GMC Troubleshooting Questions? Ask a Mechanic for Answers
I am sorry for the long wait
is this a new or used radio you have installed in this Suburban ?
ok thank you for that information
please do not shoot the messenger here as it is something you do not want to hear
since late 2004 range GM stopped using the unlock code numbers to unlock these radios and have evolved to the radio theft being activated if the VIN number programmed into the radio does NOT match the vehicle the used radio was installed into
the only way to unlock this used radio is a shop with programming capabilities must reprogram the radio and set up with a programming scan tool to the trucks VIN number it is installed into.once that is done the radio will work just fine
I wish i had something quick you could do to unlock the radio but GM has tied everyone's hands as only programming the radio will make the used radio operational
this question shows a fee of $ 26 dollars from what i can see on my end
you choose to not rate or except the answer ?
