Constant Alarm on Radar Detector

[PPatterson]

For several months my Valentine radar detector constantly reads 7,8,or 9 alarms. It works normally in other cars. The Valentine website says "see your dealer." It detects bogeys on all frequency bands (maybe not laser). Would anyone know or venture to guess what electrical component in my car is most likely to be causing this? I have a "97 C230.

Thanks in advance
