So i bought my 04 tl literally hours ago from a used dealer. And of course of excitement i started messing with it! So when i bought the car the navigation screen was locked (needed code) dealer said theyd get it tomorrow. Well i was messing with the radio pressing buttons and next thing you know theres no Radio station showing on the very top screen? Where the climate/radio/clock show...radio works fine i can gear the stations but i cant see what station it is and what not....any advice??? Im kinda freaking out since i bought the car literally 4 hours ago!
