Hey guys,

I have an Acura TL 1999 with hard drive disk Navigation ROM back in trunk and i have seen the Acura TL 2000 Navigation DVD Drive, and i really checked the cables ports, its same no difference there between 1999 and 2000 navigation drive cables, i mean they can be plugged.

my questions are
1-Is the TL 2000 Navigation Drive DVD will work in my car TL 1999 if i replace them because based on my searches i get confused about that.
2-the TL 1999 Navigation has a hard drive disk that only can handle one region as i read about, which means if want all US map, i should have 7 hard disks which is really crazy, so guys the DVD can handle more than one region or what?

thanks in advance guys
