GM FIRST USED A DATA LINK RADIO IN 2000 IN MOST CHEVY CARS, THE RADIO LINKS WITH THE VEHICLE COMPUTER, IT HAS 2 FUNCTIONS, THE FIRST IS SECURITY, ONCE THE RADIO LINKS WITH THE COMPUTER IT WILL ONLY WORK WITH THAT VEHICLE, IF YOU TRY TO PUT THAT RADIO IN A DIFFERENT VEHICLE IT WILL BE LOCKED, IF YOU PUT IT ON THE SHELF FOR YEARS, AND PUT IT BACK IN THE SAME VEHICLE IT WILL WORK. THE OTHER FUNCTION IS TO CLEAR CODES AND CHANGE SETTING THE RADIO IS USED TO CHANGE THE SETTING ON HOW YOUR KEYLESS ENTRY OR ALARM SYSTEM WILL WORK, AND USED TO CLEAR WARRING CODES LIKE LOW OIL.

ALL DATA LINK RADIOS MOUNT THE SAME AND HAVE THE SAME PLUGS, BUT THEY ARE NOT INTERCHANGEABLE, YOU HAVE TO HAVE THE PART NUMBER FOR YOUR VEHICLE, MOST WILL CODE DOWN, BUT NOT UP, THIS MEANS THAT A 2002 PART NUMBER, WILL NOT WORK IN A 2003 AND UP, BUT A 2004 PART NUMBER WILL WORK IN A 2000-2004 OF THE SAME MODEL VEHICLE.

MOST DATA LINK RADIOS HAVE TO BE CODED BY A GENERAL MOTORS DEALER, THE EARLY MODEL VEHICLES, 2000-2001 WOULD CODE THEMSELVES THE RADIO CODED TO THE COMPUTER BY JUST PLUGGING IT IN, SOME 2001 AND ALL 2002 AND UP VEHICLES, HAVE TO BE CODED BY THE DEALER USING A TEC 2,
A NEW,USED OR REFURBISHED RADIO IN VEHICLES 2002 AND UP, WILL HAVE TO CODED BY THE DEALER, SOME MAKE WORK AND FLASH CAL ERR EVERY TIME YOU TURN IT ON, BUT YOU WON'T BE ABLE TO CHANGE SETTING OR CLEAR VEHICLE CODES.MOST OF THE TIME THE RADIO WILL BE LOCKED AFTER YOU PLUG IT IN, THE RADIO IS UNLOCKED AFTER ITS CODED.

BEFORE BUYING A DATA LINK RADIO. FIRST CHECK WITH A GM DEALER, AND GET A COST TO CODE A RADIO, THE ONE YOU BUY MAY NOT NEED TO BE CODED.(2000-2001 VEHICLE.) CALL MORE THAT ONE DEALER, THE PRICE VARIES FROM DEALER TO DEALER, IT CAN BE ANY GM DEALER, JUST BECAUSE YOU OWN A CHEVY, YOU DON'T NEED TO HAVE IT DONE BY A CHEVY DEALERSHIP YOU MIGHT GET A BETTER PRICE AT A OLDS, OR BUICK DEALERSHIP.

ALWAYS MAKE SURE THE PART NUMBER OF THE RADIO WILL WORK IN YOUR VEHICLE,

YOU WOULD NOT NEED TO HAVE THE RADIO CODED BY A DEALER, IT WOULD BE PLUG AND PLAY, WE HAVE TO SEND THE RADIO OUT AND WOULD NEED VEHICLE INFORMATION FOUND ON THE STICKER IN THE GLOVE BOX, THE COST IS $65.00 TO HAVE IT DONE, AND THE TURNAROUND TIME IS ABOUT A WEEK.
