Radio/tape Cd Player problems of the 2003 Volkswagen Jetta

Am radio not working. Fm radio has limited range.

Recently the radio in my 2003 Volkswagen Jetta wolfsburg edition stopped working. At first the radio station was displayed but I was unable to get any buttons to work except the eject button, the volume knob, and the on/off button. The last radio station I listened to was displayed but no sound could be heard. I started to look for help on the internet, possibly a fuse or something simple but what I found was completely the opposite. According to several websites, the radio has an internal defect which fries the radio when the battery starts to get weak. I work at a Cadillac dealership so I tested the battery and it tested marginal. I checked with a couple vw dealerships and they both told me I would have to replace the radio. I just received my aftermarket radio, which I ordered after hearing horror stories of replacing the radio with an oem unit and having them go bad again the next time the battery went dead. I still have the oem radio, and will hang on to it for while.

Out of no where my radio on my 2003 Volkswagen Jetta wagon stopped working. All I got was static on my radio. After reviewing several vw forums, I found out that my radio antenna had corroded inside. I took it apart and cleaned all the corrosion and found that the main wire on the circuit board was broke. I had to solder a new wire onto it. Many vw owners are complaining about this same problem, but Volkswagen will not do anything about it. A antenna should not go bad in a three year old car.
