Hi all: I just got a 2009 RX350 without nav, non-ML audio system. I am looking to install the Pioneer Avic X930BT as well as a backup camera. Here are the components I'm looking at getting: Headunit: Pioneer Avic-X930BT Ipod Controls: Pioneer CDIU-203V Ipod audio/video cable. Steering Wheel Controls: PAC SWI-PS Backup Camera: Boyo vtl425 ultra slim Trim/Harness I'm undecided on this. There are 2 options: 1) Beatsonic SLA-82A if I want to do plug and play, retain use of the factory amp. 2) JDM Toyota Harrier double din trim piece + Metra 70-8113 Toyota harness if I want to do factory amp bypass and use the aftermarket HU's internal amp. Questions: 1) Silly question, but does the install of any aftermarket radio violate any warranty (mine is a certified pre-owned)? 2) Does anyone have any opinion about the two choices of using the factory amp vs doing an amp bypass? I have heard complaints about noise/hissing using the factory amp with an aftermarket head unit. I could save a good bit of money doing the amp bypass myself, and probably better audio quality. 3) If do an amp bypass, why would I need a separate metra harness? I have read on the forums that this harness is required. 4) Does anyone have a link to the wiring diagram for the the amp/speakers for this car? 5) Is the factory amp located behind the rear seats? 6) Am I missing anything? Any other components necessary? Thanks in advance!
