I have a Garmin 2447LM.
I made the change to Windows Explorer to show hidden files.
But when I connect my GPS, I do not see hidden files and folders.
So I can not delete the old card to update the map.
Can you help me?

Best Regards,

I found the solution to my problem

Can't see a .system folder!!


The .system folder is on most newer devices. Older devices do not have such a folder.
There are several reasons why you may not be able to see the folder in Windows Explorer.
1. Your folder settings may not allow you to see it. You should follow the instructions in
Beginners Education 1 - Get Manual; Verify PC Settings; Setup POI Loader (Garmin) | POI Factory
to make sure your folder setting are correct for such work.

2. You are not in Mass Storage (MS) mode but are in Media Transfer Protocal (MTP) mode. To change to MS mode
A. Start NUVI by itself and go to Volume Screen.
B. Press the upper right hand corner of screen for 10 seconds.
C. The Developers Screen will pop up
D. Scroll down to MTP SETTINGS
E. Change from AUTO DETECT to MASS STORAGE
F. Shut down NUVI and hookup to Computer USB cable
G. The computer should recognize it is hooked up to the computer.
H. Explorer will now see all files in ROOT directory and the .System directories.

or perhaps
In the map, touch the speed to get to the dashboard screen.
Touch the speedometer for a few seconds (about 5).
As above, scroll down to the MTP setting and select Mass Storage.

Note: if you are in MTP mode (newer models only), your device will look different in Windows Explorer. It will not be assigned a "drive" letter and will contain "internal storage" at the first level of expansion.

Also, when you connect your MTP device to your computer, the Icon will be in color on the front of the device. If it is in MS mode, the icon will be in white.
