still cannot unlock the maps....

I have even converted the .img to basecamp extract and loaded to the garmin via that way, it still cannot open the map....

thanks

Firmware version as specified in GCD file: 6.40 for Unknown device (HWID 3061).
File format not recognized.
any help pls

The Garmin Drive 52, as all new Drive models (55, 65, etc) has Linux based Firmware.
Nothing to do until now.

The Drive 52 is running the Garmin OS (not Linux), but the internal contents of its firmware are encrypted.

Can I kindly ask you to edit my Etrex touch 25?
Many thanks, R.
