I have an Alpine system installed into my 560SEL. It has been working great until yesterday. While I flipped open the display of the navi, a blue screen showing that it's updating the software and do not remove the DVD until you see the Alpine logo. However, it repeated itself over and over without end. Anyone know what it going on? or La Jolla Audio? You guys have been very helpful in the past.
