Hey all just wanted to find out if anyone had replaced their factory stereo? I am looking to put in a pioneer x910bt into the outlook we just bought. Any tips? I am pretty sure I have all of the connectors ordered that I will need to keep the steering wheel controls and onstar. If anyone has done this in an 09 and had any issues or things to avoid let me know otherwise I will post how it goes and if everything works when I am done.
