Purchaseda 2012 Scion Xd with a Pioneer Premiun Radio P/N PT546-00121. Trying to get Pandora to play with my Samsung Stratosphere (Galaxy)Smartphone. I can only use the volume control on the radio . No Pandora Icon comes up on the radio screen. I tried finding an App on ToyotaEntunes but no Xd listed. My son tried his Apple Iphone and was able to get Pandora up on the radio screen. Is the Samsung Stratosphere phone not compatible?
