Wait a minute, perhaps we were thrown off by the Harman Kardon. I searched for just Harman Navigation System and found this >>>LINK<<<. It's a Samsung company, specializing in Intelligent Navigation. That would make more sense given the connection to a Japanese production. If you search Harman Navigation, there are a lot of references and material, including some good YouTube videos about what Harman believes their role is in the "Connected Car".
This may be a signal that Honda, like many of us, is fed-up with Garmin's approach to navigation systems.
Harman makes the Aha app for the HondaLink system in Honda cars. They already have a relationship with them.
