I told the dealer what happened and they got approval to get the new SD card. Since then the NAV has been spot on. Every bit as good as the top end Garmin that my wife uses in her 2006 car that does not have built in NAV.

My car was built 03/2013 and the NAV so far has worked great. Much better than my 3 year old Garmin Navi. I was expecting much worse.
