No need for the apology. They have been beating the oil drum for like thousands of pages. Just over what motor oil to use. I'm just glad you joined the LOC forum. This thread is still much better than the " What color air freshener do you guys think works best for my new car?" or the "Yo dog, those rims are mad sick bro!" It's all good.
And actually I think alot of people can identify with your issue. Maybe not the nav persay, but there are alot of choices to make when getting a new car, and you just want to make sure your getting what is best for you and not make some mistakes. Smart people generally ask questions, gather information, and then make the best decision for them based on that. We have literally hundreds of years of combined car buying/selling, and mechanical experience here. That's why this forum is such a great tool. I wouldn't be a bit surprised if somewhere down the road a year or so, you get a pm or a post asking if you were happy with your decision as they are faced with the same issue and just wanted to know if you would have done it differently.
