User Review: I received my Vista about two weeks ago and was excited to get it. After playing with the unit for about 30 minutes I was unable to get a satalite signal. Finally after I got in the middle of the field it picked up on 3 satalites. Thinking that this was a setup thing, proceeded to use the unit trailriding, in the car, walking around. Was pretty disappointed in the reception in all three places, satalite signal was being lost and accuired. One of the biggest disadvantages was if you have to turn on the unit close to trees it can't find a signal, even if the trees are 30 yards away and only 20 feet high and your standing in a opening.  Now other than reception this unit does have an easy to use interface with some really cool features like the altitude, time stopped, average speed etc. But to top off the review I think for the money this unit is not worth it. Garmin needs to rethink there reception issue big time. I sent the unit back and looking for a better one.
