Thanks for the encouraging words. I have a 2005 X3 with an MKIV Nav unit, so the MKIII isn't really a concern, but that is good information, thank you. I think i might work up enough gumption to try it out tonight.

There is slightly conflicting "steps" to executing the procedure. One account says to leave the drivers side door open (didn't know if that was car specific or not) when performing the upgrade and another doesn't mention it. I guess it can't really hurt to leave both the rear liftgate and drivers-side door open.

You don't have to leave the drivers door (or any other) open, just don't turn the ignition off during the update! Don't worry if the display goes blank for 15 seconds or so (just after it displays the message saying it's detected a software disk) either, that's normal.

Maybe it's me you were referring to as having recommended to leave driver's door and trunk lid open (you have thoroughly documented yourself, as that was some time back).

This is obviously not a must, non car specific. I was trying at that time to minutely describe a foolproof extra-safe procedure, in view of some people stubbornly experiencing a non so satisfactory outcome to it. I was trying to emphasize that extreme care should be taken in not disturbing the car's mind in any way while the operation went on. Thus, leaving the door open would not require you to open the door to click OK at the end, as leaving the trunk lid open would not require you to open it later, to extract the CD (maybe needing to retrieve the key to do so). I think I went as far a saying you should stand ten feet away from your car (thus avoiding the risk to cycle the contact key inadvertently).

The two important things to do: Be patient: do not cycle the key while the car is at it. Never ever use a Mode1 disk on a MK-3 system.

You don not need to be so timid about it. After all, even dealers can do it, and have it right on quite a few occasions.

Malaspina, uuhhmmm, I think I have heard this nick beforeRegards

Thanks guy for the additional encouragement...i guess my timid-ness is evident in my tone/post.

so how did it go?

"You are on the right track, except that the CD should be Mode2/Form1, then it can be used on Mk3 and Mk4

With a Mode1 CD you must NEVER use it on a Mk3 as it will crash the Mk3"


HOW CAN I GET v31 in MODE2 ? The software v31 I downloaded is mode1 for mk4 And for mk3 where is the file in mode2?


What kind of program should be use, to make chnage in POI ? I may change POI in all kind of maps? I got VDO Dayton v2008 Navteq, in what kind of folders I can cgange POI(add fotoradars, gas station etc.) Plz help

A) buy it from BMW
B) wait for someone to post a copy in the right format

Thanks
