CMax Key Code

To enable your CMax account you must obtain a key code. The key code is generated from your Avidyne MFD serial number and your Jeppesen Software Serial Number.

To obtain your Jeppesen Software Serial Number, contact Jeppesen at 1-800-621-5377.

Enter both serial numbers below and press Get Code. Enter your Jeppesen Software Serial Number without dashes or spaces — it is case-sensitive, so enter it exactly as issued by Jeppesen.

If your CMax Key Code begins with #, be sure to include that symbol when entering the key.
