I just bought an 04 Landcruiser with nav and have several questions. I feel like I got an incredible deal at $37100. The Nav DVD was stolen (can I get an inexpensive one other than the dealer?) so many of the screen functions do not work. Would this affect the rear camera?(pic doesn't show up) It has 60,000 miles but looks and drive perfect. I noticed it does have the "clunk" Is this common in the new ones as well? Remedy? Will that hurt anything If I don't address it immediately? By the way there are several functions I wasn't aware that it had like the computer that calcs MPG and miles to empty.... nice! Also bluetooth on the 04's! I thought that was only on 05's! I am alittle worried about the Nav. Does not having the CD limit many funtions?
