Thank you!!!! Last week my Equinox's battery shorted out caused a huge huge huge snowball effected first triggered my passlock to shut off my fuel and a few other things. Once I sorted ALL that out.... next I found my stereo locked. Tried everything under the moon to break it. Found this forum and not even a minuet with the SD in the headunit I was able to start using my radio again. THANK YOU!!! Not everyone who is a noob is a thief. Sometimes you're just a single mom who got something really cool as a gift and have something bad happen. Thank you to the OP for posting this!!!
