Since I'm relpacing the malfunctioning Bose head unit in my 06 Escalade, I will also be removing the 6cd changer. I plan to convert the opening where the cd player is now mounted into a phone charging cubby hole. So I'm looking for a charging pad that will fit the 7" wide opening and can charge two phones at once. Has anyone done this? Any suggestons where I might find a 2 phone charger pad that will fit?
