New to the forum and to MB (just picked up my E63 on Sat) and must say I've been missing a lot (previous M owner)

I have 2 questions:

1. I am unable to copy music on the 4G command consul via the media interface - the option to copy music files does not highlight - any suggestions would be appreciated..

2. the 1000 mile break-in period - how real is this?

Thanks
