Hey guys! Alfa 159 (2010) MP3/BLUE AND ME. So long story short I had some stereo shonks come over and attempt to fit a new HU for me. 4 hours later they tell me the unit is faulty and needs replacing. He said it was working, then all of a sudden it wasn't.... Also popped the HIFI fuse under the bonnet. I told them to put everything back the way it was, including my stock blaupunkt double din mp3. They did. Except.... I turn on the car and no dice with the stereo...... Not even a light. I pulled it out and checked all the ISO plugs fuse in the back of the unit all ok. Now I can't get hold of the guy!!! He told me before he left all was good. Also said that he didn't cut any wires or do anything like that as he got a harness. No CAN BUS errors or anything like that. Checked fuse in back of unit and under dash and under the hood. HELP PLEASE HELP!!! I tried to get people to do this stuff for me so I wouldn't have to go through all this!!!!
