Skoda Fabia 2001: Pioneer MVH-160UI Radio Auto On/Off with Key - Wiring Configurations

Question

I have a Pioneer MVH-160UI radio. I would like it to turn on with the key and turn off after removing it. Currently, I have to turn the radio on and off manually. The manual states that, depending on the car, red to red and yellow to yellow or, conversely, red to yellow and yellow to red. I tried both, but the effect is still the same - I have to turn it on manually.

In conclusion, swap that black-blue under gray-white with brown-red insulated somewhere in the back.

Top up the fuses, check for loose wires behind the radio. I don't remember exactly, but there are cars with a triple fuse socket. It is translated depending on the needs, whether the radio is keyed or not.

piotrek22101 · Answer

Check if the red and yellow from the radio come into separate wires in the car's installation. It is probably factory-powered that is a constant plus only.

sk700 · Answer

100% not, the logic of ignition only came cheaply in factory 2 and derivatives. Provide a picture of the wires in the black factory cube. Check with a meter whether any power is lost after removing the key, remember that it is necessary to completely remove the key from the ignition switch, just turning it is not enough.

piotrek22101 · Answer

It is a converted installation in 100%, you can see the red connecting connector. Probably he gives a plus constant on both pins.

sk700 · Answer

I do not deny that it is mixed up in the installation, my answer concerned the factory condition, just like the quoted fragment.
You are right, I did not pay attention to this red connector before, either the power supply shorted or the power supply connected to the antenna, but I would rather opt for the former.

I took measurements and the voltage on yellow and red is constant, regardless of whether the ignition is on or not. However, I disconnected the red cable from the black and blue cable, which were connected with this pink connector. I only checked the voltage on the red one. It is not on it, whether the ignition is on or off. I didn't make any more measurements because I don't know what to do next.
Illustrative photos below:

Take a picture of this black plug from the installation side so that you can see the colors of the wires.
At this point, the wires that connect to the yellow and red go into this wrapped bundle? If so, possible damage to the car and the previous owner combined it to be overcome.
Also check the fuses from the radio on the side of the dashboard.
What is this extra fuse? Where is he connected?

Jachuw90 · Answer

I will take photos, and this additional fuse is on the red one, which was connected by a connector to the one shown in the previous photos, i.e. to the black-blue one.

In some versions, after removing the key from the ignition, the light in the headliner turns on or if the car closes itself after exceeding 20 km / h, the door opens after removing the door - is this happening to you? Everything points to the lack of a plus after ignition and to work around the problem at the cheapest cost.

Jachuw90 · Answer

Yes, the light comes on in the headlining after removing the key. And the locking of the locks after 20 km / h I have disabled with the VAG

sk700 · Answer

So the ignition switch and its cube are working - you have to lead to a situation where one plus will be lost after removing the key. Start with the fuses on the side of the board. How do you find which one you can check with a meter, not by eye

Jachuw90 · Answer

There is something like that - I don't know what it is either ...

sk700 · Answer

The power supply is these black wires with a blue stripe. As I said, you need to find out why there is no voltage on one of them after the ignition. The blue cube is a changer or its emulator.

piotrek22101 · Answer

1 - white and purple cable - GALA signal that controls the volume of the radio depending on the speed of the car,
2 - missing car cube without hands-free installation - MUTE radio mute signal by phone,
3 - gray and white - K-BUS radio diagnostics, e.g. with VAG,
4 - brown and red + 12V from the ignition switch,
5 - black and blue + 12V Navi SAFE anti-theft signal,
6 - gray blue - radio backlight
7 - black blue - + 12V constant from the battery - memory backup,
8 - brown - (-) mass.
Two black and blue are the same power supply.

Jachuw90 · Answer

I checked the fuse from the radio, it is working. Oddly enough, according to the list of fuses, the fuse from the ignition system is missing ...

Jachuw90 · Answer

And it does not matter with which black and blue do I turn? And how to disconnect this cable from the ankle? And the red-brown one insulated at the moment - on it I checked the voltage with the ignition on and off and there is nothing, zero. PS. sorry i was wrong on that red one on the back there was no tension. I did not check the red and brown one. So I have to replace these, yes? : PS 2 ok, I already know. Not the black and blue one, but the other one Added after 1 [hours] 18 [minutes]: Thank you to everyone, just like the sk700 said, yes it was, cables changed and everything works as it should be
