So I bought a 2010 Infiniti G37x coupe with 55,000 miles on it from an auction this week knowing that it already had some things that needed to be fixed, which I am fine with that. One of the issues that I have with the car is that when I put the car in drive or reverse, nothing happens. another issue is that the navigation screen, radio, A/C, heated seats, or windows will not work. is there anyone that can give me some insight on these issues before I take it to the dealership?
