V35 350GT8 Sedan

Hi, I have a Panasonic CN5000 TV/SatNav unit in my sedan. Do I need to throw the whole lot out (except the Pana Screen) to get the TV working?? The system has a hard drive and SD card slot, was hoping to load music onto it, just have to figure out the translation!! Shame that the Sat Nav etc doesn't work here.....quite and impressive system
