Firstly can anyone tell me if the business cd/radio has any rca connections on the back. I bought a harmon kardon drive play and want to connect into the back of cd rather than through the fm transmitter. Does anyone know if it can connect in the boot where the cd changer goes?? Also on another tack when i start my car after varying intervals it beeps and says 0.3 degrees, what does this mean? incidentally it is a 06 2.5 roadster. cheers
