Yeah, the roof is the same as the E89 only has an extra panel. It has a party trick too; the whole boot section lifts internally via a switch on the inside of the bootlid, so when the roof is stowed you can get access to stuff in the boot. It is massively over-complicated and another excuse to go wrong IMHO, so try not to use it.
