Yes to both - disc won't eject and nav screen asking for disc to be inserted - I had the car in the dealers late november as my warranty was about to expire, so when I set out on the road trip my initial reaction was that the engineer had (inadvertantly) removed the disc.
So I'll need to take it in to the dealers for a replacement - I'll see if I can gather a few problems together to justify the 100 excess on the extended warranty. I'll report back with any amusing dealer anecdotes.
Thanks for everyones' help.
