cdjr:using_player[mp3]

I am trying to get the map command "cdjr:using_player[mp3]" to work so that my Yamaha reciever will automatically switch to the Tape 2 input upon selection of an MP3 file. I have created the device file in EZ Learn, named the device file in CDJ Options, and edited my MAP file for the cdjr:using-Player[mp3] but it still does not work. Strange thing is that when a MP3 file loads it switches to my phono input. I tested the device file for my input command and it correctly switches the reciever to Tape 2 not phono.

Any ideas on what I am doing wrong. Other device file command work okay such as cdj volume up/volume down.
