I downloaded V29.1 and burned it to a CD with IMGBurn 2X with verify. I unpzipped the files with WinZip. Upon installing the CD into the Nav system on my 2001 M5, the screen went blank. I am sure I did something wrong but can't figure it out.
When installing the CD into the Nav system, do you have the key on/off. What is the actual process one should go through to make that happen correctly.
Thanks for the help!

I first turned the key one pitch, inserted the cd, screen went black also, but after a few seconds the screen "installing" came on...
5 minutes later I had to press OK and everything worked.

I currently have the v20.1 OS installed on my Mark 4. I just bpught the 2007.2 maps. Does it mater whether or not I have an old OS? If not, can I upgrade maps then upgrade OS? Does one need to hapen before the other?

NAV in my 03 got intermittent. Took it to the dealer, who fixed it under warranty. They installed the 29.1 software. So far, so good; it works properly again except it seems to be in British rather than US mode.

That is, there is no accept screen anymore (yes, a minor blessing), but instead of counting down in miles/tenths/feet when you are near a turn, it's now in 3/4 mile, 1/2 mile, etc and counts down in yards. The dealer tried reloading the software, but still works the same. They told me they tried another car and told me it was the update, not British mode, but they would put in a ticket with BMW. Uhh, sure.....

But is that correct? I thought downgrading and upgrading gave you British mode. I really liked the greater resolution and would prefer it. Is there a way to get this back?

Not sure....the v20.1 I had dates back to Nov 2002 so at this point anything is better than that one. British Mode or not.

CAUTION-Since my navigation system has not worked since I upgraded to the V29.1, I took it to the BMW dealer and they have stated that the CD I installed caused an internal short in the monitor and the cost to fix it would be $2488. Any suggestions about option that I might have to resolve this problem?

^ how can software cause "an internal short in the monitor"?

Sounds like BS to me...

Good luck, I probably would have not told them you did anything to it. I asked the dealership to make sure my software was up to date when I took the car in for service after purchase. They didnt do it, but should I ever have a problem with the system, its doccumented that they checked and it was "up to date."

Bullshit from the dealer!

Please do a search on the forum or please someone confirm Piper the following:

Even with a blank screen, as long as there's some leds on, the navi is alive. Get a well burned cd somewhere else and put it in the navi. The system will reinstall the system even if you don't see anything on the screen.

The missing info is that I think I read somewhere that you might need to use an older version (e.g. 28 or 28.1), because if it's the same version the sytem will ignore the update. On the other hand, if you downgrade and if you live in USA, you might get the system reverted to european and you'll need to reconfigure the system using an ibus kit and some windows app available on the forum. But even in european mode, it's worth the try.

Hi everyone, First post on forum but have browsed site many times with success.
Have just upgraded from Ver.23 (4-1/30) to Ver27.1 (4-1/71) to be able to get "3D perspective" and it works fine. Am disappointed though that when in split screen mode the town/district name does not appear as it did beforein the right pane. Was especially handy when touring to know the name of the place.
Can this be resolved in any way? I read on this forum that Ver28 did not resolve it and I have not seen any mention about a Ver29 fix either.

Thanks
