Audio Systems: XM - Roady XT, rear window antenna, nissan infiniti

Question
Hi Ernesto,
I just installed a Roady XT XM radio into my 2005 Infiniti G35.   It came with the "SureConnect" wire that attaches to the top wires in the rear window antenna.  It is working fairly well, but the problem is that when it is connected, my AM radio will not work - I just get heavy static.  If I disconnect the Sureconnect wire, the AM radio works fine.  Any thoughts as to why and how to correct this?  I do like to listen to AM talk radio.  thanks for any help!
Karl

Answer
the fm signal block the am frequency
if you have a SAT button ue this interface to feed audio in to the radio the sound will be of cd quality
good luck
