Citroen c5 radio and navigation problems

[Savo94]

I need an advice, I changed radio on my citroen c5 because the old one wasn't working and now i can't update maps on my navigation because i guess Vin number of my car isn't matching my new radio...
What should I do?

You need someone with a Diagbox to change the VIN in the radio head end.

I'm surprised that you haven't been prompted to do this before now by a persistent beeping indicating a mismatch between the VIN stored there and the one in the BSI.
