Had the z110 and never could get the turn by turn navigation to work. the voice never would get you past the first way point (flag). The icon keeps up with you on the map, but the voice and mileage indicator would stay with the first way point... After MANY calls with Pioneer tech, they told me it was a bad unit, so i returned it and even upgraded to the Z120BT! BUT it still does not do Turn By Turn... Same problem, just gets hung up on the first way point.

Mine doesn't show flags or way-points during navigation(only when approaching a turn within a mile)... How are you inputting your destinations?
