So when im going down a interstate a nice stright path the gps will not show a nice stright line instead it shows me leaving the interstate at random times so i end up with a zig zag line showing where i went.
I have it set to log every sec.
Is this casued by lack of signal?
I have tired WAAS and it did not make a differance so i assume its not getting a good signal. How many satellites should it be locked on to inorder to get better logging? Usally i get 6 or 8.
Is this the antenna that fits this gps?
