Yes, you`r right. I missed to mention that my car is equipped with DSP and my ULF module works perfect. Did not try on car without DSP yet.

Will try this week and let you know.

I checked the mine PCB and found no differences between BM54 Back OG and BM54 NG. I`m not sure, is there any differences HW and SW in BM54 Back according production date
Any way, I`ll try to change the EEPROM and BIOS (atmel) chips as well and hope there will be no problem even in car without DSP...but let me first try

<grin> OK you know more than me on this.. but I'm becoming confused. What radio module do you think I have? (australian 2002/06 m3, came with 16/9 navigation screen and mk3 nav.)

One of the things confusing me, is that my radio does not fully mute when playing Nav instructions, which I believed was a function of the bm54?

I'd love to take a look at the radio module and confirm your suggestions, however it seems to be hidden away behind the HK premium sound system, is this correct? Is there an easy way to identify it without pulling everything out? The area is rather.. tight. (car was/is fully optioned)

Thanks

Correct. You have a BM54.

Radio service mode can confirm what model radio it is. Enter the service mode and look for the AREA setting.
If you see an AREA setting, it is a BM54

To enter service mode:
BM53 withWidescreenMonitor PRIOR to 9/01
1. Turn the radio on.
2. Within 8 seconds, press the 'INFO' button.
3. From the Info screen, select RDS (choose PTY on E38).
4. Press and hold the BM control knob (right side knob) for at least 8 seconds.
5. Scroll through functions using the station search buttons "< >".
6. Turn the radio off to leave the service mode.

BM53 withWidescreenMonitor AFTER 9/01
1. Turn the radio on.
2. Immediately press and hold the 'Select' button for at least 8 seconds. The screen will switch to Service Mode.
3. The screen will now show the serial number of the radio.
4. Use the "< >" buttons to select the desired service function.
5. Selections for the desired service function can be made by using the radio station preset buttons #1-6.
6. Turn the radio off to leave the service mode.

Thanks, I could not seem to get that info with a google search, must have been using bad search terms.

OK so next step is to check the radio and firmware.

(I'd love to get an Aux cable up the front of the car.. )

Again Thanks.

The update process is pretty simple if you're using onboard diagnostic/debug connector(red one on the PCB). Main mcu (infineon) has an integrated bootstrap loader to be used in such cases. In theory, I believe the update could also be made through IBUS as in DIS there's a service plan (Flash radio ) for some version of BM54.

I could help you but unfortunately the shipping cost to my location and back is pretty expensive.

Really?? I have the GT1 v44, DIS and Progman SSS v32, how easy would this be to do, would I need the newer bm54 flash image from a 2005 onwards??

Do you have any more details? (pm me)

Hmm, not to bad from me in the UK though

Sorry mate, now cleared

Mallee · #9 09-07-2010, 10:06 AM

I'd be quite interested to get any extra details as well

Thanks

Thanks Cream for your reply, I'm Italian but I live in US, maybe next time I come in Europe I can ship it to you (with Adrian Mutu's Fiorentina Shirt)....
I just bought the intravee II maybe is the best solution at least for me....I'll let you know as soon I receive it from UK if works.
Just another question, I just add the AUX 3.5 and a 3 RCA socket (audio to bm54 and video for the headrest LCD's) to my BM54, I have soldered a 300k capacitor between the two positive terminals, but my iphone works only via the 3.5 cables not via the original av/audio 50$ cable, AUX can detect it plugged just for a couple of seconds and than switch on radio, no problem with the 5$ chinese av/audio cable but after some seconds my iphone detect it as not compatible accessory.
maybe I'm using a not right voltage/amperage capacitor?
