I recently tried to install my Panasonic CQ-C7203U in my new jeep out of my old car - the radio works perfectly fine, but when i put a CD in, it restarts the whole head unit, and then shows for the artist and title "NO TEXT", and says it's playing, but doesn't put out any sound.. I'm thinking it may be some sort of security feature, but in the unit, security is set to "OFF"... Anyone have any ideas about what's going on??
