Hello, the problem is as in the topic. I bought a ready 8pin din to 3.5mm jack cable, but the radio does not see that something has been connected and I can't play my own music. It does not read CDs, neither does cassettes. I tried to make aux for the cassette board but it doesn't work at all. Somewhere on this forum I read that you need to solder the 12v cable from the radio to pin number 8 (picture) to make it work. However, I am afraid to do it without a previous question on the forum because the purchase of a new radio is average for me.
