Depends if you go aftermarket or OEM. I went aftermarket and am pleased with the results, cost me $167 Cdn and 20 minutes to install. Most of the time was spent disconnecting and reconnecting the battery and reading the instructions.
Every minute spent angry is a happy minute lost for ever and ever!!!

Never drive faster than your guardian angel can fly
I chose to go factory
First since the brains for cruise control is built in to all Cobalts.
Second is on the cruise control buttons.... I like the look of factory install controls.
Finaly for me at least, I wanted a leather steering wheel and not an aftermarket coozie wrap.
Either way one MUST get the body control module (BCM) programed to enable cruise.
