Hi new to the board and Pioneer. I recently installed a X920BT and the when using the map screen the indicator (red triangle) is inaccurately displayed on the map. When I pull up to an intersection, it shows me on the map not quite at the intersection. When I turn, it looks like I'm turning into someone's front yard and then the map clicks and I on the street again. When traveling, I'm usually past a street or overpass before it shows on the map. I also noticed that sometimes it doesnt even show the surrounding street names. I moved the GPS antenna the roof of the vehicle about a week ag
