Altitude display says zero.....
Hello -- picked up my CDI on 3 July (still can't believe that vehicle in the driveway is MINE!).
I have the Navigation package, but when I show Compass on the COMAND display, the altitude always shows zero. Manual says it should be showing altitude, but does not seem to tell me what to do if it is not displaying properly.
Can anyone help?

It seems the altitude is calculated by the GPS location, not by an altimeter.
When you go to a mountainous area it will display altitude.

Keep in mind that there are very few hills in NJ except the western part of the state. Most all else is about sea level which would read 0.

Thanks everyone!!
The Manual says it should show from -328 ft to 19,680 ft (whew!).
Mine just says zero, both digitally and graphically--with 7 satellites. The elevation here should be pretty close to 131 ft (McGuire AFB runway elevation)
Obviously, no big deal--I imagine something was not initialized properly. If anyone thinks of something I can do, please let me know.
Course--this is also a great excuse to "make sure" by going on a road trip!!!

I do not believe that Mcguire's elevation is as high as you state. Even if it is the surrounding area could certainly be a lot less. I flew in and out of McGuire years ago doing military charters and I do not recall it being that high. In addition keep in mind that in most all aircraft with GPS the systems give altitude but in no way is the info accurate enough to allow you to use the info for flight purposes.

Get ahold of an approach plate, either Jeppeson or the Fed one and that will give you the airport elevation.

2006 ML-350 and 2007 ML-350
It could be just the nature of the beast. I've had a couple inexpensive Magellan units and the Roadmate 2000 altimeter was only accurate to within 100', yet the Roadmate 2200 is much more accurate (it seems to be within about 5' unless I'm inside my garage in which case it mysteriously starts "climbing"). Both of those Magellan units were tracking 20 satellites at the time.
