difficulty to connections

[picolo]

Hello everyone
really not very clear the documentation, I have a lot of difficulty to understand.
I often make electrical connections, but the documentation is not clear
I hope you can help me.
I bought this interface for my A6 4F MMI 3g Basic

https://car-solutions.com/en/video-inte ... th-pas.php

+ 12 / gnd power supply, ok, but the questions remain!
on the image that I present to you, all the questions are present in image.

1) cam rear , I installed it, I plugged it in before receiving the interface, this camera is powered by 12v as the vehicle goes into reverse.
question, plugged the connector "R-CAM"? or not ?

2) The interface wires, yellow, purple, gray and white, they plug or ?
what connection in the car ?

3) Cabling "CAN" ok, I use "HS" if no good..., "LS"
I do not cut the original wires, I connect them "green / brown (command) with green" and orange / brown (command) with green / brown

4) RGB-in connector, why ? necessary ? , wiring in the car ? or ?

the questions in pictures :

Hello.
You may power it up(ACC and GND wires) from the cigaretter lighter.

1. Rear view camera can be powered from the R-CAM socket of the video interface.

2. F-CAM-DET, SAFE wires are not used. MMI wire(picture attached) is used to switch video interface inputs with the OEM NAV button(on MMI controller). REAR wire should be connected to the reverse lamp +12V wire if CAN connection is not used.

3. Do not cut OEM wires. Just strip them off and connect CAN wires from the interface to them.

4. RGB socket is used to connect an aftermarket navigation box.

thank you, I must be able to properly wire the interface.
I have all the necessary information.
thank you very much

that's one of the reasons I chose carsolution.
his technical help and his forum

[Yuretz]

We are glad that we could help you and greatly appreciate your feedback.

I'm on vacation, I can finally start the connection of this interface.

REAR wire should be connected to the reverse lamp +12V wire if CAN connection is not used.
ok...

more exactly, if I do not use CAN wires.
what to do ? ? ? ....

ok ---> ?

thanks.

Find the OEM wire on which ~+12V appears when the reverse is on and connect the grey wire from the video interface to it.

[picolo]

OK no problem, the gray wire of the interface receives + 12v when the reverse gear is engaged, to display the reversing screen

it is a solution if I do not want to use the CAN communication wires.

and in case I want to use CAN wires? , I do not plug the gray wire. (ok ?)

the transition to the screen from the reverse then to the video screen and then,
the MMI radio screen will be with the original controls, which is much more convenient.

in this case, finding the CAN wire on the Audi, can be a problem right?
Can you see these CAN sons in these photos? thank you

Yes, you don't need to connect it.

CAN connection should be done behind the climate controlling unit as it's shown in the manual https://car-solutions.com/nfs/product/8 ... al_2.0.pdf , page 12.

[picolo]

ok, to summarize, if I plug the CAN link of the video interface to the CAN link of the AUDI? you do not need to connect the other wires of the power connector ....
except the + 12v power supply (red / black) ... true?

I found another more accessible place to connect the CAN link.
(nothing to disassemble)
I will post photos. (It can help other people)

True.

Hello Yuretz
have you experienced a problem like this ...
the CAN Audi, not recognized by the video interface?
thank you

[picolo]

why the question ?
because, I connected to the CAN network of air conditioning, as noted in the manual, without success!
CAN interface cable H hs / ls, then CAN L hs / ls the same! no result !
it is obvious that there is a CAN communication problem on the Audi A6 Facelift!
(2010).
I am a little disappointed, to compensate, I used the +12 signal of reverse.
it is necessary to forget the controls of the vehicle to use the video interface !!

Have you tried all values in CAR MODEL after you've connected to CAN wires behind the air conditioning unit?

[picolo]

Hi,
yes, everything tried, tried also to reverse the CAN cables (with some fear ... some cars do not like that!)
no dialogue!
no problem .... I will do with the "classic" way without CAN.

just a note, I posted elsewhere in the forum, to have the audio with this interface, you told me that carsolution had no answer!

here is the solution, if you want audio, very easy, I did it! follow the guide !
to have an AUX on Audi (2010)
