We recently purchased vehicle, radio worked fine. After having it sent out to be cleaned, radio and components work, but there is no audio coming out.
Husband is a mechanic and very electronically savy but is totally stumped. Any help is appreciated!
I have a 1998 e 430 the radio is totatally out the fuse seems fine. The battery was recently changed but you can't enter the security code into the radio because it does not come on, any suggestions
