I bought the 5x and tested it on vacation in Utah. The compass was stuck at SW no matter which way I turned. I recalibrated and it worked. Next day, same thing, stuck. Recalibrated and it worked. I repeated this process the entire vacation, frustrating. I drove 2.5 hrs highway, when I stopped I noticed 4000 steps? I rolled out of bed and got on the road! Maybe 200-300 max, not 4000! The altimeter, I calibrated several times. A sign right by my camp told me my altitude and I calibrated to that which happened to be with in 10 feet of my Apple phone calculation. Next day, 300 feet off. Recalibrated, next day 500 feet off? Realibrate drive up the tunnel which is 11,300, watch says 10,100.
The mapping worked fine but man, that?s some serious problems with a 700.00 smart watch. I took it back as soon as I got home but I really wanted the watch to work out. The mapping was just to hard for me to deal with so now I?m thinking should I try a 3HR but I?m nervous I?d have the same issues. Anyone else have all these issues?
