I don’t normally publish this sort of thing but this one’s a little strange and fascinating.

In via email from Michael, a problem with the entertainment system in a 2006 9-5, which he refers to as the ‘Premium 200′:

If I play an MP3 CD-R and turn off the ignition without removing the key the radio system forgets where it was on the CD-R. It also forgets about all changes to the treble, bass etc that had been made since the radio was turned on.

If I also remove the ignition key everything is fine and the radio remembers that I was playing music in folder 27 on the CD-R.

Anyone else got this problem?

Saab, are you aware of this problem?

Any solutions or suggestions welcome in comments.
