Hello everyone,

I own a 1992 965, and I've been trying to build a nice stereo system in it. It has a Sony CDX-M630. Later I installed a 'rotary commander' (sort of remote by wire), an amplifier, 10 new speakers and a multi CD-player. Just last week I found an old automatic antenna from a Volvo 945, which I also installed immediately. Everything worked like a charm, it produced a beautiful deep sound. But yesterday something odd happened: while driving, the radio turned itself off, and then back on. A few minutes later it did the same thing again. Later on it began to happen more frequent. And when I arrived at work, the radio was going on and off every second... I couldn't do anything about it. There was no more sound, and I couldn't even turn the thing (really) off. So I pulled out the fuse. Yesterday evening I tried to use the reset button of the radio, doesn't work. I checked the fuse of the radio, which seems fine (should be, because the radio receives power). I checked the wiring, also OK. I pulled things out (antenna, rotary commander, ...) to see what would happen, nothing.

So, as I see it, there are two possibilities:
1. the €500-radio itself is broken, it has an electronic problem (it has a 1-year warranty and I bought it 1,5 years ago off course... very nice, regarding everything else works only on Sony-radios) ;
2. something happens with the power to the radio, but I don't have the slightest idea what to look for (some relay?).

Anyone? Many thanks.
