Can I upgrade my Mokka's stereo?
Hi I have. 2015 mokka elite 1.4, with a cd 600, I’m looking at updating/updating it to a Navi 900....can this be done ??? If so what will I need to change, how much??
Our answer:
Hi Matthew,
It might be technically feasible, but it is not an easy change and one that an Opel dealer is unlikely to want to get involved with. No harm popping in to see them to talk it through, though.
