I have a 2005 Sunfire. I would like to install an aftermarket stereo radio/cd player. Someone told me that all the electronics such as the airbag, security system and computer run through it and that it is very difficult to install. In fact, the old stereo is usually mounted under the seat or in the trunk so it makes the system work. Does anyone know if this is true? Why can't the old stereo be removed and an aftermarket one put in its place?
