Upgraded Mk4 nav with v31 disc, showing v4-1/40...help - Page 2

I have checked the files in the OS v31 and they dedinitely show 10.00 (1000 in the disc).

I managed to download a copy of v21.1 and loaded it into the nav. It went down to 4-1/12, the I tried to load v31 again. I thought everything was okay until the very end it said there was an error.

Now I can't load any OS onto it. The dvd drive has the lights flashing on and off intermittently, and the disc whirrs away like it's reading discs but nothing else.

I tried to reset it by unplugging it, but that didn't work. So I plugged in the Navcoder onto the iBus to see what it was doing. It recognises the nav but theirs no part numbers listed, and on the device logs it shows NAVE - RAD Device ready for reset (or something close).

Have I knackered it??

Make another new, clean V31 disc and try again. Beofre you use the disc, check and test the disc to make sure it is good.

You probably have a weak laser that resulted in some errors during the burn process. You just have to try again, possibly with different media. The best thing would be to use a new pressed disc (purchase from BMW).

I've tried with several new cds burned in mode 1 and mode 2 for virtually all known OS for the DVD, but it is still refusing to update.

I don'y know much about these units, and have looked on the forums but can't find anything similar - when the unit is plugged into the power and iBus, it goes through some of cycle...

red light flashes on and off, will occasionally stay fixed on (constant whrring at this point) then it sounds like the laser hed is moving twice, finally the red led goes out with the orange backlight on the eject button and there's no sound as if the power has been cut. It then does this all over again. It takes about 30 seconds per cycle of doing this regardless of whether there's a disc in or not.

I've spent so much time on trying to fix it, and not getting far. It's so frustrating

Sounds like laser is on its last legs or now dead. Try a new mechanism from the dutch people:
