my 9835 had a black plug on the back which was for the radio. on the 143bt there is no such thing and hence my am/fm isn't working. its installed in a kenworth dump truck and the truck itself has the black radio plug that looks like a giant 3.5mm jack. but there is nowhere to install it on the 143bt, is there another way to get the radio working?
