Hi all:

Anyone know if there is a difference in the spec of 2001 and 2002 DVD Navi unit? I am asking because I recently made a copy of the 2.05 version navi disc, the disc played perfectly in my gf's 2001 CL-S, but when I put the disc in my car (2002 TL-S) my DVD unit have hard time recognizing it sometimes and when I try to find Acura dealer using the sort by distance function, it hangs the whole navi system. Only reason I can think of is that the 2002 DVD unit is actually a cheaper model and has weaker laser beams to pick up the data from a copied DVD. Anyone have similar experience?
