Compass and Elevation Function: Do any GPS units have a compass and/or elevation (altitude) function?

Press the signal bars in upper left corner and you can check the Satellite signals and elevation is also displayed.

The accuracy of the unit is 2.5m 2D rms, altitude is a little bit less accurate, typically around 3-5 meters. It will depend on the GPS signal quality and DOP numbers. You can use the UltiMate GPS app to determine the accuracy: press on the "i" button and it will come up with a screen that has DOP numbers and the accuracy that goes with them.Roger Koumans, Emprum LLC

Yes, you need to know the GPS coordinates of your destination. There is a small arrow that appears on the screen indicating what direction the location is. I use this Garmin exclusively for fishing ocean wrecks and it has spot on accuracy.

You can download GPX files of routes for hiking and biking. Also some maps that you can purchase have these routes printed on them. Yes the GPS does show your elevation very accurately. I have compared it to the elevation markers at the top of hikes and it is within a few feet.

No, it gives you the compass bearing and distance from your selected base and waypoints. It does that quite well.

Yes. The sensor will gives you latitude, longitude,altitude, speed, heading, climb rate, time on my raspberry pi.

Yes it does. Just checked it out. There is a window in the lower left corner of the screen which can display time of day, altitude, or direction of travel. Just touch that window and you can select the options.

It does but it's a little flakey, and that's with good satellite coverage. GPS' just don't work so great when it comes to elevation. The 305 does work 'good enough' though. I do all my runs on mountains so elevation and grades are very important factors. I'm satisfied enough.

Hi Ghalib, this GPS device by itself can report your speed, the direction you're going and your height above sea level, but the real genius of this device becomes apparent when you pair it with an iPad or iPhone for navigation. When there is no cellular network to tell your phone/tablet where you are, like when you are in a remote location or at high altitudes like flying in a plane, this device tells your mobile devices where you are. The other time you might not have a cellular network is if you are traveling abroad and you turn roaming off to avoid data charges on your plan that can amount to hundreds or thousands of dollars in roaming charges.

Magnets are no good for compasses not gps. GPS uses satalites which has no nothing to do with magnetic north.

This is just the GPS signal receiver, not a complete GPS unit. It works well, but specific features such as altimeter readings are going to depend on which iPod app you use. Many people end up using several apps, depending on need. I use Gaia w/ USGS topo maps loaded, which of course give altitude readings with the topo lines. The basic app that comes with the UltiMate gives speed and altitude readings, although I have no way of knowing how accurate they are.

It has GPS, but most people found the software implementation to be seriously lacking. It takes a while to update your position. I've read that this has been fixed in the FroYo pre-release that was leaked, though, so it may be better once the official release hits in September.

As a genral GPS unit. It does give you a way back by reversing the route. I've never used it that way.

There is a "Maps" app that comes installed. If you allow it to do so, (and you have Wi-Fi or a data connection) it will show you where you are and give directions to a destination. It doesn't actually give the GPS coordinates but there is an app for that too (I use "My Altitude").

Yes, it does track elevation. I'm not sure if you can view elevation info on the watch itself, but once you upload the run data into something like Garmin Connect or Strava you will be able to see elevation gain and an elevation graph.

Sort of. It works for tracking and elevation. However it doesn't come with any topographic or trail maps. You will need to load maps if you intend to use them, which you probably do. There are free maps available to download online. I think the best site is GPS File Depot.

Altitude or more specifically elevation is recorded and reviewable once uploaded to your computer via MySports but you cannot see this measurement on the watch's screen. I am sure if there was enough demand, the engineers at TomTom could program the watch to display it.
