Posted: February 2nd, 2013, 2:53 pmCouldn't have been easier! Scoped out the On-star unit location before ordering so I knew where to go once the unit arrived. It is easily accessible behind the glove box - no need to remove the dash and no tools required. Slipped off the two connectors from On-star, slid them on the Blue-star unit, paired the phone (iphone 5) and made my first call within 5 minutes. Slid the unit under the dash next to the existing pieces. I've adjusted the phone volume and still figuring out the finer details and so far I'm very impressed!
