please help control tape problem

Hi guys first! Let me explain my problem, someone help me. 2004 model partner 2.0 owner I have a problem with the tape and remote control since I bought my car. But when the sound starts to increase, I turn on the remote, or mute it, and the sound starts to increase automatically from the remote. Thanks...

There are two things that come to my mind. Either your tape needs to be reset in some way, as if there is an instability in its system. Or the volume control key of the joystick may be stuck somewhat and raise the volume constantly, try clearing under the keys. You can remove the electrical connection socket from the back of the tape, wait for a while and reinsert it. I think the other sockets can be removed and cleaned and put them back in the same way, maybe it may be fixed. However, if it does not improve with these, it may be necessary to introduce the tape to the vehicle again at the service. For now these come to my mind.

I will evaluate what you say, only when the control that confuses me is not working, the sound stops when it works. Why does the logical thing you say about the keys alone does not work for a while, but then comes on automatically.

I think this may be related to either system instability or back connections, as I said.
