7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

You can use any of the 2 or 3 antenna connectors on the tuner: X13349, X13348 or X16662.


This is the tv areal in the rear window:

Thanks vibbelito, anyway, I don't think that these connectors are based on antenna diversity.
So I'll have to find the good one manually but that's OK, there are only 3 connectors ... not 50 !

I'll cross my fingers for the 720p thing to be fine with the E65 digital tuner

Sorry, for showing incompetence, but isn't there a tuner which could receive all digital channels available and then capable of transmitting those signals of all the channels. So the e65 module could just receive it over standard antenna. Asking because in my country e65 module is useless since.introduction of mpeg4 stabdard for terrestrial TV. I guess the simple answer is that no portable device can retransmit all channels. That's my part of interest in this

I have been looking for some device that can recive H.264 and MPEG4 DVB-T2 and just re code the channels into MPEG2 DVB-T1 passing them on to the original tuner like the one available from bmw that does that conversion from MPEG2 DVB-T1 into analog channels when that switch over first happened. Unfortunately there doesn't seem to be any converter this time around yet.

They have discussed that on the 7er-forum.com

http://www.7er-forum.com/forum/showthread.html?t=221633

But such a device would be neat with a video input combined with it. Hopefully it will come around soon enough.

That multimedia box seems nice, and I already heard of it in the past ... but the price ... WOW ! so expensive, you can't even imagine !

Actually, I have been keeping some parts from my 2 last Logic7 amplifiers
I'm talking about the MOST bust connectors ... so if there are technical documents about that data bus/protocol, I may be able to code some software on a platform like RaspberryPi, ASUS TinkerBoard (or something even faster).

One good thing about those 2 platforms : they are CANBUS compliant (with additional hardware of course), but I'm actually working on a project with these for building an man-sized helicopter.
So, I think I can handle that too


Cheers !

Actually MOST bus informations are available from (mostly) VECTOR :
Anyway, hardware related to this data bus seems pretty locked down @ automotive brands.
Finding useful informations / coding libraries / hardware / etc ... seems impossible

I don't know if you have seen this website where he has done something with a multimedia player to replace the DVD changer
https://www.mein-bmw-rudel.de/index.php

This document from bmw about E65 bus systems describes much about the MOST bus

Almost **** my pants thinking i bricked my rear monitor when I measured frequency on two of the pins that I thought could be video output. That turned off the screen making it unresponsive to anything not wanting to fold down or anything. But luckily it came back to life after I unplugged the canbus connector and reconnected it

Anyway, 5,026V was I able to measure between the two same pins if that's anything to go on.


And the resistors there are 4,722kohm

Does that mean that it is not an LVDS output?

Hum ... maybe first you might want to find the ICs datasheets and rely on them to find the others RGB/LVDS inputs...

I'm pretty sure we can send video signal somewhere ... buuuuuuut, audio part will we tough to get simultaneously.

Anyway, I know that the GPS module (NAVI) embeds others video inputs ... for sound, it might be tough too, but not impossible.

I know that audio is ADPCM 44.1Khz mostly and flows on MOST bus.
I'm pretty sure that I can arrange a replacement video module if I have the time to ... and keeping idrive control to fulfill your dreams all ***x1f609;

But, this is a pretty damn work & time that I might not have for the moment.

Dear everyone, I just tried to use the modulator and for now, it is a fail.

I couldn't access the antennas connector to plug in the output of the modulator.

So for now, let say it is just a matter of physical connections.

So now, I need to find a tv antenna cable (the ones with a screw), cut it and use a FAKRA antenna connector that I received with a Bluetooth TCU I bought recently (finally I may find a use for them ***x1f642; )

Will keep you in touch.

NB : i'm fearing something else which is the fact that that E65 was equiped with the analog tv tuner initially and I just swapped both tuners without changing any option in the MMI.
I remember having read on a forum post that maybe there is an option to code inside the MMI (something like «*digital_tv*» == «*aktiv*»).
But I can't figure it out where I found that information.

If you can help me on that it might be less time consuming =]

Cheers !

FOUND IT !!!

Option is this one : TV_DIG
And it should be set as «*aktiv*» instead of «*nicht_aktiv*»

The thing I posted digging around inside the screen is for a side project for a video output from the MMI so that the 6.5" screen can be replaced with a bigger one

I actually have that set to nicht_aktiv since I have both analog and digital tuner called hybrid tuner. I think that setting it to activate locks my tuner in digital mode only. If set to nicht_aktiv I can get both analog and digital signals at the same time if there were any.

Or at least I think I have it set to nicht_aktiv

On regards with the video output I did another try with converting the RGsB signal that runs into the MMIF but no luck. My hacked up VGA cable with all video signal earth connected together and the vertical and horizontal sync cables connected to the Green wire since the signal in the car is sync on green. But still my converter showed no signal. It can have something to do with that the converter converts the VGA signal to HDMI and then I fed that HDMI signal into an HDMI to AV(CVBS) converter and then into the screen.

I have tried that setup with a VGA output from a PC and that worked. But I don't know how smart the vga converter is, if it needs to see the DDC and EDC channel to sense that there's a signal present to turn on the conversion. my other cheap vga to cvbs converter cable was pure junk as I couldn't even get a stable picture from my PC and in the car it was unstable and black and white and only worked when shorting all the rgb cables. So I'm stuck there with that

This may well be a working lvds to hdmi converter or mabey being able to output the original idrive interface menus.

https://car-solutions.com/en/video-i...-2002-2008-my/

Take a look at the board you get with it:



On the input side you take the output from the original screen driver board and connect it to a converter cable that then feeds the screen signal into this board that actually incorporates one of the chips recommend by TI support to convert lvds to tmds. And then it outputs the signal through an hdmi port that they call digital rgb.
So maybe it is actually an hdmi signal it outputs.

Unfortunately that product has been discontinued:/

Still haven't tried it for now, but seller answered me on for output resolution conditions on Aliexpress :

input resoution>=720p***65292; output resoution=720p
input resoution=480P/576P,output resoution=480P/576P
input resoution=480I/576I,output resoution=480I/576I

So basically the output resolution depends on the input resolution ... interesting, but actually it seems a pain point to me because it means that the module do not offers downscaling feature for video streaming.

I understand, I haven't had much time myself as life got in the way.

That's pretty interesting that it doesn't scale it
Hopefully our reciver is able to downscale it instead. It already down scales the 576i to 400x240p I believe. It it also able to scale down the resolution of 640x480p that it receives via CVBS plug from the night-vision electronics.

That's a pretty nice argument here.
Maybe downscaling 1280x720 (720p) can be achieved too ... ***crossing fingers***

I have ordered the bigger model called EMB220T so we can see if it actually has any features that we can take advantage of. It has an estimated delivery date of Oct 11 - okta 20. So hopefully I can take a look at it then.
