I have a October 2004 X5 (facelift) with NAV but no DSP. It has the MK4 DVD unit in rear.
Are the radio modules age related at all to give me a clue as to which I have?
Thx

afaik, bm53 is for usa market, bm54 for european market, if is the original radio module (that means mfg date is 2004) - most likely is bm54 with aux input, no mp3tag or audiotext
