Why can't I upgrade my MKIII?

[Thomas Olivaux]

Hello!

Since two days, I have my E46... and I try to update my MKIII nav without success Why? I downloaded v22 and v26 images, I burnt them to hih quality CDR (Verbatim), 1st at high speed, then to the lowest possible for me, 4x. Each time I try, I put the ignition in position I, when the screen is on, I eject the map CD and I insert my v26 CD. A few seconds later, the CD is automaticly ejected, the screen saying that it's not a correct CD What's happening? When I'm reading thoses CDRs on my PC, I can see the content without problem...

Thanks you for any input,
