The CMax KeyCode generator is attached to this knowledge based article, for those pilots wanting to create their own code. See Note below.

 

To find the Jeppesen 16-digit Serial Number for the charts, please login to your JDM account.
Find the EX5000 (EX500/EX600) charts.
At the end of the EX5000 charts line, click on (MORE...).  - this opens a pop up window.
At the bottom of that pop-up window, click on Set your Avidyne CMax Key Code. - this opens a new pop-up.
At the bottom of that pop-up, do you have a CMax in the appropriate field? (take a photo)

You can copy the 16-digit serial number from the last window, paste into Notepad, this helps to strip any formatting.

Get the MFD serial Number off the Aux tab on the MFD. - this should be 8 digits, and should not be FLIGHTMAX (take a photo)

If your CMax is missing, I can generate you one; requires the JDM 16-digit account number and your MFD Serial number (found on the Aux tab).

**January2022-UPDATE** if your generated CMax key code has comma's (see example below), this is invalid. Use the attached AviUtility.exe to generate a valid CMax.
