Hello,
Every Renault Car has unique Authentication Key
You may contact in your Renault Dealer and share in
> Engine Number
> Chassis Number
so that they can punch this in system and can provide you Media Nav Authentication Key
Even - you can check in Media Navigation Manual - if the dealer has mentioned Radio Code in it at the time of taking delivery, if not may have to approach in Service center for same and note down this unique 4 digit authentication Key of Music System
Hope should help !!
