I am currently doing deliveries and purchased Garmin U.S.A. for iOS to use on my iPad Mini. Typically I will take 3 or 4 deliveries at a time. I would start my shift by entering an address to drive to for my first delivery and the Garmin app would display the driving map and directions. Then sometime later in my shift I would enter an address and would get the spoken directions but the screen would be white. This is problematic in the area where I deliver because of the way the roads twist and turn and change names for no apparent reason. The only solution is to restart the Garmin U.S.A. app and/or restart my iPad. This is very problematic on very busy nights and to be honest is not something I should have to do. I have uninstalled and reinstalled the Garmin app and its maps multiple times. I even did a complete backup and restore of my iPad Mini. Also doing a Google search on this issue it is not a new one for Garmin hardware and software.
