newbie to site I have searched the web and this site but have not found the issue I am experiencing. The verbal navigation directions calls the 400 series of highways and others " H state route" for example "H state route 401"- "H state route 403. My dealership told me that is what Japanese made toyota cars, nav systems call the highways in Canada. I have asked if there is a nav software update as mine is 1.8.7 that might have been released to fix this issue. They said no.
