Lately, my D3 in my truck has been really letting me down. So much so that I have had to bring my Tom Tom with me as back up. I always keep the map displayed as I drive. When I am driving, I like to keep the map display in a way that the arrow is always pointing up. Lately, the arrow has benn pointing sidesways while I am moving. It is really annoying. Sometimes the arrow will be off track. For instance, if I am driving on the highway, the arrow will be on the side road. I've tried resetting, I've tried relearning as well. There will be times of clarity. The other day I travelled from Houston to Dallas. I plotted my course and took off. While on the way, the Avic would inadvertantly move to the side road, and it thinks I am off course. Why does this happen?
I've attached a photo I took when the arrow wasn't straight.
