I'm guessing I may not be the only one but here goes. I recently uploaded new maps on my Garmin Nuvi58. All seemed to go well. Garmin Express says the maps are there. However, when I turn on my Nuvi58 I'm greeted by "Detailed maps are required for routing. No detailed maps found on this device", Screen then changes to "Cannot unlock maps". If I look in the Garmin folder on the Nuvi it just has a link to the folllowing: C:/Users/wingreen/AppData/Local/Microsoft/Windows/INetCache/IE/8RY1KWP9/GarminDevice[1].xml.
I tried Garmin support but they were hopeless and just suggested I try re-loading the maps via Garmin Express. Same problem. So Garmin said they could sell me a new one! Now, its POSSIBLE, I disconnected the Nuvi too early (not sure). I've had the Nuvi for years and never had a problem with uploading and using new maps before. Any ideas? Is it a corrupt code or something? If so, is there a fix? Any ideas to resolve would be much appreciated.

So your nuvi 58LM only has a link and no garmindevice.xml in the Garmin folder on your device
Does the GarminDevice[1].xml on your PC look like this.

Sorry - I'm hopeless with IT. I tried those links but got completely stuck. This what is in my Garmin folder on my Nuvi58 (its just Nuvi58): GarminDevice.xml. It looks like a Bing link. It takes me to
file:///C:/Users/wingreen/AppData/Local/Microsoft/Windows/INetCache/IE/7MTAO6M1/GarminDevice[1].xml - but that folder doesnt exist on my PC. I tried Garmin support but they were hopeless - just offered me a discount on a replacement - which was still more expensive than a Garmin I could buy from Currys. Sorry - I'm not much help.

Rebuilding the system files of the Garmin device

First, format the device with the computer in Fat. 32 type.

Disconnect the device from the computer and turn the device off and on.
After the device screen opens (FM Traffic provider database missing. Go to [Please Register or Login to download file] to download it.)
Confirm the notification on the screen (OK) and then the screen (YES) and connect the device to the computer.
Start the WebUpdater in the Garmin Express application and select the line (Reinstall the same version) and confirm the selections on the screen and start the installations.
Transfer the current map noref.php?url=https://www.freizeitkarte-osm.de/garmin/en/installation.html
either directly to the device or to the memory card and create a (Map) folder there.
Then check for updates with the Garmin Express application and install the updates if any.

Thanks for the link. I have actually managed to download (unzip etc etc) an image file that I have managed to put on an SD card and insert into the Garmin. That does give me a lot of map information but there is no PostCode search facility etc and its not as useful as the genuine Garmin maps. Is this link for UK&Ireland (looks like it might be for Germany?)? Thank you.

UPDATE: I did download, unzip etc and put it on a MicroSD card and, yes, ....it does at least give me maps I can use. (I'm still keen to try and resolved the actual Garmin issue though)

Make a copy of your Garmin folder and put it in my Drop folder
