I have an 09 with the bluetooth, rearview camera and JBL. To install the OEM GPS system what do I need in addition to the correct MFD and the under seat computer? I'm thinking there is a wiring harness and an antenna. Do you have the part numbers for these pieces? I'm hoping to hit the salvage yards around here since the weather is getting warmer. I'm thinking that I can check on any 2008-09 Toyotas or Lexus cars for the DVD unit. Thanks for all your help. And yes, I know that my Garmin is a better system.
