Nissan Repair Questions? Ask a Mechanic for Answers ASAP
The wrong code has been entered into the unit three time and so the unit is then ocked for an hour. I think you can enter the code wrong twice more and then the unit is locked and requires replacement!
You need to visit your local Nissan Dealer who will take the details off the radio. It will make it easier for them if you just show them that photo because that is the details they require!
They can then apply to Nissan Technical for the correct Radio Code for the unit. There is usually a charge for this or approx £30.
