Looks like Toyota provides Audio Multimedia System Updates (firmware updates/patches) for limited models, link below.
 

Has anyone done the same downloading JDM  updates? Might need VPN and/or give Japanese chassis number? Wonder if Chris might have come across?

Doesn't appear to offer Alphards or Vellfires, possible as they are grey imports.

That's why I'm thinking jdm market might be getting these if we have the VPN and chassis number ready. I might ask for help to some Japanese professor I know as this might need language 

I wonder if anyone found something.

I was wondering if the imported cars' systems can be upgraded via a download from the Toyota Japan website.
