When chatting with coworkers about cars at my group holiday party recently one of my coworkers mentioned trying to install an aftermarket cruise control package and the car would no longer turn on. He put everything back the way it was and had it towed to the dealership under warranty. Turned out he had fried the APU card. Even after this thread, I am not really sure what to say to someone who does this. I am not sure he realized he was admitting to committing fraud.
