One more problem that I noticed: the radio reception (AM and FM) fades in and out on at times. I am not sure if this is related to the antenna/antenna cable or the head unit. The antenna is located in the rear window on the 98 models and up. The cd and cassette work fine.
FYI, I replace my battery last night and everything is back to normal. I had the original battery tested and it shorted out under load.
