I know it's a small problem, but I would just like to have everything working the way it should. On the MMCS under the Environment option, my altimeter is usually 150-200 feet higher than it should be. I'll be parked at the beach and it will say about 150 feet which I know is incorrect because I'm 10 feet away from the ocean.

I brought it to the dealership and said there should be a way to calibrate it, anybody have any ideas on how to do so?

 

from the set button, there should be an environment area. i believe the calibration is within this menu.

 

There's no options within the environment tab. Is there any like way to reset it maybe?
