G'Day, Just purchased a 2004 RX330 and it doesn't have the tonneau cover. Questions: 1- with a black leather interior but grey cloth roof what colour is the tonneau cover supposed to be? 2- Does anyone have repair service manuals for this vehicle? cost? 3- Is there a manual that tells how to do the programming/reset programming of the electronics?...for instance, my L rear window does not operate from the driver's control switches but it works from it's own switch. cost?
