We ran the update as the vehicle requested, and ever since then the navigation system (more times than not) often doesn’t seem to know where we are. It is inacurate, even shows us driving thru lakes, etc. Sometimes, after about 15 minutes to 1/2 hour it will figure out where we are & correct itself. Doesn’t seem to be any rhyme or reason as to when it is wrong.
2 year old car still under warranty, isn’t it? Take it to the dealer.
