Test Mode Codes Tools (MN3)

Like on previous generations, third generation Media Nav units have different Test Mode codes for each version. The only notable difference is the larger number of versions and releases, each with its set of codes. In order to find some of them, specifically the code that unlocks extended codes, the MICOM Manager code and the version info code, we have 2 ways: either calculate them using a small tool (only for Windows) or retrieve them from the Media Nav unit itself.

How to use

MN3 Codes Calculator

Step 1. If you don’t know it, get the complete firmware version using this tutorial: Get the complete firmware version (MN3).

Step 2. Download MN3 Codes Calculator from the link in the table above.

Step 3. Unzip the archive and run mn3_codes_calculator.exe.

Step 4. Write the complete version of your Media Nav firmware in the text box. Examples: 1.0.13.1.366_r36, 1.0.13.3.369_r60, 2.0.9.9.464_r23 etc.

There will be 3 codes calculated automatically:

MN3 Get Codes

Prerequisites:
– a tablet, laptop or desktop equipped with an USB port
– USB flash drive, FAT32 formatted, max. 32 GB capacity, ideally with an indicator light

Note: An USB flash drive with an indicator light is preferred since the light will be the only indicator of the ongoing read and write operations performed on the flash drive.

Step 1. Download MN3 Get Codes from the link in the table above.

Step 2. Unzip the archive and copy the folders to the root of the flash drive – the folders should be the first to be seen upon accessing the flash drive.

Step 3. Put the flash drive in the USB port, turn the Media Nav on, wait for it to boot and the backup will start automatically.

Step 4. When the indicator light of the flash drive stops blinking for 10-15 seconds or, if there is no indicator light, after about 1 minute, you can unplug the flash drive and turn off the Media Nav.

Step 5. At this point, a file named config_log.txt can be found on the flash drive and it contains the 3 codes, PW1, PW2 and PW3, in an encoded format, like 564d0100040034363230154d42b5 or 564d0100040030363838faba14ce. To decode it, take the group from the 13th to the 20th character and remove the 3s. Example: 564d0100040034363230154d42b5 > 564d 0100 0400 3436 3230 154d 42b5 > 4620.

The 3 codes that result after the steps above will be:
– PW1: the code that unlocks extended codes;
– PW2: the code that opens the MICOM Manager;
– PW3: the code for version info.
