Ok...so the only thing I have to worry about my new G-Wagon (02) is that the Navigation System is not working. It has a Navigation System in the car and everything but it is just not active and not working. My friend got this car a few months ago and said he never went to activate it or whatever and does not know why it doesn't work but it should work and there's nothing wrong with it. Can someone help explain why it won't work and what I have to do to get it working? This is really important for me! Thank you my fellow buddies!!
