I have had this for 3 months, and I only I used it 2 times. Once when I first got it and once after a trip to the dealer for spark plugs. I am not going to be driving my car much in the winter time, so their is no point to keep it on the car. Everything is included, even the plastic screen cover. The AP is practically brand new and it will be un-married from my car and ready to be installed on a new car. All the newest maps are included.
