Auto UnHide .System-folder

Garmin has made the file transfer for new 2012 Nüvi models like 24x5/25x5 saver. If you have one you probably end up here looking for a solution. The reason is that probably more people use information from sites like this, don't fully understand what they are doing and end up wrecking the nüvi because they deleted a important file.

The new behavior of the unit is that it represents itself to a computer connected by USB as a Media Device [portable device], meaning that it is not a removable storage device. The internal storage of the nüvi and the SD-card are sub folders of the media device. You may even disconnect the unit while it is transferring files, the nuvi is made Poka-yoke. The side effect of this is that it sometimes prevent the original MapUpdate included in LMT units to work properly or sometimes make you choose a smaller region. It is also difficult to make a full backup of ALL of of original files.

example for nuvi 2595LMT:


You probably have read this: [it explains why you cannot see or find gmapprom.img file in garmin folder]
[Only registered and activated users can see links. ]
What it don't like about this is that you have to change you windows-PC to show something on your nuvi, and then have to change it back because really, you don't want to see all hidden and system files on your computer.

Where going to change the nuvi:
1. turn the nüvi on
2. go to map page
3. press speed
4. press-and-hold the center of the speedometer for 10 sec.

[the are different ways to get in the Developers Screen, like the one in the link above]
5. go down to MTP settings [=Media Transfer Protocol]
6. check USB Mass Storage mode
7. turn the nüvi off
8. connect to USB
9. The internal storage of the nüvi and the SD-card are shown as separate portable storage device.

Important: it is not a Media Device anymore. But if you are confident that you do not delete any files accidentally you can leave the nuvi in this mode forever.

Now we put al little script on the nüvi [the main reason for this post] because the .system-folder is not visible.

Create an empty text file [or just get the zip-file] and put the cmd-script in the root-folder of you nüvi. [Only registered and activated users can see links. ]

UnHide.System.cmd

Now double-click it and after the refresh the hidden .System folder is visible on your Windows screen. You don't need a hide script, after you unplug it from the USB the nüvi changes the folder attributes. For this it is best to leave the script-file on the nüvi and run it every time you need to UnHide and look into the .System folder. After all, you probably need to access it only a few times a year.
Now that it works, make sure you make a full backup copy to you harddrive [I always use a 7z-archive]
If in the future your MapUpdater forces you to select a smaller mapregion, just run the script, go to .System, delete the gmapprom.img file and try again.
