That is the RCDLR antenna (one for the glove box slot is the back up antenna, and it wired directly off the RCDLR in the dash above the radio on the OG/OG-BK wires.
So could be a problem with the connectors/wires from the RCDLR to that antenna, or could be a problem in the RCDLR instead/it not getting any power.
Again, power to the RCDLR from the BCM, and the ground wire from the RCDLR goes to SP208, then the ground wire out of the SP208 goes to the chassis ground on that side of the car.
So a quick check of the RCDLR connector to make sure it getting power, and the ground wire is going to ground would be the first check.
The connector wiring diagrams for the RCDLR, the RCDLR antenna's, and even garage door opener for a C6 2007 car.
