HI I have recently bought a 2002 Nissan Premeira SVE, however I am having problems with the sat nav. It comes on when it feels like it and when it is on is great. I have had it looked at by an auto electrican who advises that it is because the complete unit ie-radio,climate control are controlled via the sat nav dvd unit. He looked at it but cannot fix it as he does not have the specialist equip, I have look round the scrap yards however it seems that this is always the 1st thing to go. Is there anyone out there that can help me? Have you had the same problem? How did you get this fix, other than trade the car in I am not sure now what to do? Thanks
