Search for european firmware

If the car was bought and not stolen, the seller - or a Toyota dealer - should be able to set the correct language.

 

I assumed this is a used Japanese car, imported privately. The seller was probably an auction in Japan (or a local importer), and the local Toyota dealers will want nothing to do with this (they may do normal servicing but are not obliged to - not sure what they're like in Russia).

Unfortunately it's not just about changing a setting - from what I've seen with JDM models they're in Japanese and can't be changed without modification. I've seen Japanese imports in the UK which somehow have instrument clusters in English, but I don't know how they did this. There may be some way of flashing the firmware, or they may be changing out the unit entirely (e.g. from crashed European RHD models).

We get a lot of used Japanese imports here in Ireland - it makes a bit more sense for us as we drive on the left too But there are risks involved in that after-sales support will be poor to non-existent, the main dealers may not want to touch the thing (they may do "best effort" technical support, but I've heard reports of JDM cars not working with dealer diagnostics equipment, etc.), and getting parts can be tricky if they differ from local versions of the car.
