One of our customers has successfully updated his Opel/Vauxhall CD30/CD30 MP3 to CDC40 recently using the GM Tech 2 Scanner bought from obd2eshop. He did this because CD40 had a better sound output compared to CD30/CD30 MP3. Here obd2eshop would like to share his guide and help Opel owners to have advanced Audio display:

Replace the original antenna with the appropriate terminal for receiving digital signals:

To avoid replacing the entire cable I suggest you remove it from the antenna and then connect the old to the new
Connect to your CDC40 connecting the connector and the antenna wire.
Enter the CDC40 in his quarters, making sure that the connector wire remains free.
Turn the ignition on.
The CDC40 will turn on and begin to “bip”, the display will alternate “Display SAFE”, “Radio SAFE” and “UHP SAFE”.
