Report "I have a CDA-9855 Alpine head unit. It worked just fine when removed from my prior vehicle (05 VW Golf). I just installed it in an 01 Land Rover Discovery II using a wiring harness adapter so no cutting or splicing was involved. The unit powers up, and the radio works and there is sound coming from the speakers, but when I insert a CD or plug in the iPod through the KCA-420i there is no sound, but it displays what song is playing on the screen. I have tried hitting the reset button on the front face, but nothing changed other than reseting everything. I have also made sure the internal amp setting is turned on. What should I be looking at?"
