Wondering if anyone has had the following erratic behaviour? Recently I tried to engage my CD player of my 99 E320 4 Matic...message on radio said "NO CD CHANGER"...now I know I have one...The MB telephone will also not work during this problem. If I pull the fuse under the rear seat and reset it, they work fine for a period (as long as I have the cd player on). Additionally, the little viewing panel on the radio area appears to pulse dark then light both when it is working and when it goes out...the speed of the pulse changes. Any ideas what might be causing this erratic behaviour and how to correct it?
Thanks
