I installed a SmarTenna model 301 in my '95 NSX. The antenna control function works fine, but the portion of the SmarTenna that goes between the CD player wiring's DIN connectors was picking up noise (noise that originated in the CD changer transport) that you could hear in both channels when playing CDs. The noise was fairly low in level, but loud enough that it wasn't masked by the music on most CDs. It was annoying enough to make me not want to listen to CDs.
I note that the DIN connectors in the CD changer wiring are shielded, and that the SmarTenna piece that goes in between is not; I tried installing the SmarTenna connector and wrapping that whole area in aluminum foil, and that has fixed the problem (it's a little touchy; I had trouble getting it to work).
A week ago, I emailed Bryan Zublin (SmarTenna maker) asking about this but haven't heard back yet.
I doubt I'm the only person who has encountered this problem. I'm interested to hear what others have noted, and done.
