… I left it on Line In for about a week or so without touching the satellite radio, and then found that when I pressed [AUX], it would not leave Line In, and nothing would happen. The dealership asked me if I had used an iPod with pirated music, and said that the pirated music likely contained a virus which had corrupted my car’s computer for audio, disabling satellite radio. The system needed to be taken apart and ‘cleaned and reprogrammed’… $249.88
The technician stated that Fords run on Microsoft, and the antivirus is programmed to freeze when it detects a virus in a foreign object (ie song or picture on my phone), and that it detected this through the Aux cord when it “communicated with and read my phone”. He claims there was no virus in the system but that I “could imagine how bad it would be had it not frozen and let the virus in”. Also told me this is very common and in fact he had two in today. I asked him for a print of the test he ran when he plugged into the system and for a copy of the error code/statement and he said there was none because the aound system didnt communicate with him at all. I asked him how he knew what was wrong and he simply stated because he does it all the time, and he knows.
