Some high-end GPS devices offer barometric pressure to obtain a measurement for elevation when signal reception is not very good. The result is that you will have a smoother elevation profile in the Dashboard and Map Player. Without an altimeter, the GPS assumes your elevation is not changing when the signal goes bad. This results in a blocky elevation profile. Soon MotionBased will verify your elevation with geo-coded data. So there will be no need for an altimeter.
