Thanks for the info!iDrive 7 has no MOST, RAM (factory amp) is connected via OABR.
iDrive 6 uses "NBT-EVO" head unit, not newer "MGU" head unit.Thanks for the info!
So, I did some quick digging around and it seems like iDrive 7 Professional uses "MGU" in replacement of "NBT-EVO". It does not have a MOST connector at all and instead uses OABR. It also does not have a traditional "quad lock" connector, which is used in I think pretty much all older cars from all manufacturers. More info from the wiring: http://www.bimmercrew.com/2018/10/news-bmw-head-unit-mgu.html
Does iDrive 6 use the "NBT-EVO" head unit or the newer "MGU" head unit?
I think iDrive 7 Professional is only included in G30 5-series manufactured 07/2019 and fowards, while 06/2019 and earlier still use "NBT-EVO". Can anybody confirm this information?
65122622873 and (and equivalent supersessed part numbers) are for the iDrive 6 (NBT-EVO) harman/kardon amplifier, with MOST connector.
65129832609 and (and equivalent supersessed part numbers) are for the iDrive 7 (MGU) harman/kardon amplifier, with OABR connector.
However, I haven't been able to find a picture of this amplifier with the OABR connector. Does anybody know where I can find one? (My car hasn't yet been delivered, but when I get it I will attach a picture here to help other people out.)
Also, does anybody know of a DSP that can connect to the OABR interface?
Either 1) process the signal and apply equalizer and speaker timings
2) convert it to a TOSLINK digital/optical output so it can be equalized and converted into analog in another DSP
3) covert it to analog using a higher quality than the one in the head unit or factory harman/kardon amplifier
I'm also trying to find a way to install a proper DSP on a G15 2020 with HK option 688... Did you end up finding a solution?So, my question remains: is there any way I can get a digital audio signal from the system? like using an aftermarket processor to intercept the OABR signal before it reaches the RAM?
You probably wonder why would I want that.
Firstly, because I'd still be able to control the volume using the iDrive instead of having an external volume control.
Secondly, because the DACs (digital to audio converter) and also the amplifiers on the RAM and Booster are crap.
On the MOST25 vehicled (BMWs until ID6) and MOST150 vehicles (new Mercedes and VW Group) I can connect a DSP (such as mObridge and NAV-TV ZEN-V / ZEN-M) replacing the OEM amplifier. It's perfect.
It looks like the only way to install an aftermarket audio system would be to take the degrated signal from the speaker out wires from the RAM/Booster, right? I really dislike that idea though
I didn't spend much more time researching.I'm also trying to find a way to install a proper DSP on a G15 2020 with HK option 688... Did you end up finding a solution?
