Ok so I bought the d1 from craigslist and I hooked it up today to find this...when I insert the west coast map disk everything is fine until I try to input a destination. I get through the part where you type in the house number but it freezes when I enter the street name, then after a couple of seconds it goes back to the map screen. I also did notice that the disks that I am using are not the original pioneer disks. On the disks it says, CNDV-60m WEST AND THE SAME GOES FOR THE EAST. It does not say on the disk weather or not if it's a dvd-r dl or a dvd+r dl. I also do not have the reverse wire of the vss hooked because the best buy install guy said they were not needed. is there anyone that can help me or am I doomed lol?

so nobody huh? 1 more thing...I inserted the nav dvd-rom into my comp and it's only 3.2G for the whole thing...is this the normal size for the nav disk?

Nope.

ok so now I am taking the disks back to the guy I got the unit from and he's going to give me 100 bucks back. What I want to do is make copies of them so I have them for myself. How would I do this? Do I just put the disk in the comp and use nero to "make exact copy of dvd"?

If you don't know how you shouldn't try. it is a very tough procedure. (Ripping someone off and all)
