The USB port on the back is USB mini. If you want to adapt it to standard USB female so you can plug in a USB thumb drive, we offer a couple optional cables to accomplish this. The cheapest option is few inches long and will hang out from behind the radio. Or, choose the surface mount kit instead. It allows you to mount it in the glove-box, console, dash, etc. You just have to drill the hole. It is approximately 3/4" in diameter and the cable is 6 feet long, which allows for a multitude of mounting options. Both options appear in a drop-down list towards the bottom of this ad.

As noted above, there are no returns accepted on this item. Why? Because, once it's connected to your wiring harness, it will pick up your VIN. That means it will automatically lock if it's put in any other vehicle, since the VIN doesn't match. (It doesn't lock like this for you because there's no VIN in memory when it's new.) For example, let's say you install this and it doesn't solve your problem with sound output on some of your speakers. (A common report on these vehicles and replacing the radio almost never solves it.) Now it has your VIN in memory and probably also has mounting marks from the screws you used to installed it. If you were to return it, we'd be sitting on a radio that used to be new but clearly could no longer be sold as such. We sell radios like that (new take-outs) for significantly less money because the customer is now required to pay a dealer for programming to get it to do anything in their vehicle. This is why returns are not accepted. We have no desire to get in a messy situation where we have to withhold an unknown portion of your refund to account for all changes in condition. It's easier just to say returns are not accepted. No, we do not make exceptions to this policy either. Unfortunately it's just the way it is. Please understand that we are not GM or Delco and we aren't affiliated with them in any way. (One of the reasons our prices are so much cheaper.) We have no liability or responsibility for the functionality of your audio system. While we feel bad for your predicament, we cannot be put in a situation where we are obligated to accept a return for something that has changed in value. If you're having problems and this radio doesn't solve it, it's between you and your dealer to figure out a solution. If they were the ones who told you to get a radio, perhaps they will buy the radio from you...


Our research shows this radio works in the following vehicles. However, we have provided the part number. It is up to YOU to check with your dealer to determine if it will work for your application. Returns are NOT accepted, as indicated in great detail in the ADDITIONAL INFO section of this ad.

Returns are not accepted once this has been connected or mounted. As soon as it has been connected, it picks up your VIN and can no longer be sold as new. As soon as it has been mounted it will be obvious it isn't new as well. Make sure this is the part you need before ordering.

This radio, like all the new GM radios, is designed to work in conjunction with your car's computer. Consequently, you may need your dealer to program the computer once it is installed in your car in order to get 100% functionality. Since it has never been used, it will usually have some degree of functionality without the programming but you should plan on having it performed to ensure 100% functionality.

The mini USB port on the back can be adapted to a standard USB connection using one of the optional cables offered below.

I purchased a GM radio #20935459. It worked perfectly without a visit to my GM dealer to unlock it. The GM dealers in my area charge $150 to unlock a radio. I was very happy to be able to purchase a new radio that had never been installed.
