This adapter is exactly what I needed to keep my OnStar on my 2006 Chevy Active. Easy to connect and it works great. Sonic Rocks.

Customer Testimonial

Absolutely Fantastic!! Everyone I spoke with was very polite and personable. The stereo I purchased is of top notch quality and has worked perfect since day one. I will soon be back to purchase a Sub and speakers. I suggested this website and it's awesome deals to my friends. Keep up the great work.
