Maybe the CD laser is dead.
Try burning the OS to a DVD, the DVD is read using a different laser.
Check your OS CD quality using Nero CD Speed - a good disc is about 97 or 98% uality, with about <300 C1 errors, and 0 C2 errors. Surface scan should be perfect.
Yesterday my friend loaded a corrupt OS because his OS disc was full of errors (18,000 C1 errors, 300 C2 errors). Burning a new CD solved the problem for him.

+1
Happend to me, it was the cd quality !

Thanks for your answers, but I have a hope!

I was recoding an MK3 and I tought that it was a MK4!!!

If I choose settings of MK3 in navcoder and try recode language again, it would be solved?!!? Or I killed definitly MK3?!?!?

I can't solve it right now because I haven't car, but tell me something!

I need sleep!!!

If it's a Mk III then I bet you've used an ISO Mode 1 CD. The Mk III needs a Mode 2 CD to work. Your first task is to try and remove the disk thats in it, prey pressing the eject button for a long time, ideally as the ignition is turned on.

Your OS dis was probably Mode1, this will crash the nav.
Use ImgBurn to make sure you are burning a Mode2/Form1 OS disc. Then use the Mode2/Form1 disc and the nav should reload the OS OK.

Hi,

thank you vvvveeeerrrrry much! I will try do it tomorrow!!!

I will sleep better tonight!!!

In your opinion is better make first:

burn cd and insert it!

or

open navcoder, select mk3, make code language to force recode?

I'm trying make a portuguese version of navigation software! I'm almost there, but my girl voice is too artifitial. I'm making voice files from realspeak. Have you any ideia how can I make e real voice and more higer volume. The voice file .csf is almost finhished and I don't want make all again

I think that audicity make this, but I don't know how
Any idea?

Thanks in advance.

I'd like to take this opportunity to thank you and the whole forum. I just bought a 2002 X5 and, after reading here, decided to upgrade my MkIII nav which was at 3-1/40. After burning the disk & putting it in, I got a blank screen and continuous reboots, which I let run for half an hour. I did everything you're not supposed to do - I ejected the disk, I removed power, and I thought I had killed my nav unit, along with any display for the radio, OBC, etc. I was beside myself - but I checked back through the old posts.

Following the advice I found there, I checked the disk and it had been written in Mode 1 for some reason. I burned another making sure it was Mode 2/Form 1, and my nav came back to life, fully up to date 3-1/63 and working flawlessly.

Thank you!
