You paid to have the turbos replaced already? You should have called BMWNA and see if they would have helped you out with some or all of the cost of the turbos.
Put a regular DVD into the DVD drive and see if the DVD movie plays. It will only play while the car is in park.
You can always also buy the updated DVD navigation, but its like $300.00.
