Recently I bought a second hand Japanese toyota chr which is almost new and am very happy with it. The only issue I have is that I would like to change the audio unit of it since it is mainly in Japanese and I cannot make it function well. I was wondering if I manage to buy a second hand one from a European car that maybe is a write off, if it would fit in my car. Or if somebody changed it and can give me some ideas since I have been searching but did not find something to my like. Thanks.
