Let me start from the top. Upon entering the vehicle, I should hear sounds/alerts from the car because I currently have the tri-fecta of lights (DSC/ABS/Park Brake) .... Nothing! No warning chimes whatsoever (seatbelt, etc.). Of course, I have no radio either. FM, AM, WB & Memory are all still lit white, but CD & CD changer are greyed out. I knew about the CD changer because I bought the car without a magazine. So, basically the change is now that "CD" is faded out. The unit still accepts & ejects CDs but no function can be clicked on to operate except Memory. Bass/Treble, Fader/Balance & Logic 7 are all still lit white but I can't access any of them. All this began after taking receipt of the car after a detail. I am currently seeking options to have them accept blame but that's neither here nor there. I have NO MUSIC!!! I need this solved like yesterday. My question is ... Is it definitely my L7 amp or could it be the ASK unit. I'm close to pulling the trigger on a $599 "Buy It Now" L7 amp on eBay but I wanna be sure. From all the behaviors that I've listed .... can anyone tell me what the culprit is for sure? I'm not the most handy & attempted to pull the clips out of the trunk liner yesterday but I felt that I was breaking them so I stopped short. I just need my music back so I can maintain sanity while I focus on the tri-fecta of warning lights. (Most likely my DSC module). Please help fellas!! Thanx in advance!
