3. the following uses key cracking and installs the map on SD as an example.

 

1. Turn on GPS: Main Screen point tool → settings → system → about, copy the local ID (usually 10 digits) and connect the GPS to the computer with the data cable
2. If the map is mounted to the SD card, you need to rename gmaprom. IMG to gmapsupp. IMG, and then copy gmapsupp. IMG and JCV to the Garmin directory of the SD card (overwrite the original gmapsupp. IMG)
3. Use the key tool and the local ID code to generate a cracked decoding and use the cracked decoding tool to create the gmapsupp. unl file.
4. Create a gmapsupp. unl file in the gamrmin directory of the SD card (the same directory as gmapsupp. IMG)
5. Copy gmapbmap. IMG to the local system directory. System (Hidden directory ).
6. Copy gmapsupp. unl to the local system directory. System
7. Shutdown, boot OK!

 

Note:

A map does not need to be cracked. The so-called decoding method is a set of codes generated for its own IDs. This encoding is used to ensure that the same map cannot be used on different machines. That is to say, the encoding will be checked when the map is started. whether it is generated by the local ID

This prevents pirated maps from being copied through SD.
