Just manually updated the CP2A to 8.22 and they have not fixed the blank screen bug yet. No issues found in the 5 min I tested it.
 
Diehminer, I caught a quick glimpse of an error code this morning before I got the blank screen. It was Error-02-62, which is iPod communication error.

As of fw 2020-08-22 neither my CP2A or Carlinkit USB-C see my climate controls or gear shifter as function selectors for my Pioneer headunit.

It also brought back the constant track change workaround of plugging 1 unit into another.

Does not enable placing or ending phone calls still.

Can also confirm 8.22 seems to fix the GM issue for me. I almost don't ever want to update again now that the audio glitch and this are fixed.
 
Can also confirm, that 8.22 works with Mercedes C Class 2019 as well. 8.20 didn't start and I had to go back for 8.4.
Very fast startup now!
 
Any non GM owners with a working almost fine unit try 8.22? Any noticeable improvements? Glad the GM fix is in, but my guess is this firmware is a purposely designed slow boot. 30 seconds is a long time.

Updated to 08.22. I have not had any appreciable improvement. The device boot in my case is the same.
 
Hey man, here's the email they sent me. Let me know if you have any issues downloading it. I backed up the file on my OneDrive as well.. :)

Code:
"Hello there,
This is the version of the firmware upgrade, you can try.
Please enter the link to download the unzipped folder and unzip the file "U2W_Update.img"
https://drive.google.com/file/d/1vTRrNbOK2D8-mJ4YXgfF5VoBJWHPAqov/view?usp=sharing

This upgrade method is different from the past, you need to pay attention to 100% follow our upgrade steps, otherwise the dongle will die.
Please refer to the attached picture.
About upgrading the dongle/power adapter to upgrade the dongle:
●Preparation materials: product dongle, power adapter, USB flash memory
●Method:
1. Please save the Auto_Box_Update.img file on a USB flash drive
(The format must be FAT32/allocation unit size 1024bit or the default value) root directory, and insert it into the USB port of the product.
2. Insert the product into the USB charger (please do not use the USB port of the car and the computer!!!)
3. Wait 2-3 minutes until the red and blue LEDs light up at the same time. Unplug the USB flash drive.
4. When upgrading the product, do not turn off the power or remove the dongle.
●For details, please refer to the attached picture.
After a successful upgrade, you can return to the car for testing.
Looking forward to your reply,
best wishes. "


To clarify, here's what my problem was with the device:
Mine wasn't completely dead. The lights would be on, "red", and it would broadcast a WiFi SSID "AutoBox-582f" (if you see it, you can connect with the Password 12345678). My problem was, the USB-C to USB-A connection didn't provide whatever the car's need to detect CarPlay, and my phone would no longer connect via Wireless CarPlay. Basically, a brick.

The update they had me do, that resolved it was an updated firmware file and then you connect the USB-C to USB-A cable to a power supply (not the stereo, I just used an iPhone 5w charger). Format a USB drive as FAT32, and place the IMG file on the USB drive. Plug in the device, let it power up (usually 30 seconds or so, until the light is red, and I saw the WiFi SSID), and then connect the flash drive. It flashed red/green a few times after connected, and then rebooted. I gave it another 5 minutes (just to be safe) before pulling the power adapter and testing on my stereo. Resolved the issue, and my stereo started to detect the device/CarPlay again.


Let me know if you have any questions.


@Sam Abbott

Thanks for posting the link and the clarification.
The fw did not work as my Carlinkit U2W with the USB A plug is bricked which has only the blue led lit up when plugged in.

Anyways, here's a short backgrounder on how I managed to brick my device - not that anybody is interested to know.

So my USB Type A Carlinkit which I bought thru eBay last Jannuary was working fine without any issues that were being reported here in this thread, no 5min or so audio glitching, no black screen, no out of the blue disconnection. It just worked out of the box. And because of this, I never had the urge to update the darn thing.

Anyways, fast forward to July 24, 2020, I was browsing around Lazada (its an online shop here in SE Asia similar to Amazon and eBay), and lo and behold, there are lots of ads for Carlinkit U2W Type C version and were priced at around US$90.35 with free shipping. So I thought this is a good opportunity to "upgrade" to the USB C version which is having good reviews from here in this forum particularly the "faster" bootUp and connection, etc etc...

So... I paid US$80 for the dongle [used a discount code]. Ordered July 24th and received the package July 31.That was fast considering the COVID19 situation down here and the dongle coming in from CN.

Tested the new USB C dongle on my GM vehicle, seemed better as was described by the experience of other members here. Checked if there was an update, and there indeed was an available update [7-17] but I din't update as the dongle is working flawlessly.

Two weeks ago, I decided to update the USB A version, checked for an update, it said something like 6-17 was available, clicked update, got stuck at 90% for a couple of seconds until it finally rebooted. After carplay came back on, I checked for an update again and it said 8-10 was available, clicked update, Update Success message, it rebooted, and then nothing!!!!

And that folks, is how I managed to brick my USB A dongle.

This forum has the most comprehensive discussion regarding these carplay dongles, and right now, I'm just waiting for a post that would, or could, somehow resurrect a bricked dongle. LoL

BTW, that USB A dongle had fw 2019.12.19 on it before It got messed up.

Anyone able to upload a copy of 08.22 please? Downloading from their servers for me says it will take 2 hours!

Interesting. I haven’t seen any iPod error messages. Are you getting the blank screen on every start up like me?

Pioneer HUs treat the CP2A and Carlinkit units as iPods/iPhones and will even allow you to use them as such from the iPod source in addition to CarPlay mode. I don't know if other aftermarket or OEM headunits do that also.

Yes, I am. Even with your workaround of pairing the HU to my phone using bluetooth, it would still happen occasionally. I only managed to get a "split-second" glimpse of the error code and that was only because I was intentionally watching my display. It's been a long time since I've seen that error, I used to get it a lot when using the iPod source when I first bought my HU in April 2019 but it went away after a particular iOS 12 update was released (I don't remember which one).

So uhm, hypothetically - If you have an adapter from Amazon, and one from them directly, and it's the same model, and one breaks. How would you know wether you should return it to them (to China) or Amazon (for free), given that they have no serial printed on them?
 
Just In time for 8.22, I've decided to go back to the wire. I spent some time looking at my next car (2021 Cadillac Escalade) and saw how wireless carplay is supposed to be done. I sent my USB-C unit back to Amazon for a refund -which thanks to Amazon's amazing refund policy I already have. I'll try 8.22 on my CarPlay2Air and see how it is. it's likely going up on eBay or the like soon.
 
A new wireless CarPlay dongle from JoyeAuto with its own firmware?

Interesting, but seems almost the same with the same descrition and even the same list of cars supported. Same problems...?
 
Based on the review from @2018 Denali, I went ahead and updated from 8-4 to 8-22 and plugged directly to my GM vehicle USB port without delay timer and it seems to work well so far, it connects every time and no sound degradation after 5-10 minutes. I haven't gotten the chance to test this over a few days because I just updated yesterday, but will post back observations after some more testing.
