Pebble navigator shows you your speed, course and distance, direction and time to your destination. You can switch between compass and table mode by pressing SELECT button.
Setting your destination
There are several ways to set your destination:
1. In compass mode hold SELECT button. This will set your current location to your destination.
2. Through Google Maps "Share this place" function (you can get to it by holding finger on map).
3. Through 3rd party Android app via geo intent. Most apps call this something like "share location" or "display coordinates on map". I've tested with OsmAnd (free offline map viewer - pick your destination from map) and Tasker (Imagine possibilities. For example automatically setting destination to your car when you exit car mode.).

App shows weird values / Speed keeps dropping to zero / Values are jumping up and down. What is up with that?
At least on my Note 2, GPS works best when moving at relatively high constant speed. That means that bike and car works great, but not so much for walking, although it gets decent after giving it few minutes. It also helps a lot if phone is out of your pocket and has visibility of the sky (possible in car for example).
So if you experience weird speed, jumpy compass or just everything wrong try this:
1. Give phone few minutes, so it can get solid connection to GPS. Direct visibility of sky (outside your pocket) helps here a lot.
2. If you are still experiencing issue, get GPS Status app off market and compare values. If values are fine inside app, but only weird on Pebble, report that in this thread.
What is up with that experimental compass feature?
By default app only works using GPS. That is fine if you are constantly moving, buf if you want to stop and turn, app won't show that. In that case you can enable compass feature. Keep in mind two things:
1. It detects your orientation using gyroscope and you need to calibrate that. You do that by simply moving in straight direction with relatively high speed (over 3 km/h). After that you can stop and rotate around. Arrow should be pointing kinda approximately into proper direction (I said its experimental ;) ). Also if you move your phone (like taking it out of the pocket and putting it back in), you will have to recalibrate.
2. Some geniuses at Google thought it was good idea to shut down all sensors when screen is off. That means that compass feature only works when screen is on, thus phone won't let you turn screen off if you have that enabled. I don't think I need to tell you that this means huge battery drain.
Mainly due to second issue I probably won't develop this experimental feature much further. But I will probably wind up something when SDK for Pebble's sensors comes out.
