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, Cubis T, ECS, etc.) through CAN communication and forwards it to the driver.
Therefore, when replacing the AVN head unit, you must input into the unit the detailed installation option information on the vehicle to correctly use the device.
This learning process is called variant coding.
NOTE:
- The following process describes the GDS based input method only.
CAUTION:
The code is saved in the head unit only when the AVN system completely shuts down and then wakes up.
- 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.
NOTE:
- Check the options installed on the vehicle before proceeding to the AVN head unit variant coding.
- Perform the variant coding procedures as shown below.
