No pictures just yet. I picked up a unit on ebay, gave $85 shipped to my door. It was listed as not working because it came form an electronics recycle house, listed as not working, because they didn't have the equipment to check it out. Unit arrived today. I'm under the assumption that all of the nav units are the same size...Tear into the dash, get my unit out. Hook up the nav unit, fingers crossed. We have power! Bow Tie comes up, then a black screen. Could be because I need the unit unlocked, we will see. Try to slide the unit into the factory slot no luck. The mounting brackets are different so it wont slide back into the dash all of the way. I rest it in the hole, try and work the trim into place to see if its going to clear. The unit is too big. So what I'm wondering is. Does anyone know if there are different size units out there? I'm going to pull the trim off, hook the stereo up and go to the Chevy dealer tomorrow morning and see if they can hook it up to a tech II and see if I can get it working.
