I received my autocal unit from Idaho Rob last night. First step is to copy the stock tune from my truck to the Autocal and email to Rob for tuning. Well the first time I tried it error-ed, don't remember the code but I unplugged the cable from the data link and tried again. This time it worked and began copying the info. Well when it was done my radio and door chimes were gone. Wouldn't work, I checked all fuses and found no bad ones so finally I disconnected the batteries for a min or two and when I hooked em back up the radio now works fine. Any clue what caused this??
