Help Please E87 year 2012 - Best replacement option for the OEM Head unit
Hi All,
First at all, I'm from Paraguay (sorry if I make some mistakes while I'm writing in English kkkk) I have a bmw 1 series e87 hatchback 5 doors year 2012 and I would like to replace the OEM Head Unit. Can you recommend me the best option for my car? What do you think about this brands? Parrot Asteroid Smart DINAVIN N6 The audio installer said me that I have to replace the HU to improve the audio experience. (Currrently I have parasit issues too) Can you please Help me? Any help would be really appreciated. Here are some pics of my current OEM HU and the mods I already have done to my vehicle.

Silly question, why do you want to replace the head unit? If it's just because you're upgrading the sound? Changing the head unit is not going to upgrade the sound much, you should consider getting an amplifier for your door speakers in addition to your trunk subwoofers.
If you are having parasitic draw issues it's not because of the current head unit, it's because you're installer has done something wrong. |

Thanks for reply, The sound's installer said that he can not EQ with the OEM HU, that's why He needs to replace the OEM HU, besides the HU doesn't support RCA output and the remote. Can I just use the current amp of the trunk subwoofers or amp of the the trunk speakers to upgrade the sound of my door speakers? Best Regards, Juan Ricardo, |

The sound's installer said that he can not EQ with the OEM HU, that's why He needs to replace the OEM HU, besides the HU doesn't support RCA output and the remote. The EQ part is true, but you can get a harness that plugs in between the current connector in your car and the radio that will allow you to get RCA outputs. The remote output on your current head unit is pin 13 on the back, you can just splice into it. If you're current sub amps aren't wired with the remote coming from this location, this is why you have a parasitic drain. Quote:
Hope that helps. |

Do you have any pics about pin 13 on the HU's back, to show the guy who helps me with the sound mods? Where can I find out the proper hardness that will let me get the RCA outputs? About the Aftermarket HU, What brand of HU can I buy (fascia and connections included) to make a "plug & play" connection to avoid cutting the wires to make this modification? I really appreciate your help! Best Regards, Last edited by juanrikrdo; 10-19-2015 at 06:08 PM.. Reason: add more questions |

Have a look at this http://www.1addicts.com/forums/showt...arrot+asteriod
Its the parrot steroid with the Janus Facia plate. I don't have any pictures, but the wires on the back of the connector for the radio are numbers and you need the small and thin black wire in slot number 13. Tell your audio installer this and he should be able to figure it out. Sorry i'm not to sure where you can get the harness, but it's called an "Amplifier integration harness" and should be specific for your car. If you go this way you will also need your car coded to allow the head unit to output low-level unamplified signals that can be amplified properly by an external amplifier. |

I will search the "Amplifier integration wiring" specifically for my car (I hope to find it) By the way, What do you mean about the car coded? Do I need my car coded even with the OEM HU? Or just I will need this if I replace the OEM HU for a aftermarket HU? Do you have an external amplifier too on your 2010 e87? Best Regards, |

Your gongs won't work, your PDC won't work, if you have bluetooth in your car that won't work (but i assume the new head unit will have bluetooth) and unless you have the right integration harness, the steering wheel controls won't work either.
All the data for these systems flow along the "CAN" bus. If you remove the head unit (you can think of it as a receiver for the CAN bus), then naturally these systems won't work. For what it's worth, i really don't think you should replace the head unit. Many here have achieved fantastic sounding audio system still using the head unit. And if you get the right amp, it will have a HPF/LPF and gain control for each channel eliminating the need for an EQ on the head unit. |

Now the amps "sleep" about 10 seconds after the OEM was turned off and they turn on when the car "wakes up" (sorry for the expression). I'm still having parasitic draw. Searching for a RCA output adapter. I have found these products Ground Zero adapter http://www.caraudiodirect.co.uk/grou...evel-converter N-RHL2 adapter davidnavone.com/product/n-rhl2-2-channel-50-watt-per-channel-line-output-converter They say I would need one of these to convert the stereo output (high level) to a signal the amp can read(low level). What do you think? Best Regards, |

The ECUs in the car keep running for about 15 minutes after the car is turned off, so if you're checking the battery voltage in this time you are going to see a current draw. I think you would want the middle harness: http://technicpnp.com/product_purcha...eries_E82.html |

Maybe i'm confused, a parasitic draw refers to an electronic device drawing current from the battery when it shouldn't be and will call cause the battery to drain out, leaving insufficient power to start the car the next day.
What issues are you having? |

About the harness, what are you trying to do? I need to know exactly what your setup is. How many amps do you have? How are your current subwoofers wired? Where do the sound signals for the subwoofers come from? Do you still want to use the underseat subwoofers? Do you want an amp for all 4 speaker locations? |

How many amps do you have? I have 2 amps one amp is a Rockford Fosgate T600-4 to move 2 kits T1652-S MID, the other amp is a Rockford Fosgate T1500-1bd to move 2 subs Rockford Fosgate P3D4 10" How are your current subwoofers wired? Where do the sound signals for the subwoofers come from? The sound signals come from the driver's underseat subwoofer. Do you still want to use the underseat subwoofers? I'd like to use the underseat subwoofers if possible. Do you want an amp for all 4 speaker locations? I'd like to use one the amp I've already purchased if possible. |

Hello mates!
I'm still having trouble with the upgrade of my OEM head unit. I found this web page https://www.janus-design.net/english...-din/index.php but it doesn't work. Does anyone who has resolved this upgrade on a 1 series e87 with double din? I really appreciate your help! Best Regards, |
