Hidden Navigation Service Menu

 
Did you know that you can roll down the windows by holding the unlock button?  Did you also know you can roll them up by turning the key in the door to the right and holding in this position.

Did you know you can turn the DSC into Competition Driving Mode.  Press and hold the DSC button for 10 seconds until the light goes out on the dash.  This mode gives you active handling via the brakes but NO throttle managerment when DSC engages.  It is also good for snow/ice operation when you want the tires to spin.

Programming a new Key

Replacing a missing master key is quite expensive from BMW and Land Rover, try not to get sucked into the extra cost of "Dealer coding" You can do this yourself in 2 minutes by following the simple process below.

1) Get in and close all doors. Turn ignition on and off quickly and remove the key (all within about 5 seconds).

2) Within 30 seconds of turning the ignition off, while holding down the "unlock" button, press the "lock" button three times. Release the "unlock" button. (You may or may not get the confirmation from the door locks.)  Holding the key at your head level provides best results as the key sensor is in the side window pillar.

3) Repeat for each key you want to initialize within 30 seconds after the last one you initialized (if you have more).

4) Right after doing the last key, quickly put the key back in the ignition and turn it on/off again to finalize. 

Deativating the interior cabin motion sensor while locking the doors

You can arm the alarm while turning off the interior motion sensor and the tilt sensor simply by hitting the lock button twice within 10 seconds or turning the key in the door twice to the right.

You can monitor the red led on the mirror when locking to be sure you set it in the correct mode.  When you deactivate the interior sensors (with that second push of the key, or second turn of the lock) then the LED goes solid red for 2 seconds before starting to blink.

Using the remote to roll down all windows and open sunroof

You can roll down all the windows and open the sunroof simply by pressing and holding the unlock key.  In Europe you can use the lock key to roll the windwos up.  It is possible to set the BMW or Rover key programming to roll the windows up as well, but it would require a "smart dealer" to program.  And we all know how many of those their are.
