My radio/CD/bluetooth have not worked for a few months now and Ford will not cover under warranty. They stated the below part number would fix the problem. DG1T-19C107-CG I ordered this part and was sent the below part number. DG1T-19C107-DG is there a difference between the CG and the DG part numbers or are they the same? I hope someone can help me out. I dont want to install if these are not interchangeable. Thanks in advance.
