I currently have a 900bt in my 2004 toyota tundra that I installed several years ago with the help of this forum.  I would like to upgrade to a AVIC-8200NEX.  My question is the wiring connections and plugs compatible between the two or is it a start over install??  Thanks in advance for replies/help

if you used the ISO connector that should be no problem

Thank you, I was hoping that was the answer
