I've read many complaints about the Nav systems in our cars from posters. Just as well, I've heard from many who think that although it is not good as say Honda's or Toyota's, it does the job fairly well and is decent. Since I got the car, I considered myself in that second group who think it has flaws but is fine for the most part. My four years of use has brought me through these stages: (Like it----> Think it is decent---->Neutral feelings-----> Dislike----->Really Dislike------Hate!) My beef is not with the speed or lack of touchscreen or fancy stuff. Rather, the computer keeps screwing me over by bringing me to the wrong places. This happens about 40% of the time. I can guarantee it is calabrated and working properly too. For example, 79 Berry Hill Road, Syosset, NY. I enter the town Syosset, and then it doesn't allow me to enter Berry Hill road as if it doesn't exist. This is a major road! As I am typing it auto completes to something else. So, I then erase everything, and I attempt to put in the township: Town of Oyster Bay which includes Syosset. Then, I proceed to type in 79 Berry Hill Road and it comes up. Finally! So, I'm off on this trip and it brings me to that address in Oyster Bay which is in the Town of Oyster Bay just as well as Syosset. So, I thought Syosset was where it was bringing me. Thinking that Syosset was in this township, I thought that this was my destination and when I got there, it sure was not. I had to travel 4 more miles to get to my destination. There were two 79 Berry Hill Roads. One in Syosset and one in Oyster Bay. Mind you, this is the same road that runs through the towns. Please tell me...somebody, is this just a system quirk? This kind of crap keeps on happening to me. I think Long Island may be an unusually complex area because of all the townshps and towns within. It can get confusing. So, recently to solve this problem, when given an address, I go onto mapquest, enter it in and write down the cross streets. Therfore, I know for sure, that I am going to the right location because it is unlikely that there are two streets with the same names that interscet in another place. From now on, I dont' think I am entering a street in just by itself without a cross reference. But, how do you guys get around this when the computer auto completes your data entry to the wrong street and it doesn't show on the list when you know that your destination is in that town or township? Sorry for the ramble guys. Just totally frustrating when you need reliability. I can't seem to trust it. Please advise.
