I recently installed the mygig v.2 lockpick and rearview cam in my nav equipt 09 sahara. I was trail riding in the woods today and noticed the GPS thought I was driving in reverse when I was cruising forward. Everything was moving opposite. I figured it needed to be recalibrated or something and left it alone. BUT, after stopping for a minute to take a woods rest stop, I noticed it was working again???? We headed out onto a local road and the nav was now moving in the correct direction but noticably 'off'. It was showing an me in the middle of and intersection after it was 50 feet behind me??? After stopping again and keying off and on, it was reversed again??? WTF. Any suggestions. Everything on the mygig lockpick works as advertised buy my nav is now fubared a bit. Do these calibrate somehow?
