How to Find the S/N on a Radio
The only thing you'll need to find the corresponding code is your radio's radio serial. VIN or other details are not required.
On almost all Hyundai vehicles, you can find it in one of these places:
- Visible on the radio screen (sometimes by using specific button presses)
- On the radio housing itself - you'll need to pull it out and write down serial (which is usually simple)
Search for text similar to: Serial Number or SN.
1. Displaying the Serial Number on the Veloster Screen
Hyundai Veloster radio does not display the serial number on the screen.
Unfortunately, the unit must then be physically removed to find the serial on a factory sticker on the radio casing.
2. The Serial Number on the Radio Label
To find the serial number, you'll need to take out the head unit from the dashboard.
- Start by turning off the vehicle and taking off the dashboard bezel.
- Next, release the clips and slide the radio out to check the sticker on the side of the radio. Pay attention not to damage the cables.
- Write down the serial number precisely and come back to our website.
- Know that serial number and part number are not the same thing. You will find both on the sticker, and you only need for the serial.
