As said above.
The jap system is utterly useless in the UK. No way around that.
My suggestion would be to remove the entire system and skip it. You can then get one of the systems built by "Cookbot" or Nurrish" who are members here.
Failing that, you can slot a TomTom or the like into the cubby.
You would need to buy a OEM cubby to replace the Jap System if you removed it.
