DICE does like to handle the swaps themselves as they want to test the kits when they come back. Apologies for the issues to this point. It is possible but I doubt they simply returned the bad unit back to you. Let's get you fixed up though!

Is the new unit causing you the same issues as before? Have we tried a hard reset? The MB has the newest firmware?

My wife has a MB1500(which is one of the early test units) in her 04 X5 and it works perfectly so we can definitely get you setup!
