I have a 2006 trailblazer with the single CD. I bought a 6 disc factory cd radio from a 2006 trailblazer for cheap. Anyway, we put it in and I happened to think about the theftlock. The radio worked for a minute but didn't seem nearly as loud as my other radio did. Then it beeped and locked. Before I get my husband to put this back in and I take it and get it programmed at the dealer, do you think it wasn't as loud because it wasn't completely unlocked? I only paid $30 for the radio and don't mind paying more but if it isn't going to be as loud as the other then I'm going to sell it. Thanks.
