So here it is... I pull the dash off and unscrew the Avic D3 installed by Circuit City. When I get to the back of the unit there is nothing plugged into the AV slot...So I go back inside and check the Bypass post to make sure I am not missing something??? Its not my truck so I ask the owner if CC had given him the AV plugs for the back but they did not. Is this normal?? If I get it do I just plug it in and run the bypass as listed on here? Thanks in advance

Hello, I had the D3 installed in my 2007 Chevy by circuit city. The installer hooked up the speed pulse but then disconnected it and he said "the vehicle speed pulse is too fast for the screen to read" I only have a functional understanding of the speed pulse. Any info would be greatly appreciated!
