These are the easiest ways to locate it:

To find the serial number, you'll need to remove the radio 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 label on the side of the radio. Be careful not to damage the cables.
- Write down full serial number carefully and then come back to the website.
- Know that serial number and part number are not the same. You can find both of them on the unit, and you only care for the first one.
