Do they announce it anywhere, maybe a website or should I just check with the dealer around the end of the month. another thing I was wondering is that if they did not change anything from last years dvd to this years in my area, I would probably be fine with last years and get the updated dvd now. Do they list anywhere what they are changing? (my home and the freeway I drive the most is not currently in my nav dvd so I am a little impatient). Thanks again, Don
