If you haven't had a chance to install a double din in-dash stereo into a 2003-2007 Chevy Silverado, then you may find this tip helpful.
If you try to fit the stereo into the dash cavity as is, you will notice it will not fit correctly.
Due to the form of the plastic dash supports the stereo will not go far enough back to allow for proper mounting, unless you remove some of these pieces.
Don't worry, you won't need anything more than a pair of angled pliers. I've seen other installers use different methodes, but I think this is the easiest way.
I normally begin by removing the two corner pieces, the plastic is quite brittle so you won't need much force. Be carful the broken edges will be very sharp.
After I remove the corner pieces, I then remove the center suport.
Once the removal of the interfering plastic is complete, I normally do on last thing...
That is cover the rough edge with some duct tape, to avoid possible damage to any of the wiring and or your hand when managing any of the wiring when mounting the stereo.
