I have a 97 W202 with the optional built in cell phone (it was there when I bought it)

My question is this. when Im using the CD changer why does the antenna go up? I can understand with the radio but why the CD.

First I thought...maybe because of the built in phone...but then the phone is powered off?

Anyone have insight on this?

Your antenna senses power from your radios head unit. Power on = up, Power off = down. Your antenna isn't smart enough to know what function your radio is performing. Work around? I dont know, I have never heard of one. Sorry. Paul

Thanks Paul, always the one with the great advice.

You might try getting Stevebfl's attention. With my 1992 W140, the antenna was staying up even with the radio/head unit turned off. I asked them to fix it and they did something and now the antenna only works when the radio/head unit (including CD mode) is turned on. I didn't care about the cell phone working because as nice as it is, (a) it's analog and (b) you can't take it with you.

Hope this helps....
