I'm using OEM middle speaker, I was able to connect to pin 13 but the speaker goes up when I unlock the car, and it goes down after 60 second after locking the car, I have the HK on F01 2015 but F10 and F01 use same system as far as I know. is there a way to make it work when the radio turns and shuts down when the radio is off? Thank you so much! |

I know this thread is old, but did you ever figure it out with the radio power? I would think there would be away to tap into the iDrive screen turning on or the climate control since they are only live when the car is on.

And if this pin is not populated, you can get a socket crimp it on to a 20 gauge wire and run it up to your B&O center speaker. If unpopulated, you will need to use BimmerCode or ESYS to code the "RAD_ON" to function. It might already be active and populated if you have active sound. You can use any power source that runs off the Terminal 30B power rail, such as Fuse F119 in the Glovebox Fusebox, or the cigarette light, which too runs off the Terminal 30B power rail. |

Pin 1: GND on chassis ground comb location Z10.13B (Brown Wire) Can use any ground, probably use the lighter ground Pin 2: LED (+) from B&O Amp Pin 2 (Purple/Yellow) I can connect to any positive LED probably going to use the lighter LED Pin 3: Motor (+) from B&O Amp Pin 16 (Yellow/Red) This is the Rad ON PIN 13 correct? Pin 4: +12VDC from JBE Connector Z7.2B Pin 4 (Red/Brown) I can use terminal 30 off the fuse panel or connect to the power at the lighter as well for this one

Note 1: A motor requires an initial surge Current, then tapers off. Not sure that the RAD_ON discrete signal from the head unit can source the motor surge Current from the internal FET. An LED? Yes, it's a low enough current value which the internal FET should handle since in some vehicle this signal has a fan-out drive capability of up to three other loads, one being the Active Sound ECU. So how should you do it? Well, it depends on when you want the motor to come on. My suggestion is to use a micro DC relay ($9), 5th picture down provides the schematic/hookup diagram, and your speaker motor will be where it's labeled "device". There is enough room for this size of relay within the dash area, where the larger ones might be too big. Use the RAD_ON line to drive the lower current side of the relay, and your electrical socket to power the high current side of the relay. This will then work like the factory, where the motor lifts up when the radio is on, and lower when the radio is off. Cheers. Last edited by M_Bimmer; 04-17-2024 at 08:17 PM.. |
