What Is The T0MYD Delphi Unit?
Delphi T0MYD Uconnect 5.0 / 8.4 Radio Code
The T0MYD is a Delphi-manufactured Uconnect head unit used across many FCA vehicles. It is commonly associated with
Uconnect 5.0,
Uconnect 8.4A, and
Uconnect 8.4AN Navigation systems depending on model and trim.
The radio serial number is printed on a white label on the radio chassis and begins with
T0MYD. The anti-theft unlock code is tied to that serial number and does not change.

Code Retrieval Methods
How To Retrieve A T0MYD Delphi Radio Code
The Dodge / Jeep / Chrysler / Ram Delphi T0MYD unlock code is tied to the radio serial number.
Most radio-code services use the serial from the label or Uconnect system screen to calculate the 4-digit anti-theft code.
Method 1
Check Uconnect settings
If the radio still allows menu access, look in Settings → System Information for the serial number.
Method 2
Read the radio label
Remove the radio and read the white label on the chassis. Look for a serial beginning with T0MYD.
Method 3
Enter the full serial
Type the complete T0MYD serial into the calculator above. Do not remove the prefix.
Method 4
Save your code
The unlock code does not change. Save it so you can reuse it after future battery disconnects.
Important: this calculator only supports Delphi T0MYD radios. If your serial starts with TM9, T00BE, TQN, Alpine,
Panasonic, Harman Becker, or another prefix, use the matching DUBB45 radio code calculator instead.
Free Uconnect Radio Unlock Code Online
When a Uconnect radio loses power, the anti-theft system may require a 4-digit unlock code before the radio,
navigation, Bluetooth, backup camera display, and audio controls work normally again.
This is common after a dead battery, battery replacement, radio removal, salvage radio installation, or dealership
module service. The code is not based on the VIN. It is calculated from the radio serial number.
This page is only for Delphi radios with serial numbers beginning with T0MYD. If your label shows TM9, T00BE,
TQN, Alpine, Panasonic, Harman Becker, or another serial prefix, use the correct calculator listed below.
