The RCD 300 unit is commonly found in Volkswagen Golf, Passat, Touran, Polo, Caddy and other VW models. After a flat battery, radio removal or electrical repair, the unit may lock and ask for the original code.

If the sticker is hard to read, take a clear photo before submitting the request.
Why is my RCD 300 asking for a code?
The Volkswagen RCD 300 has an anti-theft security system. When the battery is disconnected, replaced or completely flat, the radio can lose power and enter SAFE mode.
This can also happen after the radio has been removed from the dashboard, replaced with another unit, or after work has been done on the car’s electrical system.
Once the RCD 300 is locked, it will not play audio until the correct radio code is entered. Random codes should not be tried, because too many wrong attempts can make the unit wait longer before another attempt is allowed.

How the VW RCD 300 code process works
1. Find the serial
Remove the radio carefully and read the VWZ serial number from the label.
2. Submit the request
Enter the serial number in the code search form and complete the secure checkout.
3. Receive the code
The RCD 300 radio code is sent by email once it has been generated.
How to enter the RCD 300 radio code
Switch the radio on and wait until the code entry screen appears. Use the preset buttons to enter the four-digit code. On many VW units, each button changes the digit shown on the screen.
After the correct code is displayed, confirm it using the radio button combination required by your unit. If the radio is still showing SAFE, leave it powered on and wait until it allows another attempt.
Before you request your code
Please check the serial number carefully before placing your order. On RCD 300 radios, similar characters can sometimes be confused, especially when the label is old or scratched.
Common mistakes include mixing up 0 and O, 1 and I, or missing one character from the end of the VWZ serial. The code is generated from the radio information, so the serial must be correct.
