If you need to update the unit or downloads tracks, one thing to wary off is the RS232 serial port issue. The 196 is getting on a bit (5+ years old design) only supports the old-style 9-pin serial conenctor to your PC, which as I understand is longer in the current global PC spec so you'll start to see them disappear. Apparently having asked on another forum this week (thanks Ray P) a USB-RS232 converter will work. The 96C is USB.
