I just bought a '99 with a compass/altimeter/temp/baro. pressure thing mounted in the dash at the very top of the front center console. The thing is, it seems all out of whack. The compass appears to work OK but everything else (altimeter,temp, baro. pressure) are way off. I was wondering if there was some way to re-calibrate it. I don't know if it's factory or not but it looks like it is original to the car. Any thoughts on how to get this thing back to original working order? Thanks.

I'm not sure about your 99 but for my 02 wrx there is a way for the compass.

It consists of a button combo on the mirror followed by driving in slow circles. It was in the owners manual for my wrx.

Here's the procedure for compass calibration from my 02 wrx. ymmv

nCompass calibration
1. For optimum calibration, switch off all nonessential
electrical accessories (rear window defogger,
heater/air conditioning system, spotlight, etc.) and
ensure all doors are shut.
2. Drive to an open, level area away from large metallic
objects or structures and make certain the ignition
switch is in the “ON” position.
3. Press and hold the left button for 3 seconds then
release, and the compass will enter the calibration
mode. “CAL” and direction will be displayed.
4. Drive slowly in a circle until “CAL” disappears
from the display (about two or three circles).
5. The compass is now calibrated. Further calibration
is not required. The compass will automatically
calibrate from this point forward.

Thanks for the input, BUT....

as I said, the compass is the only thing that's actually working. It's the altimeter/Baro. pressure/temp that's not working. And the compass isn't in the mirror, but at the very top of the center console.

Are you comparing the barometric pressure against the current weather in you area? The altimeter is tied directly to the pressure reading and changes daily with the weather. I know the altitude of my driveway from gps readings so I recalibrate it with the altimeter +-buttons every morning while I'm waiting for the engine oil pressure to come up. That usually brings the barometric pressure reading close to what the weather report says.

The temp reading is somehow tied to the distance traveled or time I think so it may be off when you first crank up your car. Give it a mile or so to reset and see if it isn't closer to correct. The sensor placement has a lot to do with it too. It should be mounted in front of your radiator.
