DAMN IT I NEED ONE!!
It appears the navigation system (screen in dash) is not available outside the JDM. So it probably isn't available in a version for RHD. That hasn't stopped some (at least one) people from adding their own in a similar location.
There actually is a great amount of room behind that spot in the dash (enough for a full din chasis IVA C800)... but if you merely want to mount a navigation monitor, there's a ton of room. A good installer should have no problem. Plus, a replacement dash is only ~$340 so if you mess up, just get another one...
Someone should to some research on the system. The GPS satellites are the same. The bezel looks symmetric. I would assume the module is the same as the acura, which has a US DVD. It looks identical to my MDX nav unit, but smaller (about the size as the rest of the acura line). All of the software for the system should be on the DVD making it possible to upgrade by changing DVDs.





I just couldn't resist.
