Anyone know how you enter the code? The card with the code on it says to enter it using the presets. But there is no presets on my navigation controls and i can't bring up the audio screen.

After you enter the NAVI code, enter the radio code using the TUNE knob. Watch the LCD screen at the top of the dashboard for this step. Spin the TUNE knob to dial the number, push it in and go to the next number in the code until all four digits are entered.
