I have a 2003 G coupe and it has the original Navi CD. Those of you that upgraded to the newest version (6.7 for 03's) does the voice change? I hope not, cuz i can truly say that this is the first navi voice that i like! idk if its generic but if its not, Nissan did a good job pickin that one out! so yeah, any input on this would be appreciated. I still need to find a new disk(or MDF/MDS) but if the voice is going to change then ill just stay outdated
