Ok just installed my D2.. and was driving down the road and the arrow is pointing the wrong direction (looks like im driving sideways). Does the Antenna need to be pointing a certain direction...i tried to move the antenna so that it was pointing a different way but still the same problem...and suggestions...thanks in advance...you guys have been great so far!!!

Ok figured it out....thanks though

So what was the problem. Please share in case I come across this problem when I do my install.

Oh the problem was not with the gps antenna....had to go into the the navigation settings and hit the recalibration button...it resets the sensors or something...probably wouldn't happen to you...I bought mine second hand from someone on ebay
