Hi, I'm new to the forum but have used detectors since I started driving. I've had all types of detectors from Fuzzbuster's, Uniden's, Cobra's, PNI's and currently my favorite Beltronics. My all time favorite is the Vector 985 because of all the features and sensitivity. I just purchased an additional 985 off ebay that looks brand new and came with all the accessories, aluminum storage box, and original box. The guy selling said the speaker stopped working and he did not want to fool with it. I got it for $20 and had a speaker to install when it came in. I installed the new speaker and powered up and still no sound. I checked the original speaker and it is working. Bel does not service this unit anymore so does anyone have an idea of what is wrong. I cannot get the case completely apart and don't want to pry on it without knowing what I am doing. I would really like to fix this unit.
