2001 740il: navigation..nav...the radio also cuts..few minutes

Resolved Question:

My 2001 740il navigation screen is blank. It is a late model 2001 with the wide screen nav. I know this is a related problem, but the radio also cuts out every few minutes... so I need to hit the power button twice, once to turn it off, and once to turn it back on. I do see the nav screen flicker when it is dark out, and can see that it's definately 'on' despite being just black and having no image. Previous posts refer to the problem being only the nav module. Is this true? If so, please clarify if this is the navigation unit that accepts the disk, or if there is an actual module/box somewhere else in the trunk? I know it has to be matched to my 01 with the wide nav... but will a 01 5-series with the wide nav for example be a compatible donor car? Even better, if you have a part number for the unit available, that would be GREATLY appreciated. Thanks

Hello and welcome. These are hallmark symptoms of a failed navigation computer, the unit in the trunk. The part number will be printed on the unit so you can match this with a replacement. A replacement will need to be programmed to the car at a dealer.

 

I hope that is helpful, please let me know if you have further questions, or if I can clarify anything for you.

 

It has been my pleasure to help today and I wish you the best of luck with the vehicle.

The navigation unit meaning the actual unit where the nav disk is inserted, not another module, correct? Thanks

if you have rear screen display it will be different, but I assume you do not.
