Everything was tied to his stock head unit is why it was expensive. He had to buy other items to retain functionality like the steering wheel controls and a kit I believe in order to upgrade to an aftermarket hu. If you think his price was bad, my car in my avatar has everything plus the HVAC / heater, steering wheel controls, etc tied into my stock head unit. Mine would cost upwards of $1300+ to get a kit and retain everything.wow thats a lot for hu.. do u have other equipment?
