I am trying to install an XM receiver in a 2002 camry Le using a PIE adaptor to convert the 12 pin outlet in the back of the radio to an Aux port. I have the am-fm cassette and cd radio without the cd changer. Has anyone tried using this adaptor to successfully convert this port to an AUX port to which I can connect my XM receiver to work thru the radio without having to resort to an FM-modulaator setup.
