I am installing a Sony XAV-AX5000 in my 2002 TrailBlazer LS. This vehicle has the base stereo system and no OnStar. Here are my concerns:
  • Will the Scosche ICGM8BN installation kit work with this head unit and vehicle?
  • Where can I get constant and switched power?
  • How do I retain the chimes and RAP?
  • What is the additional black connector on the factory stereo?
  • Do I need to make any connections for the security system?
  • Are any modifications needed in order to fit the new head unit?
My goal is to complete this installation with only minimal modifications. I would appreciate any documentation on the installation process, particularly wiring. Looking forward to your advice.
