So i bought this stereo for my work van on ebay cuz it didn't come with one . I got it in the mail yesterday and installed it this morning...turns out i need the lock code. The guy i bought it from said i can return it, but i'd rather not cuz it was cheap as hell and driving sucks without a radio. Now i called the chevy dealer and they wanna charge me $93 just to unlock the radio with their magical scanner. If anyone works at a chevy dealer or has access to the tech 2 scan tool PM me ASAP! Oh yeah, it's a 2006 Chevy Express 3500.[/align]
