Hello. Realised my old thread was very unclear. So Will try to be more precise.

How do I and what tools do I need to buy to reprogram
an v70 02 dash to work in a s60 02 car. In the easiest
Cheepest way. I'm a total beginner, but want to learn how to do this kind of repair. So would love if there are several different methods and tools.

God evening // Casper
