Called stealer and what do you know there's no button/knob available, - the whole thing needs to be exchanged as a unit. Any suggestions of a do it yourself fix? All I would need is ...

I have a 2005 SLE and the horns sound like old people's car horns. I checked them and they both work. Was just wondering if there's another set of horns out there that is louder and better sounding. I do want to stay with a direct bolt on, maybe GM application without having to mod or drilling holes ...

Decided to add a CD changer to my '05 Bonneville. Could use some help with what all do I need. I'm looking for part number (stock GM unit for 2005) of the actual changer, pictures and anything that would help to do the whole job. thx!

Dang! Got up this morning and discovered a crack in my windshield! I have a '05 SLE with 40k on it, never hit anything, no hail, nothing! It's a real weird crack.
