Cruise control, climate control, & heated seats simultaneously stopped working
 

2001 Audi TT Quattro. Cruise control, climate control, and heated seats all stopped working at the same time. Also I have to manually turn off the radio now, it does not shut off when I exit the car. I can find nothing online where someone has had the same problem, any insight would be greatly appreciated! Also all the fuses and relays have been checked.
