There are no stupid questions!

Hi there fellow soldiers in the battle against BMW's faults and inadequacies.
I have been following various Eonon threads cos my radio BM54 is starting to go sideways but I have a question. When I replace the front screen/ monitor why is it necessary to leave the existing radio in place and plug back into it. Seems strange as it is not really working very well.

Good day!!

I'm not sure we (meaning ME) understand the question... Maybe I'll do some research to see if I can find what you are talking about...

One second... Be right back... Maybe....

Cheers!!

I could have been clearer I guess, the video I have seen shows that after running the extension cable back to the spare wheel well and plugging the 2 smaller leads into the extension cable the new cable is plugged back into the BM radio in the trunk is this correct?

If there is nothing wrong with the monitor in the dash, no reason to replace it. The radio sounds like what you need to replace.

True but radio repair is about $300 here and a whole new system is a couple of hundred more with more features . Plus my ulf is not working and Bluetooth would be nice.

That's not the radio in the trunk, it's the DSP amp. There's a pretty large thread on how to install these and similar units. Search for the Dynavin install thread (identical process) and the "stay away from Eonon" thread (don't believe the name, largely positive). Both are very detailed.

You must be new to this or something , the radio is in the spare wheel well , I have no dsp just the 6 stacker and TV module ,no nav . The monitor is just that, a monitor . The amp and radio are a single unit made by Becker mine is BM 54 . Dynavin are very hard to come by here in Oz and very expensive too. But back to the question .

Remember (or take note) that not all X5 radios/stereos are the same. My radio is in the dash (as part of the Professional CD player), I still have the CD changer in the back but with no DSP I have no audio modules at all in the battery tray.

There's a lot of variation, so OrangeFurious wasn't being totally daft.

The battery tray can contain a radio/amp combo (the BM54 module?) or just the DSP amp module. Sometimes the radio or amp module is in the left rear compartment under the CD changer too.

If I was adding a Dynavin or an Eonon to my car, there's nothing to run to the back. All the wiring is up front, including all spearker wiring. I'd look at relocating the MID display to the boor/trunk though, so I don't lose the MID functions.

If your car has Factory Nav and/or DSP then you will likely need a loom from the front to the back, to connect the the speakers at the very least. Each aftermarket unit will be spec'ed for a specific factory config. so make sure you get the right one for your exact car.

acidgreeny, since your exact car has neither NAV or DSP but still has the radio/amp module in the rear, you'll need a loom run from front to back for the speakers, some signaling and the aerial.

Wpoll thanks for the reply . I have the radio module in the boot but my question stands. After watching a youtube video it shows after plugging the two smaller plugs into the new harness it is plugged back into the BM 54 and am just wondering why?
