Good morning,
I had to replace the radio on my Jeep Cherokee with another identical but used one, because I can no longer view the navigator maps. Now, however, even if everything is working, it does not allow me to update the firmware and maps as it is associated with the vin of the previous car. I therefore ask if it was possible and with what procedure to access the internal program to possibly cancel this association. The radio is a Harman model CMC36670J.
Thank you in advance.
Joseph
