Quick Question About Sat Antenna

Does it matter which way the sat antenna is facing? I mean, the rear of the antenna is where the line comes in so the opposite would be the front.

Due to lack of antenna wire provided, I have to mount my sat antenna on my front dash. When the front of the sat antenna is facing me, sat shows me parked facing the opposite direction. When I spun it around and pulled up and parked later on, I was facing the correct direction.

No, it doesn't matter.
As any GPS, IGO remembers the direction it was driving in. But the first (new) fix, it has no direction, so ...

Sometimes when Im stopped my Navi position moves around in circles.

As stated, no a problem.
