Yeah, we have the tech package w/ Nav too.
the nav voice is annoying and the actual nav interface that nissan/infiniti uses is *** (compared to alpine's).

Alpine is more powerful, faster, easier to use = less eyes off road (yes you can program it on the fly).

My fav FX function is (drum roll) the laser cruise control. I call it DUI mode (hehe). the intelligent key is cool - but it can actually HELP you lose your keys (inside the car).

 

i suggest a winter beater but if you have to drive the g35c i suggest you get a set of winter tires the summer tires on the 6mt are terrible in the snow, but if you're going sedan i highly suggest the new G35x it has the awd atessa system

 

Try it, you will like it. I did!
