Not exactly an answer to your question, but an example of what I did for security to thwart theives. In my previous car I had a high end head unit ( the eclipse double din lcd if I recall). I took an older double din factory radio ( tape player not CD--nobody's wants to steal a tape unit) and dremeled just the front of it off. Now, when I leave my car, I would put this faceplate over my radio and It looked completly stock. It depends on the style of dash you have, but for me it worked great. Just an idea.
