Interesting. This is non-DSP only, correct?
The DIY applies to both DSP and Non-DSP vehicles. Mine is DSP with M-Audio. The CDC Connection Cable (P/N: 65128364756) is required as the BM53/4 radio does not have the coaxial input that the C43 (DSP) has. For Non-DSP vehicles the purchase of the CDC Connection Cable should not be required. :cheers:

Just to confirm the Mk. III will only display the channel in the OBC display in the gauge cluster, right?
That is correct. When you press the "Mode" button it will scroll through the usual menu (FM, AM, CD & Tape). However, it will appear to stumble after "Tape". This is the Sirius Mode. If you can still find a cassette, put it in the deck as this will help discern the different modes or watch the OBC as you are scrolling slowly through the various modes.

Thanks for posting this. I have done the upgrade before on a previous M5 and now I tried it again and it was not successful. I think I am missing a cable:

I already have:

1 - BMW ADAPTER CABLE, RADIO P/N:
61126913957
1 - BMW ANTENNA ADAPTER TUNING P/N:
61126913955
1 - BMW
ADAPTER CABLE, CD CHANGERP/N: 61126913954

I see two parts that you listed that I do not have.

1 – BMW CDC ADAPTER P/N: 61126924785
1 – BMW CONNECTION CABLE CD-CHANGER (550mm) P/N: 65128364756


One other potential issue is that the radio came from a 2003 3-series. I did remember the first time I did it I had to mess with the cable going to the CD changer and this time I didn't with the parts I ordered. Thanks for giving me some direction to troubleshoot it.

I'm considering adding this, but I've already got a BM53 unit installed as a warranty replacement for the original C43. Because of this I'm not certain I need the full list of parts. I think if you already have the BM53 then you don't need the following (purely speculation) -

BMW CONNECTION CABLE CD-CHANGER (550mm) P/N: 65128364756
BMW RADIO HARNESS P/N: 61126913957
BMW CDC ADAPTER P/N: 61126924785
BMW ANT ADAPTER P/N: 61126913955

My guess is that they should already be installed as part of the BM53 installation. Can anyone confirm this so I don't need to go dig through the wire harness?


Edit...
Should have done some more searching. The above seems to be corroborated by AGM5's post here - Link

josiahg52,
I am sorry for not responding earlier, work has been hectic and a lot of things have been missed. Did you get your Sirius up and running?

Bat711,
If the BM53 has already been fit, than yes, you will not require the radio harness adapters you mentioned. You will still require the CDC slave cable (P/N: 84110150526) if you wish to retain CDC (or other e.g. Intravee II) functionality.

That's a hell of an expensive tab for the addition of Sirius.

If you're cheap like me, the solution was ~$150 for a GROM Audio bluetooth unit and my cell phone (and I guess the DICE DSP adapter as well).

OP: love the BPM station choice!
The problem with the Smart Phone / AUX or Bluetooth is when you're travelling cross-country and you lose cell and or data service. On my last trip out West I was constantly losing cell service and or data service. When cell service cuts in and out every 45 seconds or so for 300 miles it gets a bit annoying.
Yes it can be expensive, if you doing a full upgrade as I did. If however, you already have a newer BM53 it's pretty cheap, especially if you factor out the $140.00 for the first years’ service.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com<img src=" /><o:p></o:p>

Yeah if your unit was upgraded to the BM53 due to warranty claims you could essentially add Sirius for a net cost of about $200. Mine had the stereo switching to mono issue.

Plus I got to use this as an excuse to my wife to swap a MK IV nav unit in at the same time.

TS question.

I'm in the process of doing this upgrade, in steps, on a 2000.
Installed MKIV a while back and it works great.
Ordered the first 5 items on the first post and installed them this morning. Well, except for the antenna adapter; I forgot to order that.
Went to test and no joy. Nav works but Mode, AM/FM or presets do nothing. I double checked all of the connections with the same results.
My guess now is a bad radio. I ordered it from the dealership so it's not used. It is part number 65126988276

Does anyone have any suggestions?

TIA

ps, great write up AGM5, thank you.
