Greetings Team,

I purchased my X5 4.6is 2003 model three months ago, i have downloaded the Software from here for the navigation the v32 and i did the upgrade successfully .. one month after i wanted to change the splash screen, so i follow the instructions and created the new image, i started doing the same process for the upgrade, the screen changed to black after the message software updating and never come back!

I turned of the car and turn it on again and the screen went back to the Standard Blue Software WITHOUT NAVI APPEAR!

I checked again the Navi MK4 computer for the update, i found that the power small led under the eject button is no more lighting!

The DVD keeps turning inside the MK4 without reading anything .. and the Power Small led doesnt come up!

Does this mean that i lost the MK4 computer? is there anyway to fix it? Pleae Help ..

Recover your MK4 with version v27.1 or lower...

Before downgrading make the resen of the navi unit

1. Swith the ignition off, close all doors, open trunk
2. Wait till LED on the navi goes off
3. Dosconnect two jacks on the back of your navi
4. Wait 15-20 min
5. Connect jack again
6. Follow the procedure for navi SW downgrade/upgrade....

Good luck

Thanks dears,

I will try this today exactly as you list it and will let you know, but i have one point only, open trunk ... What do you mean by Trunk? then you mentioned wait untill Vavi led goes off, you mean the eject button light? because the power led already doesnt work any more ..

Appreciate all your help

Trunk = American for Boot
If your car is not a saloon car, then you may not have a trunk / boot :-)

Thanks WiKi .. I got the trunk means :) ..

So, i have tried the procedure above .. and again the same issue ..

The main thing is that the POWER led doesnt work at all .. Nither on turning on the car or inserting a CD or anything ..

Only the eject button working and the DVD keep turning inside without updating or reading the DVD or POWER led lighting :(

What does this means? i have tried v27, v26, v17 .. Even i got an original OS from the BMW dealer ..

Any help team???

Thanks ..
