Mein Auto: BMW 740il 2001
01 740il Navigation screen

Hi,
I have a BMW 740il 2001 year model (e38).
I have recently changed my battery and after that the display screen (navigation screen) on the board went blank that is it has a (blue) light behind but no visual and the radio even cuts off in 2-3 mins and I have to turn off the radio and the restart it. When I saw the navigation system in the trunk the cd in it was coming out automatically in a few mins. The screen under the speedometer is working just fine and displays everything(that is the one in front of the steering wheel). I would like to understand what is wrong with it and what should I do to fix it. Even I am a student and so I would like to try all the cheap options first. I dont want to go to the dealer.

BMW 740il 2001 (e38)model Screen on the board

Even when I was jump starting the car I might have used the reverse terminals for jump start, is the fuse gone? where can I check the fuse and where can I get the cheapest parts?

There is a very good chance you accidentally fried your Nav unit. The Nav needs it's red LED light to go out (cycle down) before power is removed from it (via disconnecting the battery or pulling the power cable from the Nav). Not letting the red LED to go out first can cause the Nav to die.

The easiest way to determine that this is your problem (sure sounds like it is) is to borrow a Nav from a friend & see if his Nav works in your car & your Nav has the same problem you're having now in his car.

This is your car's way of telling you to upgrade to an MK4 navigation computer.
