Vordon HT-869v2 - Control of the radio from the steering wheel

Hello.
I recently bought a Vordon radio and in the wiring I have 2 KEY1, 2 cables to be used to control the radio,
I have a Honda CR-V and there is no steering wheel control but I thought to add control, e.g. link (this is steering with Renault Scenic 1998)
I just do not know how to connect them to the radio
On the producer's website I found something like that link
Do you need a "driver" or something like that?

Thank you in advance for your help

I warmly welcome.
I contacted the Izotech company that produced the interface - I had previously ordered interafce to Kenwood, to which I replaced the original TunerList. I thought the interface was universal and would adapt it to Vordon.
I received the answer:

Renault Megane 2 from 2003
Joystick 8 function - roller operated with Kenwood.
Please give me the price of a new interface that would work with Vordon TH-869V2

So that PLN 129 and the roll will not work.
I did something like this (I added 5 resistors) and programmed Vordon:



I do not remember the resistor values - I bought a dozen or so in an electronics store after 15gr / item. They were from 1kOhm to 22kOhm, which I "drew" from the bag, I sold it.
In this embodiment the roll does not work, but the price is only 5 resistors.
Use the joystick from MeganeII - you can program 6 functions.
Probably, using other randomly selected resistors, you could program other functions by simultaneously pressing 2 keys.
