I was at a complete loss of what to do when the radio/CD player in my Ford Escape began to experience an awful crackling sound that eventually ended in no sound at all. I could not even change the radio station - even if there was sound! After researching online, it became apparent that I would have to spend a LOT of money servicing my audio control unit (ACM) through a dealership. Luckily, I found Automotive Circuit Solutions mentioned on an online forum and looked them up. Their service listing was very straight forward. It listed the common problems experienced with many years of Ford Escapes - which included the problems I was experiencing. I called them to confirm what I was seeing/hearing with my vehicle, and they were very professional over the phone. I placed the service order online, followed the instructions they have on their website for uninstalling and mailing the ACM properly, and received my fixed ACM within a week. It has been one month since I have received my ACM from Automotive Circuit Solutions, and it continues to work great! I am so thankful for their quick, cheap, excellent service. A++
