I have the same problem, bought my Forester in December and immediately called to get the free update. I was told the same thing. I figured that since the motorhome was new the information was the latest, so did not pursue the issue.
Don't mean to hi jack your post, but I have a problem, the estimated time of arrival is not accurate. At times it can be 2 or more hours off. This can be very annoying when planning a trip. Has anyone else had this problem? I thought maybe an update would fix the problem, but have not been able to get an answer from the manufacturer.
