I have a 2007 Chevy Tahoe with factory navigation installed. When I had my truck serviced by my mechanic, he told me that the voltage on my battery was low and that I should have the dealer take a look at it. So I took it in and they said that the battery is fine but the navigation is constantly spinning the disk and draining the battery. So they replaced the navigation unit and I picked it up tonight.
My questions is: Is there any difference between the 2007 navigation units and the 2009? It looks the same from the outside, but I swear the blue screen is darker blue and the clock in the right hand corner is bigger. If so are there any other differences? Or am I making all this up in my head?
