My country's market is dominated by second-hand Japanese imports, a lot of the integrated navigation / entertainment systems are entirely useless if you're not driving in Japan, or can't read Japanese.

When my 2005 Mazda MPV suffered a flat battery, the centre console screen which was the navigation / radio / clock / DVD player (yes, really) was bricked, and to this day displays a message in Japanese asking you to please insert the manufacturer's navigation data CD to continue using it.

Which no-one has access to, not even in Japan (my brother has been living there for about ten years, and is very helpful for obscure parts requests), so now my radio and clock don't work, because I don't have a CD with data needed for a 16 year old navigation system that, when working, was thoroughly convinced I was driving long distances on the bottom of Tokyo Bay and was desperate for me to turn right and get back on dry land.
