I have an '07 SXT with the factory radio, and I'm ashamed to say I don't know what speaker system is installed. I've been on Crutchfield's website and every time that drop down appears asking about the speaker system, I don't know what to select. :4-dontknow:===============================================FACTORY RADIO BEZEL AND SIZEFor: 2006-2007 Chargers===============================================
In 2006 and 2007 there are two styles of factory head unit.
The "Half moon" style. Where the two knobs on the sides of the radio make it so that the factory bezel has half moon shapes cut into the rectangle opening. This style of factory head unit will not accommodate a double DIN head unit. If you're wanting to put in a Single DIN head unit (common size, non nav, non video deck) then you can use the factory bezel and would only need a Metra 99-6507 to fill the difference between the factory radio and the aftermarket single DIN head unit.
The other style of factory head unit in a 2006-2007 Charger is the factory navigation. It is larger then a single DIN and the bezel that comes in vehicles equipped with the Factory Nav (aka REC Nav) will accommodate an aftermarket Double DIN head unit (double the height of a Single DIN head unit) The opening is rectangular and with the aid of a Metra 99-6510 you can put in either a Single DIN w/ Pocket or a Double DIN head unit.
If you have the half moon style radio and are wanting to put in a double DIN, you need to purchase a factory navigation bezel, widely available at your dealership, wreckers, or even in the B/S/T section of your friendly neighbourhood ChargerZ forum.
Many people have cut up their half moon style bezels to Double DIN but are never satisfied with the end result. Save yourself the time and hassle, and just get the factory navigation bezel. It looks much better and fits better too.
