NOWADAYS, A REAR VIEW CAMERA IS AN IMPORTANT PART OF VEHICLE SAFETY AND LEGISLATION IS PROPOSED TO MAKE IT MANDATORY ON MANY LARGER VEHICLES. IF YOUR CAR DOES NOT HAVE A FACTORY REAR VIEW CAMERA, MANY OF THE NEW 2007-08 GM NAVIGATION RADIOS CAN BE UPDATED FOR REAR VIEW CAMERA CAPABILITIES WITH A SIMPLE SOFTWARE CHANGE FROM YOUR DEALER. THIS PROCEDURE IS DOCUMENTED IN THE FOLLOWING DOWNLOAD AND CAN BE USED AS A GUIDE FOR OTHER VEHICLES.
       CLICK TO DOWNLOAD: FACTORY PROGRAMMING PROCEDURE EXAMPLE
              CHECK WITH YOUR DEALER FOR CAMERA PROGRAMMING AVAILABILITY FOR YOUR RADIO

   AFTER PROGRAMMING, THE SCREEN VIEW WILL AUTOMATICALLY SWITCH TO AN EXTERNAL VIDEO INPUT WHILE THE VEHICLE IS IN REVERSE. THE CONNECTION FOR THIS VIDEO IS PROVIDED IN THE LOCKPICK 4 AND GMX-320 HARNESS AND MAY BE USED FOR A AFTERMARKET REAR VIEW CAMERA IF DESIRED OR FOR ANOTHER VIDEO INPUT. THE LOCKPICKS CAN TURN THIS VIEW BACK ON WITH SIMPLE STEERING WHEEL BUTTON PRESSES IF DESIRED AT ANY TIME, EVEN WHILE IN DRIVE IF NECESSARY.
    WITH A SIMPLE SWITCH SETTING ON THE LOCKPICK MODULE, THE LOCKPICKS CAN ALSO ALLOW STOP THE SCREEN FROM BLANKING IN REVERSE IF A REAR VIEW CAMERA IS NOT TO BE CONNECTED AND THE VIDEO INPUT IS TO BE USED FOR OTHER NEEDS.

*NOTE: IF YOUR RADIO IS NOT EQUIPPED WITH DVD OR VIDEO AUX INPUT CAPABILITY, THIS PROCEDURE CAN ALLOW YOU A MEANS OF INPUTTING VIDEO/AUDIO TO YOUR SCREEN AND USING THE LOCKPICK TO CONTROL IT. A FACTORY CAMERA OR THE PROGRAMMING ENABLED IS NECESSARY TO USE THE FULL MULTIMEDIA INPUTS OF THE GMX-320

**THE GMX-320 LOCKPICK CAN TURN ON THE FACTORY INSTALLED  REAR VIEW CAMERA OR AN AFTERMARKET REAR VIEW CAMERA AND DISPLAY IT ON THE FRONT SCREEN AUTOMATICALLY WHEN THE CAR IS PLACED IN REVERSE, OR AT ANY TIME WHEN IN PARK OR DRIVE (EVEN IN MOTION)
 

***THE GEN 4 LOCKPICK CANNOT TURN THE FACTORY CAMERA ON AT TIMES OTHER THAN REVERSE, BUT IT CAN ALLOW AN AFTERMARKET CAMERA OR VIDEO SOURCE TO BE PLUGGED INTO THE LOCKPICK HARNESS AND CONTROLLED.

****IF YOU ACTIVATE THE CAMERA INPUT WITH NOTHING CONNECTED TO SHOW A PICTURE, SOME RADIOS WILL DISPLAY A MESSAGE SAYING THERE IS NO PICTURE WHILE THE CAR IS IN REVERSE. THIS MESSAGE ONLY SHOWS WHEN THE SCREEN IS BLANK AND THE SCREEN IS WAITING FOR THE PICTURE FROM YOUR CAMERA OR VIDEO SOURCE - JUST PLUG SOMETHING INTO IT WITH A PICTURE AND IT GOES AWAY. I KNOW IT SOUNDS SIMPLE, BUT SOMEONE WILL ASK : )
