Car Sound electric Error

[triplenetz]

Thanks for all the reply. I went to wrecker and get the cable there. One thing i notice after setting back everything is Dim/Illum function is not working anymore . Before that i can see the "in car " light base on the car head light setting. Now everything i opened the Car headlight it will always go bright . no dim anymore . Any idea why it's happening now ? . Hope that make sense i m not sure how to explain it . but usually the "in car " light will go fade first before bright . Now it's bright only and no fade light anymore .

Anyways i bought the new headunit during ebay promotion and now i want to fix all the problem before putting new headunit . Thanks again !
