Hi guys, maybe an easy fix, but ill ask. When the nav screen is up, and tracking OK, Ill take a turn and the icon goes off the road???? 10-30 seconds later it jumps location back to the road and tracks OK until I turn again?????? easy fix???? any one with help???? I have had the Kenwood DDX 8017 with the Kenwood/Garmin nav and it tracked fine. Oh I have a brand new Avis N-1 with Sirus and steering wheel controls in a 2006 ford f350 SRW King Ranch with powerstroke DSL? Thanks, Patrick
