I just installed the USA Spec PA15-INFI ipod interface in to my 06 non sat g35coupe. When I turn the car on "Telephone" comes up on my radio display and I cannot use any buttons on the radio. Even after I turn off my car it remains there. If I unplugged the interface the radio features come back. Anyone have this problem before? Any suggestions? I searched, didnt find anyone with this problem. Thanks for the help.

 

i got the same problem now.
