MkIII blank screen after dead battery change

PhinHead · #1 02-14-2009, 02:13 PM

I know this has been covered, and I have read countless threads on Nav losing OS because of changing the battery. I also know that since I have a MKIII nav, that any version beyond v23 is all identical as far as use in my MKIII. But I have been unsuccessful in getting the nav to boot off of any of my created CDs. I think it could be the initial cheap CDs I used, so I bought some Sony ones, maybe I'll buy some Memorex ones today. But 1 thing I noticed is that I have seen 3 different file types that get written to the CD, depending on where I down loaded the os software from. 1st download (v27) has as its main file "bmw v27.mdf", 2nd download (v23) was a cloned CD image and its main file is "BMW_v23_update_darci.ccd", and the 3rd download (v31) has its main file as "v31_OEM.bin". I have always used winrar to extract the files and alcohol120 to burn them on to various CDs.

I have followed the steps of putting key in position #1, I wait 5 minutes (since my screen is blank I can't see when the nav has booted) and then I insert the burned CD into the nav unit in trunk. I never have seen anything come up on my screen other than some white junk flashes that come up regardless if I have a CD inserted in the unit, only LED that comes on on the nav unit is the eject LED, never the "power" LED.

I am desperately trying to NOT buy a new nav unit, also my radio only stays on for 2min40sec then cuts out, which I was told MIGHT be that the bmw iBus senses a problem with a device on the bus and therefore shuts the bus traffic down, hence the radio cuts out.

I bet all this sounds familiar. My last download, was extracted but when I went to burn it using alcohol120, it wouldn't burn, so I will try to download another version and burn it to a new CD. Any pointers, like where is the BEST download version to get the OS from. Second, how do I know the difference between Mode 2 and Mode 1 and what is the harm if by chance one of the OS CDs I burned and tried was a Mode 1 and I am in US.

Thats enough questions for now.

Try this ONE and use ImgBurn to burn (You have to see mode2/form1 when burning)

Software was forced to SW 3-1/64 (don't need downgrade)

You're burning wrong

The BIN, IMG and ISO files etc are not files that you burn to the CD.

These files are Cd images.
You need to create a CD from the image using an image writer, such as www.imgburn.com

Do NOT just copy the files directly to the CD. That won't work.

Ok I used the linky for the nav os provided by Angelynch above and the imgburn sw suggested by KiwiJochen as well. I like the interface for the imgburn better than the alcohol120.

I believe a properly created a nav os CD using the winrar to extract and imgburn to burn the CD (I used the 2X speed in this case).

I put my key in position 1, walked away for about 5 minutes (display monitor is OFF, as I had it turned off before I took the key out the last time I had the vehicle on), so in addition to the blank screen in general, I also have the display off. After waiting 5 minutes, I assumed the nav is booted up to whatever state a nav system can that has a wiped OS, and then I put the newly created BMW NAV OS CD into the MkIII ( I did NOT have a map CD in throughout any of these initial 5 minutes), and I walked away. I can hear the nav unit trying to read, but it sounds like it is in bursts of 3 or 4 attempts, then the unit goes quiet for a minute or so, then I hear 3 or 4 "reading bursts" again come from the nav unit, and this continues on for as long as I decide to just stand there and observe. Nothing ever comes up on the display (but again display is off) and hours later (started this over night) I eject the CD (never ejected on its own) and still nothing on the display and radio still cuts out around 2 minutes 40 seconds after ignition is turned back on next time. So I am not sure if the "reading bursts" are normal or if the CD is still not correct or if I am doing something slightly wrong in the procedure.

Also before I did anything, I ejected the nav unit from the housing and unpluged the antenna and the 2 connectors on the back of unit. I did this with the battery completely connected, not sure if ejected the unit or disconnecting it with power still applied matters, but I believe i read somewhere, where it was suggested to disconnect the nav unit for a couple of minutes (although I did it for an entire weedend as I was out of town), before you start the uploading of new OS process.

Any suggestions... my apologies for the long email, but I want to give all the details as maybe one of them matter. Thanks for all the help / suggestions so far.

Disconnection fro a couple of minutes could not help...... Try to disconnect for 15-20 minutes

But this is not good that navi returnes disk
