Your CD player is 10 years old and apparently very tired. My advice is to replace it with an aftermarket radio/CD player (I never play tapes so I skipped those models). I picked one up at Best Buy for $160.00, installed it myself (very easy) and I love it. It even came with a remote control that I mounted to the steering wheel so I can change stations, songs, volume, etc. without taking my hands off the wheel.

By the way, you can still purchase a brand new stock CD player from Subaru...they cost $500.00 (that's JUST the CD player!!!).
