you do not have a number 9 in the radio code. the radio code was on a small white sticker and there was 3 copies of it when the auto was shipped to the dealer. If you have a navi system in the car that may be the navi code that you are looking at. If you cannot find your radio code you will have to contact your dealer and he will want the serial # for the radio. Turn the radio off and press and hold the #1 and 6 buttons. Now press the power button. You have entered the self diagnosis of the radio. press the #2 button and it will give you the serial #. Press it again and you can temp. listen to your radio. The radio will fail after 3 attempts. Pull the neg. cable off the battery and start over.
you need the serial number from the radio unit and the navi system (not the screen). If you are the origal owner, that was given to you with the books. the radio code is a 5 digit number and the navi code is a 4 digit number.they may have put a sticker with a 5 digit number on the inside walls of the glove box. if there is a sticker with more that 5 numbers, call you dealer with that number, that may be your serial number. the navi system has 4 digit code
The wire under the hazard button has probably come loose. Most GMC vehicles this year range were made with a closed circuit wiring between the flashers, hazard lights, and rear defrost. Over time the wiring under the hazard button has been known to loosen. This causes the whole system to lose function. If pop out the hazard button on you center console you should be able to tighten that wire back on and the system should work again. The same thing happened to me when I put in a new radio. I bumped the wires off and my blinkers, rear defrost, and hazard lights went out. I replaced the fuses and the flasher relay but nothing. Then I asked a mechanic and he told me what I just told you. Hope it helps!
The analog clock has little buttons on the face to move the time forward or back. If your FX has NAVI hit the setting button then choose CLOCK. If it doesn't have NAVI hit the menu button and scroll down to the clock setting.
