FIRST OF ALL I WANT TO THANK ALL OF THE MEMBERS IN HELPING ME BUY AND DECIDE WHAT UNIT TO BUY. I HAVE A 2008 TAHOE AND INSTALLED THE Z2 (AUGUST 07) IT WAS PREATTY EASY TO DO THE 2 WIRE INSTALLATION. I JUST HAVE ONE QUESTION. I DID THE 2 WIRE BYPASS AND EVERYTIME I CHANGE THE INPUT TO EITHER NAVIGATION OR DVD THERE IS A SCRREN I HAVE TO PRESS OK. DID I DO THE 2 WIRE BYPASS CORRECTLY? ONE MORE THING IF ANYONE IS HAVING TROUBLE MAKING THE FACTORY BACK SCREEN TO WORK HERE IS THE LINK IT TOOK ME ABOUT 20 MINUTES AND I PURCHASD THE RCAS PRE CUT FROM RADIO SHACK. HOPE THIS HELPS SOMEONE.
