The Test Mode, also known as the secret menu, gives access to various developers features, but is commonly used for accessing MICOM Manager or the underlying operating system, Windows CE (on first and second generation Media Nav units, MN1 & MN2).
Step 1. Go to Settings > System > System Version.
Step 2. Touch the screen 5 times, according to the pattern (press in the order of the blue bullets):
For MN1 & MN2:
Text alternative: System version – Next to back arrow – Next to clock – Below top bar, in the middle – Bottom-right corner.
For MN3 & MN4:
Text alternative: Below System version – Next to back arrow – Below clock – Below top bar, in the middle – Bottom-right corner.
At this point, the Test Mode should be shown.
The simplest code to test is for the Version info, which displays a handful of version numbers for hardware and software, useful for debugging purposes:
|MN Version||Firmware Version||Code|
|MN1 & MN2||ALL (1.0.2 – 9.1.3)||1111|
Simply enter the 4 digits and press OK. The Version info dialog will show up.
Note: You can get the codes for all MN3 firmware versions by using the Test Mode Codes Tools (MN3).
