terry993 Posted November 11, 2006 Share Posted November 11, 2006 I have a 2007 IS 350 that is going in to Lexus service Monday for installation of the Lexus OEM XM Sat Radio. Should they use the existing shark fin antenna, or will they have to put another antenna on the trunk and wire through to the Nav/radio in the dash?
