I am sooo frustrated with the inaccuracy of these nav discs. I have owned the N1-N3, and never had this problem. I also had the Avic D2 before I bought the new D3 this year. Has anyone else had this problem? I had a conference to go to in Mobile, AL earlier this year, and the Nav dics was about a mile off. I brushed that one off as a "Well it's not perfect," now yesterday, I was trying to find a firestation in a city right outside of mine, and the navi took me about 4 blocks the wrong way after the final turn. I have noticed this before with trying to find houses, but with PUBLIC SERVICE LOCATIONS? WTH? I emailed Pioneer about the discrepancy, but they haven't gotten back to me yet. I just wanted to know if anybody else that has the newer Avics seem to be having this problem?
