Answer
Hello Todd,
By what you mentioned about hitting a bump and the radio will turn off, I would say that somewhere you have a defective connection. This defective connection/s may be in the wiring or it could be inside the radio? Double check all your connections to the radio and if you have a wire connected directly to the battery like some installers do, check that for tightness. The power wire that may be giving you this problem is the switched/ignition wire to the radio, since the station memory isn't effected. You might also check the connections between the face plate and the radio for dirt on/between the connections if this radio has a removable face plate. if you need to contact me in the future you can Email me direct at: tdeser@zoominternet.net
