Antenna Not Working
I recently attempted to install an in-dash AM/FM/CD to replace the factory in-dash AM/FM/Cassette in my 1985 300D. The power antenna was working before I started, but no longer works. I have checked all the fuses in the panel on the driver's side firewall under the hood and all are okay. Are there others?
Thanks,

whoovers got it
allmost all stero head units have an accessory antenna signal.the wiring diagram that comes with the stero defines it,it will send the signal to your antenna relay to raise/lower whenever you are using the am/fm function.you are going to have to find which wire is used on your MB for this function.hopfully you have a wiring diagram and beware of german colour coding acronyms,you have to translate to english or nothing will make sense.did you use a adapter plug to intigrate to your factory harness?or are you splicing in?

Make sure you connected the antenna wire from the radio to the blue wire on the vehicle harness, if the antenna was working before the radio installation then either it got miss wired or something is not plugged in.
