How-To: Disassemble Radio To Program VIN

83990 Views 97 Replies 30 Participants Last post by  Blasirl
I have had some people ask me about reprogramming the VIN number in the radio, so I thought I would write a how to guide that explains how to disassemble the radio so that the chip can be reprogrammed.

For more information on upgrading to My Link, see this thread.

Here is a thread on how I created the My Link wire harness to upgrade from the green screen
http://www.cruzetalk.com/forum/36-gen1-audio-electronics/196994-how-i-did-mylink-wire-harness.html

This is for the standard My Link radio. The navigation radio that is used in the Cruze is similar, but you will notice a couple minor differences.

NOTE: The electronics inside the radio are sensitive to static electricity. If you decide to do this project, it is important to take some precautions to avoid frying the electronics. It’s actually very simple, and here are a few helpful hints that should be good enough.
- Don’t wear wool or other materials that attract static electricity.
- Avoid rubbing yourself against the carpet flooring or fabric/nylon chairs while working on the radio.
- Work on a hard solid surface (i.e. not on the carpet floor or your bed)
- - When handling the PC boards, hold them by their edges and try not to touch any of the contacts or components on the boards.
- Ground yourself by touching something that is connected to a ground, such as the bare metal side of your desktop computer case while it is plugged into the wall but turned off. Re-ground yourself every time you move away from your desk and before each time that you touch any of the PC boards. If you are concerned, you can also purchase an anti-static wrist strap online that is designed to keep you grounded.
- Don’t set the PC boards down on anything that can conduct static, such as fabric, carpet or plastic.

Do this project at your own risk. There is always risk anytime you disassemble modern electronics, and I am not responsible for any damage caused by taking apart the radio.

Tools needed to dismantle radio:
- Small Phillips Screwdriver.
- Regular Phillips Screwdriver.
- Regular flat blade screw driver.

I will be referring to the sides of the radio. The top is the side that has the sticker label. The front is the side with the CD slot. The left side is the side with the heat sink and fan.

1- Start by removing the two black screws below the CD slot. These screws hold the front of the CD mechanism in place. You will need a smaller Phillips screwdriver to remove these.

2- Remove the 7 silver screws around the outside of the front panel. There are three on the right side, two on the top, and two on the left side. See photo below:

3- Remove the heat sink with the fan on the left side. To do this, first remove the 4 black screws. Then, remove the 2 silver screws in the middle of the heat sink. Then remove the silver screws next to the fan. After removing the screws, the heat sink will come off. If you carefully reach inside, you can unclip the fan plug from the PC board. Just pull up gently and it will unplug. Set the heat sink and fan aside. Do not remove the white grease that you see on the heat sink or the amplifier chip. This is necessary to properly transfer the heat. If you want, you can re-smear the grease around a little so that the chip makes good contact with the heat sink.

4- Remove the front panel. To do this, put a flat blade screwdriver into the slots at the top of the radio between the front panel and the top panel . Then carefully pry the front panel forward about a quarter inch. Then, look for a small square hole on each side of the front panel. You will notice that there is a small tab inside (see the first photo above for location of the tabs). Slide the flat blade screw driver behind the front panel to unlock these tabs. Do this on both sides and the front panel will slide off.

Be careful when removing the front panel because there are some wires attached to it. One wire goes to the Bluetooth antenna on the front. The other is the CD control cable that is glued to the front panel. Carefully peel the CD ribbon cable from the front panel. The Bluetooth antenna wire will be removed in a few minutes. Lay down the front panel so that there is no tension on the wire to the Bluetooth antenna.

5- Next, separate the radio into two halves – top and bottom. To do this, remove 1 screw from the center of the right side. Then, remove the two screws on the back. Carefully lift up the top half of the radio and turn it so that you can see the Bluetooth antenna connector on the PC board.

6- Remove the Bluetooth antenna wire and the CD control cable. You will see where the Bluetooth antenna wire connects to the PC board. Use your fingernails and carefully lift up on the connector. The gold-plated connector will pop off. Then, slide the CD control cable out of its connector on the PC board. Just gently pull the cable out of the connector on the PC board. Set the front panel and the bottom half of the radio (with the CD mechanism) to the side.

7- Remove the top PC board. Unscrew 4 screws that hold the top PC board in place. Two are toward the rear of the board. The other two are on the metal bracket at the front of the board. One connects the metal bracket to the bottom PC board. The other is on the outside of the case. Holding the edges of the board, gently pull up. The top board will unplug from the bottom board. Set the top board aside. Remember to hold the PC board by the edges and place it in a static safe area. See photo below:

8- Remove the XM Radio. The XM radio is a small aluminum box on the side panel. To remove it, first, remove the ribbon cable from the PC board. To do this, carefully lift up on the sides of the connector. This will unlock the cable. Then, gently pull the cable out. Then unscrew 2 screws on the outside of the radio that hold the XM radio in place

9- Remove the bottom board from the case. Unscrew 5 screws that hold the bottom board to the chassis. One is on the back of the chassis by the antenna connector. Carefully lift it out by the edges of the board and turn it over to see the chip that needs to be programmed. (See image in step 8 above for location of screws)

10. Program the chip

11. Reassemble the radio by doing everything above in reverse. When you place the top PC board back over the bottom board, make sure the connector between the two boards snaps back in place. You may need to gently press down on the board above the connector to get it to snap in place. Don’t push too hard so that you don’t break anything. When you get to the XM radio ribbon cable, slide the cable back into the connector and then push the locking bar back down. For the Bluetooth antenna, put the connector in place and gently push it down until it snaps on. For the CD ribbon cable, just slide it back into the connector. Make sure the ribbon cables go back into the connectors the same way you took them out so that they make connection.

Sorry to reply to an old post, but wanted to thank everyone involved for all the great information. I had to replace a defective mylink radio in my 2017 chevy equinox, and the dealer spent 3 hours trying, but could not get the VIN number changed.

Using the info from this post (and a couple others here on CruzeTalk.com, I was able change the vin in the EEPROM and everything is working great.

Thanks again for such a great resource.

Good to know that at least the 2016 and 2017 silver boxes are similar if not the same to Gen I boxes.

Yeah, everything seemed identical. My eeprom chip was made by a different company (mine was a 24128RT made by ST), but it worked the exact same. In fact the programmer didn't have my chip listed, so I selected the ISSI 24C128 chip as shown here and it worked fine.

Also happy to note that I didn't need to do anything to allow it to program (didn't have to lift pin 7, or remove the resistor). I saw some comments in other threads that the newer nav radios you didn't have to mess with the write-protect stuff.

This worked like a charm on a 2009 Cruze, EU version, no NAVI, just the simple one line blue screen.

Thanks alot!

Hi All

I have got all the bits together to reprogram my eeprom to update my VIN, however someone on one of the UK forums says that you must also change two bytes just after the VIN and just before the Pana chr$ he has actioned this for me and sent me the bin file back to burn, I would like to know what this is about

Can anyone advise

Thnx

I remember a post where they had issues after connecting an amp and am pretty sure there was an eventual resolution. I do not have the time at the moment to look for it, but I would look through the Gen I Gen1 Audio & Electronics sub forum.

Does your car have premium sound? If so, there's a amp in the trunk that may need to turn on if you're still using the stock setup.

Wow, this thread has been so helpful. I am very very new to auto audio, so thanks for this. My ‘12 Cruze with MyLink is stuck in that reboot loop. Strangely enough, the MyLink screen will stay on the default Chevy screen, and the radio is technically active (my phone connects via Bluetooth and I have blinker sounds and everything), but as soon as I call for anything, like if I turn the radio on or if someone calls me, the speakers will play sound for a quick second, and then the whole system crashes and begins the reboot loop cycle.
We did the negative ground and everything. I even replaced just the control panel and screen which was paid for by the dealer I bought it from. I was pretty sure the receiver needed to be replaced as well, but he didn’t want to go that route. I am fairly sure the receiver needs to be replaced. Sound right to you guys? If so, I have a couple of questions that I feel like go well with this post:
1.) Is there no way to take my receiver apart and repair it? This is the closest I have found yet to anyone taking their receiver apart and doing any work on the internals.
2.) If I do have to replace the receiver, I’ll need one compatible with the Pioneer system and MyLink. I would also like the flexibility to add a stock backup camera in the future. Do I need to search for something specifically to get a backup camera capable device, or are MyLink units backup camera capable by nature?
3.) Does the process for reprogramming the VIN to unlock the radio detailed in this post work for a 2012? Thanks again all!

Hi all. I have a 2014 Cruze Diesel with the Color MyLink/non Nav. I bought a used Nav MyLink and button panel from a recked 2014 Cruze Diesel and programmed my VIN into it. When I put the radio into my car I get sound, I can change sources and I get XM. But the display isn't coming on. Any ideas? I put my old unit back in and everything works like before.
Thanks in advance and thanks for the great information compiled here.

Has anyone done this on a UEW radio? It's a 2012 Navigation, MyLink radio. Which chip is the VIN chip, and which chip do I need to select in the EEPROM program? Not able to get the VIN to pop up in the program. Thanks!

Update: I tried every 24 series chip I could find on the board. I could not get any of them to read properly and certainly could not find a VIN string. Admittedly, I am a newbie, but at this point, I'm just going to drop the money to have a third party (not local chevy dealership) unlock the radio for me. It's a big bummer; I love to DIY things, and this seemed like a good chance to learn a new skill, but the layout of the UEW radio is so different than those shown here, and the part numbers on the chips on my PCB do not match any of the part numbers in the programming software, so it was impossible to determine which chip I was actually looking for and then which chip to select on the software. Ah well - win some/lose some.

Thank you so much for sharing your knowledge. I adapted this to my 2012 Chevy Sonic LT. After removing the satellite radio module, i was able to access the chip and change all the vin values to "00" in the left pane. I plugged it into the car and full operation. I had the mid-level radio installed from factory. Thank you again, saved $95 to have someone else do it. I ordered the programmer from Amazon:
