I recently switched from a Droid Razr Maxx to the Samsung Galaxy S4. I purchased the car dock for the new phone because I used my Razr everyday when I drive to work to look for traffic jams and avoid sitting in traffic. At first, I did not find the Car Dock application on the Galaxy S4 so I downloaded the Car Home Ultra app from the Google Play. When using Maps through the Car Home Ultra the screen dims after 30 seconds then timesout after a minute. My display timeout is 1 minute but it I never had this issue with the Razr. When using Maps or Navigation while in the car dock the screen display never timed out as long as the device was plugged into a power source. I did notice that the display did remain on when it was on the car dock home page, but not when I selected one of the apps from the home page.
