I don't know how many contacts I have on my iPhone - maybe 250? I do know that it takes about 2 minutes to fully sync them to the car before you can use them. What is REALLY frustrating, is they show and you can select them, but just when you are about to hit dial (or do this with voice commands), the list disappears as it is updated. THEN it happens again. Very annoying, but I don't see a way around this. Maybe IOS 6?
