Steering wheel heater

Since I’ve been phaeton owner for a few days, there would have been some questions. 1. Steering wheel heater switch is available but no function, no error message, 2. Set the chassis to sport always back to normal. Do I do something wrong 3. Glove compartment is a plug next to CD changer, I can connect hard drive, USB memory when I buy the cable 4. Switch TV free while driving
