I have an N1 that I got years ago that I just recently replaced with a 700bt. The reason I replaced it was because the touch screen was having the same issue I have seen listed here many times in that the left side of the screen is off by a half inch. I tried the service menu but it seems that something needs to be replaced and its not just the setting. I think its the actual touch sensor assembly csx1083 but before I spend the 70 bucks on the part I wanted to see if anyone has fixxed the issue going this route or if maybe pioneer replaced this piece to fix the issue or if it is another piece
