Hello friends,

 

I bought my first car: Skoda Octavia 2.0 diesel, 2005 and decided to get aftermarket radio fro Aliexpress

 

When I read through item description and characteristics I decided to buy and faced an issue with sound. After hours on YouTube I almost gave up and before sell it or go to the car service want to ask question here. Lets hope that someone can help me out.

 

Here is my troubleshooting:

 

1. I took "test speaker" and connect it to aftermarket harness - Sound coming from test speaker

2. Connect "test speaker" to factory harness - Sound coming from test speaker

 

Therefore the aftermarket radio is working and signal travels from aftermarket to car harness

 

3. I took the multimeter to go through with all 8 pins on factory harness which responsible for speakers in the car

All eight speakers pins shows around 100 Ohm each which means there is an factory amplifier somewhere but aftermarket radio ain't triggering it

If there was a speakers without amplifier the resistance would only 4-8 Ohm (i am not electrician)

4. Measured voltage for 12v "Accessory" - all good in there

 

I do have blue/white wire with "AMP CONN" label on it but no idea where to connect it

 

Below I attached screenshot of my radio and after market radio

On after market radio you can find "Audio cables". The  "AMP CONN" is located on it

 

QUESTION:

Please tell me how to turn on amplifier? Where to direct supply voltage or activate it  with a command on the can-bus?

 

Thank you

 

Regards,

Vik

Have you connected what they call the protocole box?

 

Are any other canbus inputs being displayed on the radio? - doors open, reversing sensors, steering wheel controls etc?

 

If it was not sold as a direct VAG replacement (which the faceplate shape indicates it is) then you will need to select the correct manufacturer comms protocole in the factory settings, you will have to ask the seller for the factory code to access them.

 

I dont know where the amp is, I have fitted two cheap versions of your radio to a 2006 Octavia and a 2015 Yeti replacing a similar OE stereo and had no problems with sound.

 

You may in any case need a later revision Canbus gateway if you have battery discharge problems.

Thank you for the reply

 

Yes, protocol box is connected and transfers all information from the car to the tablet radio like open doors, fuel level, battery charge and etc

Everything is working apart from the sound ...

 

I will contact manufacture to get in to factory settings
