[Solved] Connecting Chinese DVD Player 2 Din to Seat Altea XL 2007: ILL, PARKING, KEY1, KEY2/CANTX Wires

Hello,
I bought a DVD Player 2 din from China and intend to connect them in the car. However, I have a few questions about connecting to the car's installation:

- marked cable ILL is it to be connected to the clock backlight or the car interior?
- cable PARKING is to be connected to the manual brake switch?
- where to connect the wires KEY1 and KEY2 / CANTX ?

Hello

You have to start with the fact that in your car the signals, ACC, ILL, or steering wheel control are going over the CAN network, you don't pin it directly. The options are two:
1. Interface with CAN to analog.
2. Connect physically to the appropriate signals (easiest way is a fuse box)

I propose options two. Determine in the fuse box on which the wire appears + after the ignition switch and connect it to ACC on the radio, analogously + which will appear after turning on the low beam, connect to ILL.

Connect the PARKING cable to the power supply of the radio (for safety reasons, it should be connected to the minus which appears after manual removal)

For connecting a radio control from the steering wheel an interface will be needed which will convert CAN information for KEY1 signals KEY2. The radio probably in the SWC window has the ability to assign functions from the steering wheel (learning), vol up, vol down, seek up, seek down, etc.

This is the radio:

included is a box with a canbus description, probably to exchange signals from the steering wheel with the radio.
You know what the cable is for PARKING ? I thought it turned off the recorder.

This 20 pin radio cube is terminated with ISO 2, how do you connect the car to the car and the ignition switches off? Keys backlight reacts with lights in the car?

Parking is a function that allows you to watch movies from dvd, USB ... by design is available after applying the handbrake, so it's called parking (possibly connect this pin to ground, the option of watching while driving will be active all the time)

I haven't connected it yet, I want to find all the signals needed to connect first.

Added after 53 [minutes]:

Loose ACC and ILL cables come out of the plug from the radio and from the plug to plug into the installation.

After plugging in the plugins everything works. No loose cables need to be connected.
