Sup guys, totally new here, was sent here by a friend because Im having problems in my Scion Tc with this navigation system. I bought the car with AVIC-D2 installed already so I don't know much about it. The Scion Tc has a AUX reciever in the center console, but the D2 doesn't recognize it or something because I can't click AUX in the menu since it is washed out (prolly meaning I dont have it) Its either not connected into the system or broke? How can I check and what should I do.

 

Another problem, my steering wheel has buttons on it to control volume of the radio or w/e, but it doesn't work...do i need to connect that in somewhere to? Sorry if this is ridiculously long or confusing, but I'll try to explain as best as I can. Hopefully one of you guys/gals know whats up...

 

Thanks!

(ask questions if confused)
