Global Auto Tech
“The XM receiver in my Silverado went bad, so I bought a used one from ebay, when I installed it, it showed "Theftlocked". I found Global Auto Tech after googling how to unlock the receiver, I purchased their service, mailed it to them on a Friday, they received it on Monday and I had it back in my truck and listening to only best tunes on Thursday, less than a week! These folks are legit and freaky fast! Give them your business!”
