How to Check the AVN Head Unit When Replacing It (Variant Coding)
The AVN head unit performs basic audio, video and navigation functions.
It also receives overall information about the vehicle from other units (SWRC, FATC, BCM, PGS, AVM, Cluster, TMU, ECS, etc.) through CAN communication and forwards it to the driver.
Thus, when replacing the AVN head unit, be sure to enter detailed option information of each vehicle model into the new AVN unit for proper operation of AVN system.
This process is called variant coding.
The following process describes the GDS based input method only.
Check the options installed on the vehicle before proceeding to the AVN head unit variant coding.
Select a vehicle and then select "variant coding", an additional function of the AVN head unit.
Set up the options installed on vehicles.
If you input the wrong variant, the AVN head unit will not work correctly.
After replacing the head unit, set the replacement, stop the engine, and close and lock the door. Do not operate the car for at least three minutes to save what has been coded.
The code is saved in the head unit only when the AVN system completely shuts down and then wakes up.
Follow the guidance of on-screen information and stand by. Wait until it is completely saved and then exit.
