I installed the 2002 Camaro Delco Monsoon am/fm/cd head unit with FABULOUS results. It had the theftlock too which had no bad effects.. Some thought it would not work in a 'non theftlock' car. Well let me tell yas. Its sounds absolutely GREAT! This is without the Volfenhag 800 watt amp that I am gonna install soon.. This is a perfect HU to install in our cars.. Perfect fit too..
