Yes, I used the blue tuner flying lead.

Are you sure you didn't use the blue amp remote line? That's a different wire.

Your description of the symptoms is consistent with someone who has used the blue amp remote wire to power their radio antenna.

The blue tuner wire is only on the extension cable for the tuner module.

Also, make sure you are using 2.0 software, which behaves differently with regard to the antenna than the 1.03 software does.
