The manual sucks.
To my recollection there are a couple of ways to set up the appearance on the GPS
1. Use the Setup from the main menu or the "slide out menu" on the map screen. They give the same options. These are global appearance settings. Personally, I like the lane information. I think there is an option to "show audio information" too. Although I see no mention of that in the manual. It shows audio source info across the bottom of the map. I think it takes up too much room.
2. To do what you want: Use the right joystick to move through the "+" / "-", and "=" icons to get to either data field on the bottom.
Press and hold the right button for a couple of seconds and a menu will pop up letting you choose from a number of options like time remaining, distance remaining, time till arrival, speed, etc. I think the options for the left side are repeated for the right data field.
Hope this is helpful.
A lot of features on the Infotainment aren't exactly intuitive. I have the benefit of several months playing around.
