I posted on the Electronics Forum as my Alpine Radio SEEK button is broken. I was given a link to a MB radio that started out at $40 and sold for $178 which was more than I wanted to spend because of a broken button that probably costs less than $1 if Alpine would sell it. Most W202 were delivered with Alpine radios, but some got the Becker. The way to tell the difference without removing the radio and looking at the back is to pull off the Volume knob. If it is smooth metal it is an Alpine. If it has ribs or spines on the shaft, then it is a Becker.
Which buttons are broken on your radio?
