Garmin Etrex Vista Cx

Tried my almost new but nearly obsolete Garmin Etrex Vista Cx on a flight to PHX today.

The Vista Cx is being replaced by a more sensitive model with poorer battery life by Garmin.
(See May 31st 2007 press release titled Garmin Adds High Sensitivity GPS Receiver to eTrex® Series here.)

I can confirm it cannot pick up satellites inside the aircraft (A-320) unless it's placed right next to the window, as shown above. The window shade and the rubberized case cooperate nicely. Then it happily tracks the flight. I wonder how much better the model with the newer chipset performs.

[I turned on the GPS somewhere before the plane got near Chicago and turned it off shortly before landing at Phoenix.]

Since the Vista Cx also has a barometer, it is fooled by the cabin pressure to report (incorrectly) merely a mile-high altitude. However, the location seems correct, as the map features seem to match up perfectly with what I saw outside the window.

  1. Obsolete? I am still able to use an almost 10 yr old Garmin Emap if I wish.

    I am happy with the eTrex Vista cX though. It will make a very good touring aid.

    Give us a report when you upgrade;-)
