How do I keep it on the Audio display, or show both at the same time (Nav and Radio) like all other cars? Plus how do I re-center the map if I accidently press one of the areas on the screen?
Haven't figured out a way to keep audio only on screen without reverting to the map but on my ATP Prius I can do the map & audio by pressing the "Map mode" button and then choosing map & audio mode To recenter the map if you move it around, press the physical "Map" button (same button you would push if you were on the audio or app screen and want to switch back to the map sooner than the normal timeout revert back to map)
On the 2010 Nav you go to Settings -> Nav -> Auto Screen Change and change from On to Off. The default setting is On which automatically switches the screen back to the Map. The Off setting keeps the display on the last setting. To re-center the screen I believe you just hit the Map button.
