nav dvd version?
 

hey guys! i've been lurking on this site for months. my parents bought a 2003 coupe when it came out and i just finally got mine about a month ago. anyways, anyone with a 2004 infiniti with nav, which version of the dvd did you get? i got 6.1 but was wondering if i should've been given 6.2. or is this version only available through the web? figure if i pay this much for the car, i should get the latest software. thanks in advance.
