Before you plunge into a aftermarket Head Unit
Before you plunge into a aftermarket Head Unit
There is some stuff you should know about putting a aftermarket head unit in a E9x. There are some side effects and things to consider. The BMW Radio or I drive is integrated into the car in such a way that if you remove it you will not be able to get software updates or repairs at BMW dealer without remounting the original BMW Head Unit. To get around this some do a parallel mount of the original Head Unit in the trunk. Additionally depending on what options you have they may cause error messages or cease to work and cause error messages. SOS will cause a error message if the original radio is removed. I also have read you will loose at least the audio indicators if you have PDC and in some models the chimes come through the stereo speakers via the radio. Also if you happen to have the Logic 7 sound system there is only one aftermarket Head Unit that will interface with the Logic 7 amp and that is the Dynavin N6 with a logic 7 adapter built for the N6. (because of the proprietary fiber optic interface between the amp and head unit) head unit http://www.e90post.com/forums/showth...ight=head+unit http://www.e90post.com/forums/showthread.php?t=1036190 http://www.e90post.com/forums/showth...hlight=dynavin http://www.janus-design.net/english/ http://www.e90post.com/forums/showthread.php?t=355089 http://www.e90post.com/forums/showth...ight=head+unit http://www.e90post.com/forums/showth...hlight=dynavin http://www.e90post.com/forums/showth...hlight=dynavin http://www.e90post.com/forums/showth...light=retrofit http://www.e90post.com/forums/showthread.php?t=993447 http://www.e90post.com/forums/showthread.php?t=1016187 http://www.e90post.com/forums/showth...hlight=dynavin BMW stereo types http://www.e90post.com/forums/showthread.php?t=352586 http://www.e90post.com/forums/attach...2&d=1266451970 http://www.e90post.com/forums/attach...2&d=1260829447 http://www.e90post.com/forums/showthread.php?t=343673 http://www.e90post.com/forums/showthread.php?t=138949 http://www.e90post.com/forums/attach...1&d=1209780605 http://www.e90post.com/forums/showthread.php?t=641323 http://bmwcoders.com/forum/3-er-8/bm...1-e92-e93-291/ http://www.e90post.com/forums/attach...1&d=1209780865 http://www.google.com/url?sa=t&rct=j...,d.cGU&cad=rja http://www.musicarnw.com/page-2/ http://www.e90post.com/forums/attach...4&d=1278871872 Last edited by ctuna; 01-18-2015 at 10:27 AM.. |

I already have a jvc headunit I was planning to put in, if the car does not have logic 7, and idrive, is it difficult then? Wouldn't I just need the double din, wire harness, and steering wheel control adapter?

You can have side effects .
You can have side effects .
Did you read the part about repairs and software updates. You need to do a parallel mount of the old system or be ready to put your old head unit back in if you need to go back to the dealer for anything. The connects 2 Harness is what a lot of people are using for this now. Also you need to know which of the three BMW systems you have to do a good job and wire it correctly. You need to identify your BMW system what year car do you have? If its US 09 or earlier it will be Hi Fi or Logic 7 system if its 2010 or early 2011 you may have stereo or base system . There will still be issues with things like SOS and PDC if you have it no matter what system you have. The basic thing is to do it correctly its more than just throwing a harness on a Head Unit in and some steering wheel controls. The member BMW325i has done this and knows how it goes. Best to list the year of your car and what options it has to get accurate help.(which system and which options) Don't throw your old BMW head unit away of sell it you may need it to get work done on the car.

All cars before 09 in the US have either Hi Fi or L7
All cars before 09 in the US have either Hi Fi or L7
PDC is parking distance control BMW SOS is about the same as GM ONstar. Its essentially a built in cell phone and GPS. Both of these work through the stock radio. Hi Fi has a amp in the trunk its 6 channel . Read the description of Hi Fi in the links above. There is also a description of how to deal with the issues in the above links. |

I think the connects2 is made for BMW
I think the connects2 harness is made for BMW
also I was under the impression it allows parallel mount of the radio. Also I think it has the whell controls built in. Not sure BMW325i has one. |

Extend power, and 2 can wires. Ground to the chassis. If you have most you can use extra cables in the trunk if you have any or connect new ones to the distribution block and use a most termination loop in the dash. |

http://www.dynamicsounds.co.uk/bmw-1...n-support.html If you are relocating the headunit you also need this harness. If the headunit doesn't have a MOST bus then it is pointless to relocate it. http://www.sonicelectronix.com/item_...a-71-9003.html Are you using the hifi amp or are you replacing the amp and speakers at the same time? What model JVC headunit are you installing? Last edited by bmw325i; 01-20-2015 at 05:57 PM.. |

I'm not sure if this will work for your headunit, but it will plug into the connects2 harness. I couldn't find an ISO harness for mine so I cut the ISO connectors off, and soldered in the harness that came with my headunit. Then I covered it all in heat shrink. This isn't really needed, but it might work. http://m.ebay.com/itm/260741319554?nav=SEARCH If you are using the stock hifi amp you need to use the rca inputs. Like how it's done here. The diagram is not exactly the same since he is using the metra harness and a steering wheel adapter, but the pinouts for the rca wires is still the same. http://www.e90post.com/forums/showthread.php?t=809490 |
