I have a 2016.5 Cruze RS Premier with just under 45k miles. everything has worked well until this morning. I left for work hooking my iPhone to the stereo as usual and listening to a podcast. About 5 min into my commute I stopped for fuel. when I started the car back up the screen was black except for the warning screen. no video, no audio, no reverse camera. I shut the car off opened and closed the door and then restarted the car, same issue. drove to work in silence.

After work I went out to the car and the display did not light up as I entered. the radio is black for the most part but will light up randomly. the steering wheel controls would let me o through radio presets and the steering wheelvolume control worked. I let work with the screen black and occasionally showing the warning notice with the ok or language option. about 5 min in to my commute the sound went off and the radio, screen, and radio control buttons on the dash and steering wheel stopped working. another quiet commute.

When I got home I went to back into my driveway and the rear camera showed up on the screen but after a few second got dim. I shifted into park and it went black except for the guide lines. Moving the gear selector from park to reverse the camera would work but be dim and same from drive to reverse.

The dealer wants me to come in so they can recommend a replacement infotainment I am sure but since I am out of bumper to bumper warranty I cannot see spending the money at the dealer to have them drive it in and start shotgunning parts at it on my dime.

I have removed the negative battery terminal and let the car sit for about 30 min now. I tried the onstar reset trick I read about but it has failed to help.I am going to hook the battery back up and hope but maybe someone has a fix.

Thanks in advance. I searched but didn't find anything that was close to my issue.

45 min with the negative terminal unhooked has not solved the problem. Its odd that the radio still holds the presets and I can access them from the steering wheel controls.

Unfortunately it sounds like your radio head unit has died. This has happened to more people than I would think unfortunately. You will need a replacement for it to work again as it is not something that can be repaired from what we've seen on this site. Sorry for the bad news. If you're lucky, you may get GM to help some due to it being a known issue on a lot of these Cruzes.

Thank you for the reply,

I was afraid this was the case. I may have to try to find a salvage unit. My dealer was not willing to help in any way but wanted me to come in so they could charge me to tell me what we already know. I might check other dealers.

Just know if you get one from a salvage yard you'll still need to go to the dealer (or a good independant shop that has the tools) to get it programmed to the car so it actually works.

I know on the Gen1 it can be reprogrammed if your handing and with a <$10 part from eBay. Not sure how it works on the Gen2.

So, I have taken the time to pull the display unit. I am getting constant power and ground from the plug containing red black and a couple grey wires. If I leave the USB plug out the radio doesnt even try to work but with it plugged in I get the same results as has been the norm ( as in OP).

I am concerned if there is a module other than the display that may be bad or if the Blur (in my case) USB cable may be bad.

I am going to call around tomorrow to see what shops may charge to "marry" a replacement to the vehicle. My OEM Chevy parts suppler would not sell me a display unit because the part number comes back flagged as water theft or fire loss replacement. Something about the dealer needs to hook up to some system or another to order the part and the part is on indefinite backorder.

Once I find out the Price to program I will probably pull the trigger on a dismantlement part.

Any other advice from the great people here or anyone done this?

Also, are there any viable aftermarket options?

Thanks!!

It sounds like your HMI(human machine interface) module is bad. This is the "other module" you suspected you have.

Check the 7.5amp fuse34 in the dash fuse block.

The HMI module is mounted vertically with the connectors pointing down, behind the glovebox near the a-pillar. You can try disconnecting it, and reconnecting. If you have access to or feel like buying some GM 12377900 you should treat any connectors you undo and reconnect with it. It's about. $15 and will last a long time, it's great at solving electrical connection issues. I use it every time I disconnect and reconnect a suspected or known problem connection.

HMI module replacement requires the moduoe to be reporgrammed, either by a shop or some vendors who offer the service. Price varies wildy, from $75 up to over $500.

Ive been going thru hell trying to get my radio fixed. Started with the screen going blank and then come back on like it was restarting. Then the bluetooth and the USB/Aux plug ins quit working. Now nothing works. I've been thru 3 donor radios all from 2016.5 Cruzes, all with the same part number. Each time i take it to get unlocked from the dealership i get no they cant unlock it and 3 different reason. This last time they tried to reprogram it and still couldnt get it to work, but still charged me $229. And know im being told that another radio from another cruze will not work at all. And that I'll have to buy a new one for $650-$700 plus a $100 to reprogram it to my car.

This last radio I took apart along with my old radio. I swapped the screens and put the new screen with the old back part and it didnt work (the screen didnt come on). So then I took the old screen with new back part and it come on, MyLink started then the locked screen come on. And my Plugins started working. Thinking this would fix it they still couldnt get unlocked. I had the parts department cross match the VIN# of the donor car and mine and they said it would work, But no it didnt. I hope you have better luck then I did with a salvaged radio. If you go with a brand new one, check around with GM parts dealers online and get the best deal.
These were the cheapest I could find. If I hadn't had to pay that $229 I was gonna have them order me one of these but Im not now.

So I hope you get it working, if you go with a salvaged radio and you get it to work, please let me know how you did it.
