2011 Acura RL Owner's Manual - Page 305

Compass System (U.S. model without navigation system) When you purchased the vehicle, you should have received two cards that have the audio and compass system's security codes and serial numbers. Keep these cards in a safe place in case you need the codes. If you lose the cards, you must obtain the security codes from your dealer. Enter the four-digit compass system security code. If you have entered it correctly, the display changes to the Disclaimer screen. You have ten chances to enter the correct code. If all ten are incorrect, turn the ignition switch to the LOCK (0) position, then back to the ON (II) position to have ten more chances to enter the correct code. To enter the code, turn the interface knob to select the number, then press ENTER to select it. Keep doing the same procedure to enter all four correct numbers. If you need to delete the number you entered mistakenly, move the interface selector to the right. Follow the instructions in the audio system section to enter the 5-digit audio code (see page 280 ). The system voice will not operate if the audio code is not entered. GPS initialization Features Depending on the length of time the battery was disconnected, your system may require GPS initialization. If it does, the above screen appears. Follow the instructions on the screen. CONTINUED 299
