E61 logic 7 retrofit

[///MPROVD 131]

Hey team i got half way through this retrofit before i thought of posting so bear with me lol. 

the story:

Ive done this retrofit before with my old e92 and when i did i fitted the amp before the speakers and the amp alone made a huge difference to audio quality and the 535d was in dire need of better audio. 

Unlike the hifi option in the e92 the e61 hifi system doesnt have a amp so the only difference between standard and "hifi" is the addition of subs and a small sub only amp. 

L7 amp VS hifi sub amp:

L7 option ($677) consist of a DSP amp, front 2x door speakers , center dash, rear 2x door speakers, 2x boot roof speakers and finally 2x subs under seats

Id already swapped 4x L7 speakers i had in front doors and rear roof. Ive yet to pull the rest of the subs, speakers and tweeters from the donor car. I used the non L7 speaker for the center so ill swap all the rest at a later date

what i did:

front left and right: Because having amp in the e92 meant that all the speaker wires ran back to the boot this was not the case with the e61 but lucky for me the sub amp meant there was a power supply and the sub wiring already run. On top of that 2 line level input pairs looped off the quadlock connector for the iDrive supplied audio to the amp. 

This provided the front left and right channels. I cut the speaker outputs from the quadlock and joined the front speakers to the 2 pairs that ran to the old sub amp. Then joined to the L7 amp.

 

 

Center: After that i still needed to add the center dash channel so i needed another pair to the front. The amp is mounted on the rear left of the boot and the rear left speaker ran right past the amp so i cut the pair and the speaker end joined to amp and the other end ran to idrive this was to be the center channel. 

Boot roof speakers: as mentioned above the left speaker is joined to amp. For the right speaker i ran speaker wire from the left side and under boot floor following factory wiring threading through existing bundles to the right side where it was joined to the speaker wire just below the C pillar you'd never know it wasn't factory just the way i like it. Leaving the other end disconnected.

Yellow wire wasnt me lol i cut it and ran it in loom after the install 😅.

Rear door speakers: unfortunately the hifi option doesn't include rear door speakers and thus no wiring for any. I have left these 2 channels disconnected for now as its a big job to replace door wiring and connections via door plug. I may do this at a later date as ill get the parts to do so but it the mean time is more than acceptable.

Coding: removing option 676 and adding 677 to VO i also removed tv option as i used the MOST connection for the amp. While i was there i updated the usb screen to the nicer newer UI with album art.

So i already like the system but what a difference it made no more does the sound distort at high volume even with the missing rear doors and not all the L7 speakers etc. And with the equalizer im able to fine tune the sound to almost perfection.

Hopefully this helps someone or at least makes for an interesting read.

I've just done an E60, I picked up a L7 wiring loom from an E60 and while I had the interior out I ran all the speaker wires, including the rear door speaker wires to the door plugs, it was pretty easy since the interior was our and I had the original harness.

Since I didn't have a most connector in the rear I also ran the most cable to the rear also, ///Mproved if you need an additional Most loop to reconnect your tv option I have a few bits that will work, your most connector is shown in your photos just forward of the top of the amp, I've attached a pic of the Most connector in the E60.

 

I also changed all the speakers to L7 speakers including the subs under the seats.

Since I haven't got anyway to update the VO I took it round to BMW but they couldn't get into it, apparently it wouldn't connect into the system so they could change things.

I've fitted a few different modules, removed the AHL and fitted a LM2, HUD and also fitted another RLS, don't know if that would cause troubles with the dealer software.

So now I'm looking for someone that can alter the VO for me

Hey mate, great work must of been a mission. I have more most loops as well but as the analog tv doesnt work here im not worried about and just thought it easier than adding to the loop. 

Dealer coding is mostly limited by tech know how as most of their training is for newer models. Happy to assist with coding if you want. Im in west auckland.

Also you might like this its the M hud coded and calibrated to diesel rpm.

Yes it was a bit of a mission, but since i was adding a few things, including some wiring for some future additions I thought pull everything to bits and do it once. Also I didn't need the car as transport so it didn't matter that it took a while to get everything done.

I'm in Dunedin, can you still help with coding?

I'd be interested in the M coding of the HUD, the HUD I installed works as is with no coding. My HUD came out of a UK vehicle and isn't from a M5 but i understand it can be coded for M display. How did you get the RPM function working correctly?
