| 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.
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.
|
The following process describes the GDS based input method only. |
| 1. |
Check the options installed on the vehicle before proceeding to the AVN head unit variant coding. |
| 2. |
Select a vehicle and then select "variant coding", an additional function of the AVN head unit. |
| 3. |
Select the options installed for the vehicle.
|
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. |
|
| 4. |
Follow the on-screen information and standby. Wait until it has completely saved and then exit. |
