well, considering a new d3 retails at $999 and the D1 used to retail at $1899, I figured in the $600’s would be a fair price. but I guess I’m open to offers.
on a side note, not trying to make mine sound better or anything, but the D3 sucks ass for nav. you have to load the disk in every time you want to set a destination. the D1 has a designated slot for the nav disk, which never has to be taken out.
