Rare to see such honesty today! We bought their pro module for our 2000 LeSabre, even tried to install it with the instruction for the 99, until we discovered the 2000 is not supported by newrockies. Our fault 100%, it was all written on their website. We were over 40 days, contacted them and they accepted the return anyway! Refunded in full. I love these guys! This is better than the best! I would have never hoped to get my money back for something that was my fault and after the return deadline. I'm telling everybody!
