Where to Search for the Serial No.
To get the correct radio code, you first need the radio serial number.
Depending on your radio model, you can find it shown on the display or locate it on the unit.
It's often written as: S/N / SN / Serial / Serial Num. / Serial Number.
These are the typical ways to get it:
1. Getting Touareg's S/N on the Screen
The vehicle is fitted with VAG-group radios such as the RCD 300, RCD 310, RCD 500, RNS 310, and RNS 510. None of these units support an on-screen serial display. You will need to remove the radio to find the label.
2. Locating your Serial Number on the Radio Unit
To find the serial number, you'll need to pull out the head unit out.
- Start by turning off the vehicle and taking off the dashboard bezel.
- Next, release the clips and pull the unit forward to check the sticker on the side of the radio. Be careful not to damage the cables.
- Write down full serial number precisely 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 sticker, and you only care for the serial.
How to Pull the Radio Using VAG Keys
Standard VAG removal keys (two per side, inserted into the round holes flanking the unit) are the only safe way to extract the radio. Push them in until the retaining clips release, then slide the radio out. The serial label will be visible on the back of the unit.
