Usually for the first 2 minutes after turning on the car, I find that the nav is off by atleast 100 feet, it often has me off of the roads. I also find that when I deviate off of a set route in the nav feature, the arrow does not follow my new route for atleast 20 seconds or so. I think this also happens when I am just watching the screen w/ no destination set - My antenna is on my dash and I usually have all but one satallite available.
Anyone know why this happens?
Otherwise, I havent found any missing location data but i have found the nav unit to give poor directions when it comes to
