he bought a Pioneer AVIC Z2 GPS unit and some other components from Circuit City last July for more $3,000 and decided to let their installers do the installation work for him -- apparently after he was told that it'd slide into his Honda Civic without any modifications.The problems then allegedly began when the installer whipped out a heat gun, which was purportedly intended to be used to mold a mounting guide for the GPS unit but instead wound up melting one of the Civic's heating ducts. As if that wasn't enough, the installer apparently also used tape to hold the GPS unit in place, installed the antennae on the inside of the car instead of the outside, and used a glue gun to install the speakers instead of bolting them in place.

that apparently not only resulted in over $12,000 worth of damages but, according to the estimate from a Honda dealership, left the car "unsafe to drive."
