Ok, no problem. The letter L means that the unit is locked. To unlock the Doran 360RV you will need to make sure the unit is plugged into the cigarette port. You will need to press and hold the up arrow, down arrow and the P(program) button at the same time. The letter U will show up on the screen indicating that the unit is now unlocked. You will then be able to press your P button to go into your programs to continue with your set up.
