White arrow on screen ?

 

On the left side of my Nuvi 350 there is a white arrow. Can anyone tell me what is the little white arrow on the screen for? Sometimes it will be facing up, down left or right. Thanks a Lot.

That's the north arrow.

That's the north arrow. Take a closer look. It should have a little "N" in it.

Thanks Motorcycle Mama

Thanks Motorcycle Mama,
Guess I'll have to put my glasses on and check it out.
Thanks
