does anyone here know how to .. rewire.. fix.. or whatever to get the antenna to stay down while playing a cd or usb or aux and only go up when changed to the radio.

i got the new Pioneer DEH-P6000UB

i know you can add a switch but thats kind of lame.. dont want to switch something to then change to radio .. ... maybe since i never really use it. would be okay but i rather not.

or.... any hidden antennas i can buy? no cheap stuff... more like from another car?

 

That unit does not support that feature. But you can either wire a switch to it or purchase a hidden anttena like you said. Metra makes some nice ones. http://www.metraonline.com
