    Hi,

    If I swap my BM54 do I need to get one from the same age car with the same set up?

    Mine's a 2005 E46 with full screen Nav and bluetooth/phone, no Harmon Kardon.

    Also can I upgrade firmware on the BM54 or the Nav?

    Thanks!

    You can use another bm54 from another car. Just be careful not to get one from an early 2001 model, which has the bm54 label, but has round pin connection.

    Both the firmware on the bm54 and nav can be upgraded.
