Hello Frederick Dallas.
It appears a side-trip thru Micro-Soft is required.
Gathers Memory Navi Honda Genuine OP VXM-090CV... seems to resolve to a NENGUN Company.
My first inclination was to learn Japanese... but I'm old (not enough road nor time & too many other interesting things)
The following "comforting" statement ... on the CORPORATE HELP WEBSITE (http://www.nengun.com/help/website.)... says:
Even if you can't read Japanese, it is preferable to see the actual Japanese characters than invalid characters, often shown as black boxes.
Black Boxes or Japanese are pretty much the same to me (Perhaps the Japanese "MENU" icon ... is flashing green).
If you are using Microsoft Windows this can be "easily" fixed by downloading and installing the free Japanese Language pack from Microsoft.
Hopefully this "EASY" stuff on their website... comforts you better in ENGLISH.
Good luck with that.
Go to... Japanese Language pack from Microsoft:
