A powered USB hub should do the trick. Having a non powered USB splitter will not do any type of packet switching and routing to avoid collision detection, therefore cause data collisions in your head unit. A USB powered hub helps correct that problem, might not completely eliminate it though. Your head unit firmware might not support multiple USB connected devices. If that's the case... SUGGEST IT TO GM... that would be great! =o)
