Hi there, having just bought a 350Z, after saving forever, I now understand all the raves about this superb car. Mine is a 54 plate, with 31000 correct miles, and I love it.It has a built in Sat nav system, but the guy I bought it from had lost the CD-rom that powers it. I ain't the most technical guy, but I've made some enquiries, and it seems that there are two systems, The CD X6, and the DVD X7. Trust me to have the CD system. As I'm new to the car, and can't tell you how re-assuring it is to know there's a wealth of interest and expertise out there, I'd be truly grateful to hear from any member who may have an old CD rom for my X6 system. I don't really care if it's a 2003 version.I will ofcourse pay for it, but just want to see what it looks like at the moment !. I'm in for the long haul, so I'll be asking you experts for advice later on about an upgrade system, or replacement system like the Nurrish I've heard about, but don't know how to make contact. Sorry i haven't got anything to contribute at the moment, but hope as time goes by I may be able toput something back in the pot ! Thanks all Robin5000.
