What did you have to change Paul?

Nothing. I stupidly left some CD's in the changer so the whole lot had to come out to power up the changer and once I'd put it all back in again, it's fine. Luckily (and unusually for me) I took a look at the instructions FIRST before ploding on and noted that it works from CD5. I've now discovered a track list and other features which is excellent. One question you might be able to answer is why does the main display show the music time running from 0.00 and the maxidot showing from say -5.43 to 0.00 ? Shouldn't they be the same ?

I don't think the headunit can display time remaining so I guess they decided to implement time remaining on the cluster rather than just copying what it says on the headunit
