The problem is. We all have the same issue. Different car different pioneer head unit. My old one which I had switched out did the same. When driving the head unit turned off. My personal experience was if I hit a bump it turned off or on. After a month or so of this it stop working completely. So I replaced with an updated one. Not even two days it did the same however I notice for myself I was playing music with the volume up. It’s been a week and it been on 11 or 12 volume. No problems yet. Btw, I put heat shrink tube on all the wires thinking this can eliminate the problem. I checked the fuses as well. Any help would really help.
Thank you in advance,
