All of that is correct.

I'll also need wire(s) to connect to IBus somewhere in the back that run to the front dash area to connect to the Resler IBus adapter (so the USB connection can remain a short wire).

If the above paragraph is all correct, that leaves me with the question of.... what is the circled box below for? Is it just a wire junction box that I won't need, or is there some electronic magic that goes on inside there? It looks like your modified wire has something similar that you left intact:

AM.
The CANbus can be tapped in the front or in the rear, whichever you prefer. The AVIN 2 had it tapped in front on its harness and the current Android unit has it in the rear. The iBus wires should be tapped in the rear according to the current Resler instructions. They were written differently before so I did not run wires to the front... I will be tapping in at the nav monitor harness as Crowz did in his writeup.

That box is a combination fuse box and something else. There are windings and other components in there. Maybe a smoother/filter or something for the 12v constant??? I did not examine it too closely while I was doing my harness but it is more than just a fuse box for sure.

Like CW said that box is probably holding the fuse as th3 yellow wire is direct 12V source. Kinda big and obnoxious looking. Newer units have the fuse built in right under the connector.

I personally opted to buy the extension cable as extending 20 wires and wrapping it min 6 meters long did not sound fun.

In the end I had to extend 3 wires anyways for my iBUS connection and wrapping that was cramping my fingers lol.

So basically in my install the short quadlock connector is in the trunk and my extension connects to the other end, then travels all the way to the front long with the iBUS wires and FM/AM fakra extension wires and connects to the ISO behind the radio.

No tapping into any of the factory harnesses and plug and play.

The only tapping I had to do was my reverse lights to power my backup camera but that's for any camera you install.

Okay, I think I have this figured out. If I run the ISO extension that mr robot linked plus 3 additional wires for future IBus connection, I would only need to wire-up an ISO connector to the ebay quad connector pigtail I pictured in my post. That would allow me to connect a cheap radio to the vehicle harness and I should have a basic radio.

When I decide to upgrade to an Android unit, I would plug the ISO connector into the Android at the front, then plug the ISO/40 pin adapter that comes with my new Android unit into the extension cable at the rear (this should include the CAN Bus module). Connect that adapter to the vehicle harness, connect my three extra wires to Ibus, add the Ibus adapter behind the dash, and I'm ready to rock and roll. Oh, and I thought I saw that the antenna can be connected somewhere in the center console, so I don't need to run the antenna all the way to the back. Is all this sounding right?

Edit: I guess if I want a rearview cam, then I also need to run a video wire from back to front. So Mr Robot's ISO/ISO extension harness (or make my own), 3 (16 ga?) wires for future IBus, 1 (16 ga?) wire for future backup cam. And in my best Steve Martin voice, "and that's ALL I need. I don't need ANYTHING else!"

Does that sound right?

AM.

Here are all my links that I saved for the IBUS adapter knowledge and sourcing

https://xoutpost.com/1118186-post237.html

IBUS Interface for BMW cars

IBUS Interface order page

BMW IBUS App

http://download.speedy-pics.de/uploa..._interface.pdf

If you read through all those links you will be thoroughly briefed on where to get the adapter, how to connect it, and where to get the App.

Combined with Crowz "How To" in his signature and even a caveman like me could do it

For anyone that is interested, here is my experience installing my Eonon GA6166 unit a couple of years ago:

Thanks, semcoinc!

Just when I think I have this all figured out, I discover there's more I don't understand. Maybe my plan to put a cheap radio in for now, but with all the wiring in place for a future Android unit is not realistic.

First, a total newbie question.... what is the Fakra cable? I thought that was just the antenna cable, but your installation thread makes it sound like something else.

If I were to buy an Android unit right now, the one I have picked out is an Xtrons unit available on AMZ. Here's a pic of the back of the unit:

That doesn't look like a standard ISO connection to me. If this is some proprietary connection, then my whole idea of intalling universal wiring is kinda out the window.

Here's Xtron's extension cable which has quadlock connectors at both ends. That tells me that the Xtrons adapter that connects to the back of their unit converts to quadlock which means there's no universal ISO plug involved with their unit.

Maybe it's not worth trying to do a "universal" install and I should just order the Xtrons unit and proprietary extension cable. I guess I would still need to run the 3 wires for Ibus, a rearview camera wire, and possibly an antenna wire. Is there an additional "Fakra" wire I'm leaving out? I don't want to have to remove all the trim to re-run another wire later.

AM.

Fakra is the term used for the connector utilized by the antenna wires on the e53. Usually purple.

I wouldn't try to run a "universal" wire harness from front to back unless it was like that one above with the 4 quadlocks. That way ANY radio (android or not) you get can plug in up front.

AM,

My apologies for using the term "Fakra" to refer to the long cable usually supplied by the HU maker with their unit to interface into the BMW system.

As has already been suggested by crystal works, I believe it would be a huge waste of time to try to do some kind of "universal" cable. These HUs are not universal, in my view. There can be slight nuances of each HU maker and feature set to make each unit its own unique connection at the HU end.

I would suggest finding the nicest Android HU you can afford with perhaps 4GB RAM (2GB is sufficient but mo is betta ) and get the cable that the HU provider offers. Some deals include the connector long cord that must run from the rear (of a factory Nav E53) all the way to the front.

I suggest running all cables in one shot, your sub cable, your camera cable (and trigger wire) and any other video/audio for any AUX channel that the HU has and if equipped with a front camera/DVR, run that cable as well so that you are all done running cables for the HU.

My iBus connection was done at the front factory Nav blue connector cable.

I agree, it is definitely not worth it to try to run a "universal" cable, there is no such thing where these Android HUs are concerned. I certainly would not chance it.

So put this labor and money in once and only cry once as opposed to having a second labor and cry again down the road.

PS: Don't forget to change the factory 5 amp fuse (I think this is the factory fuse size) to the same size as is in your HU. If you don't do this when your unit exceeds 5 amps during an enthusiastic volume level, that factory fuse will blow.

Good luck with your choices.

Mike

Few (if any) e53 Android HUs use a standard ISO connector - there doesn't seem to be any standard of any sort used on these HUs.

Also, if what I've read here is correct and a. all USA cars use a rear mounted power amp and b. you don't currently have any sound from your OEM system, replacing or adding a HU may not give you audio, if the lack of sound is due to a dead amp in the rear. All the wiring schemes described here feed the HU output into the existing amp. in the back.

My car is different, with no rear amp at all - when/if I replace my OEM system, all the wiring (inc. speaker connections) are in the dash.

Well, that destroys my entire premise. I was under the impression that the Android units had built-in amps that would allow me to eliminate my factory amp. Thanks.... I think I'll go back to the basic radio idea again.

AM.
