Radio whine
Had my dealer install what he called an IPod adapter on my '05 987 some time ago. Never used it much, but just started using it. I now get a high pitched whine that changes w/ engine RPM, when using an MP3 palyer. Basically what they installed is a RF aux. input that plays thru a radio freq. Any ideas??? Back in the old days, this type of noise was usually fixed w/ a choke coil, but no one seems to have heard of them.

Most of these FM based transmiters suffer from interference. In your case probably from the ignition wires. I don't think its worth the hasstle, as sound quality will never be very good in the best of cases.

Orc, thanks for the info. I had thought this would be better than the wireless transmitters I have tried. They did not seem to have this whine, but faded in & out. Do you think that changing the location of the power wire might help any???
