Hello, I've heard that it's possible to purchase the Toyota (made by Pioneer) XM Radio Kit (Toyota Part # PT546-06040) for the Solara and simply plug it in to the back of the 2004 Landcruiser's factory radio and that the XM Satellite radio will work thru the audio system and will be displayed on the Navigation system display. Does anyone know if this is correct? Thanks! A proud new owner of an '04 Landcruiser
