Navigation Disk Keeps Ejecting?

Has anyone else ever experienced any issues with there NAV Disk not staying inside? Mine constantly ejects for no reason at all.

You didn't mention which Nav unit you have in your 7 (or what year your 7 is).

But, is your map disc an original one or a copy? Some people have had issues with copied maps not working correctly.

SB, thanks for the reply. I have the MK3 currently in my 2001 740i. My disk is original OEM and I experiencing a few pixels missing on the screen. Do you think I should just upgrade to the MK4 and call it a day?

Personally, I'd try to borrow a known working map disc from someone else (or, have your OEM map disc put into a working MKIII from someone else) & see what happens.

Then, I'd swap (with a friend) that also has a working MKIII & see if his/her MKIII works fine in your car & your MKIII has the same problem in his car.

Those would be much cheaper test methods than just going out & buying a MKIV. But, my GUESS is a MKIV would solve your problem. I'd just want to be really sure your MKIII needs to be replaced before I'd spend the money for a MKIV (unless you want to upgrade to the MKIV anyways).

Let us know what you find out.

Check the disk in sunlight for big scratches or swap discs with a pal?

I also have just had this issue, and have no clue why it started rejecting the disk. I tried two different disks, each of which used to work fine.
I first noticed VERY slow response from the nav system while trying to input a destination, then it completely stoped working.

How can I tell which nav unit I have? There doesn't seem to be any identifying labels that I can find..

Thanks for any help..

Assuming the Nav hasn't been changed out in your 2001 7, then if you have the smaller screen (4X3), then you have a MKII. If you have the widescreen (16x9) up front, then you have a MKIII in the trunk. If the Nav in the trunk has "DVD" on the unit, then it's a MKIV.

Try a head cleaning disc or blast of compressed air (carefully).
