When using the "MAP" function many street names are not shown on the screen. Is there a way to update the system to show all the side streets, etc.?
I have the latest 2015 DVD but it seems the older disc showed these streets.

 

There's no update. Whatever is on the CD is all there is. Some times the side street names are out of view but will come and go as you drive, are you are zoomed to too far.
