If you own a MKIII and have these symptoms this fix (might ) correct it. ffice

ffice" />

Symptoms:

Blank Screen with white lines top and bottom.
Radio and CD changer works along with buttons to operate but music shuts off after 2-5 minutes. Can be powered on and same thing happens again music shuts off.
CD is stuck in NAV.

Reasons Why this happened:

You tried to upgrade to v26 with a hack splash screen or other non OEM files.
You tried to upgrade and the cd was corrupted and stopped mid way.
You replaced your battery and this happened.
You changed your radio fuse and this happened.

Tools that you will need:

You need to download v23 at this site. http://www.x5world.com/articles/all-bmw/navigation/9483-bmw-navigation-operating-system.html
You need to download this burning software ALCOHOL 120%, trial version here http://www.free-downloads.net/programs/Alcohol_120_
Download Winrar 3.51 so you can decompress files here http://www.rarlab.com/download.htm

FIX:

Unzip and extract all files to a destination you choose with WINRAR
Open Alcohol 120% and select burn from image, hit browse and select the folder you extracted to. Then select the file with the extension CCD and hit next. You will notice that 3 files populate with about 250mb. Hit next to continue.
Burn at 4x speed on a name brand disc, Memorex and better.
Explore cd to verify that it is readable, do this a few times and make sure it recognizes quickly by your pc and test open and folders or sub folders.
Go to your Beast and turn the key to the 2^nd dial, make sure your stereo is off, remove key and close door.
Open trunk, insert CD then CLOSE TRUNK.
Go into the car and turn key to 2^nd dial, Stereo should still be off.
Leaving key as is, exit car and close door.
You can wait but it is best to leave car behind for about 30-45mins and come back.
If this works your system will read update complete press okay to reboot.
I am free for lunch.

Your MKIII should have the newest version 3-1/63. This was a nighmare but just wanted to make sure members who encountered this has a step by step approach. Your NAV is not DEAD yet have faith and be patient.

Has anyone else tried this? I'm attempting it now, but while this instruction says to leave the key in position 2, other websites say to use position 1. Does it really matter?

My concern is of the battery dying after 30 min. of running the DRLs while the firmware is loading.

I tried this fix following the instructions to the T. I used a Sony CD-R. Tried to upload twice waiting 45-50 mins each time. Both times my nav screen stayed blank. Any suggestions on what I might try next?

Thanks!

I know it has been years but the links seem to be down and the software is out of date it seems.

Any walk throughs on this process with new links & steps?

Thank you
