Circuit City caused $12,119 worth of damage to VTECnical's 2007 Honda Civic while trying to install a Pioneer AVIC Z2 navigation system. Honda later declared VTECnical's car a fire hazard and told him it was unsafe to drive. Despite destroying the car's heater ducts, stock wiring harness, and dashboard, Circuit City has refunded only $3,190, and insists that VTECnical speak exclusively to their third-party insurer. Hit the jump for Honda's damning condemnation of Circuit City's shoddy workmanship and a video of the damage.

The full repair bill is posted on 8thCivic's forums.
