Many of you may have already figured this out, but as there are also quite a few comments relating to the way the accessory "widgets" that appear to the right of the speed in the cockpit panel (e.g. nav guidance, current song, etc.) when in the Home tab, I figured I would share my analysis and theory. From what I can tell, the pilot panel and cockpit panel are basically completely separate devices, like having two iPads on your desk, not like a single computer with two displays. You can run the nav app, and the music app on both, but they're completely different instances of the app. Clearly they are sharing some information because when things are working right you don't have to enter an address twice, but note that they do not appear to "launch" in the background if they haven't been selected, which results in the widgets not appearing consistently in the Home tab in the cockpit panel. In addition, the nav, music, and phone views displayed in the "Home" tab are NOT the same as the full apps.
For example, if you startup the car and the cockpit panel is in the home view, and the pilot panel is used to select nav and enter an address the map in the Home tab of the Cockpit panel does show the directions, however no details will appear next to the speedometer. If you select the nav tab in the cockpit panel, you see the "Gravity" loading screen and then the nav appears, and NOW if you switch back to Home you will get the directions... Music is the same. Hopefully in a future update they will auto launch all the apps (there's not that many!) on both "devices" at the same time so you don't have this weird scenario where they're out of sync.
