One of the most mind boggling things is why Japanese vehicles makers would put such a nice navigation system with no way of adjusting the clock or better still a language option.
This titorial is just to help people with hs309-a systems in their car atleast get some english notations. It still is very limited in its use as when you press on it, the next page will be in Japanese. Anyone who can help us get a boot sd card for this system with language option to English will be of great help!
