If the e46 has nav then the answer is yes, the radio modules can be swapped.

Great! Is the radio unit located in the trunk of the e46 as well??

I'm not as versed on the e46, but I would think so.

Today was my "big" day, I laid hands on a perfect BM54 tmc radio module..
I was ready for the swap and I removed all panels to access my current radio module.

To my surprise I noticed that I currently have a BM24 radio module, with a completely different connector! :mad: :mad:

So does this mean that no upgrade is possible whatsoever??? :dunno:

Off course I do not want to completely replace the cables, etc.

Or is it possible to make aux-in on the BM24 radio unit???

Many thanks

Does your radio module have the round pins or the flat pins? If it has the flat pins then it's a simple plug-n-play swap. If you have the round pins then it's doable but you'll need adaptor harnesses. I don't know if there's one to go from a new to an old, but there is one to go from and old to a new.

Thanks for your reply,

Is there anyone here who has tried this upgrade before? Would not like to come to the conclusion that I wasted a few 100 Euro's on a radio module, modified the oem wiring and find out that it does not work ... :tsk:

I upgraded my 2001 X5's radio module with the round pins to a 2003 radio module with the flat pins (using the conversion harness) and I now have AUX that works just fine now :thumbup:

Great,

Do you also have TV and DSP (coax from the cd changer) fully functional? :)

Many thanks.

I do have the TV functions, as well as Bluetooth fully functional. However, my car did not have DSP. But that shouldn't make any difference for you, since the radio module and connections are all the same, whether you have DSP or not.

My Dension IceLink plus is also fully functional, which took the place of my CD changer.

Great, thanks,

Did you build the adapter cable yourself or can I purchase it ready-made?

Many thanks
