Hi, I am looking at buying a Pumpkin double din head unit that has the option to attach a usb 3g dongle for direct connectivity. However I intend to install a roof mounted combined gps and 3g antenna for better reception, therefore I would like to buy a usb 3g dongle that has an external antenna socket. Can anyone recomment one that is android compatible, or am I able to buy any dongle? The dongle that Pumpkin recommends and that is also mentioned in a similar recent thread does not have an sma socket.
Although I know it is an option, I do not want to connect via wifi.
thanks in advance
Hi! I got an PX5 headunit with Malaysk rom android 6
I tested the modem on my computer and it is works fine, but when i connected to the head unit it seem like not being recognised, the 3g HSDPA dongle is for Pumpkin car stereo so theoretically it should work.
Any idea what to do next?
Thanks!
In further investigation, I found out the problem is the head unit can't see the USB dongle. It is connected to the 3G/Wifi USB port, my guess is the problem it's not just a 3G dongle, it is a micro SD card reader as well. Any idea?
This is a Joying for a vw. Running android 8.
There is two usb connections at the back. Left and right.
The one marked 2.o (left one looking at the front) works with the DAB adapter and Zlink Apple car play. All is good.
Q1:
If i connect to the right usb the iphone then zlink wont connect. Why? (Im assuming its USB1.0) Can I use one of the zjinnova adapters to get carplay on this usb port?
Q2:
If i connect the DAB adapter to the right usb it works but the sound stutters enough for it to be annoying to listen to.
Anything i can do to help this? Im assuming its a data speed issue.
Q3:
Any tips on getting both DAB and Apple carplay to work?
Regards Kurt
Hi all.
I have a 2021 mazda bt50. Supports all phones. Wireless carplay, wired android auto.
When i plug this device into the usb port for connecting to the stereo. The device just constantly reboots.
If i plug into a normal usb port (charging only) the unit stays on and does not reboot. But unable to connect to stereo.
Have done all nessasary firmware upgrades.
I have tried new cables everything. Nothing works.
Another supplier that sells thses things rekon they have them working in my type of stereo. But mine just reboots.
Can anyone help?
Thanks heaps
Craig
Hi all,
I'm having an issue with my Joying 8.8" Android Unit. The unit supports Android Auto using the pre-installed "CarLink 2.0" app.
I usually use Wireless Android Auto and it works just fine. However, the head unit does not have any buttons, neither does the steering wheel (Audi TT mk1). To solve this, I have added a USB volume dial (Digispark ATtiny85 paired with a rotary encoder) which I have used on another car running a eonon unit with ZLink where it works very well.
The problem is that, everytime I connect the volume knob to this unit's usb, CarLink seems to think it is a mobile phone, so it interrupts my wireless android auto session and attempts to connect to the usb volume dial. When this happens, the volume dial stops working. This only happens when the CarLink app is running.
Thinking this is an issue with the CarLink App, I tried to install ZLink instead, but It won't run due to "channel error". Do I have to install it as a system app?
Another possible solution: Is there a way to disable USB for CarLink?
Thank You
What did the reseller suggest when contacted for support? What else has been tried?

I contacted Joying with no answer yet (It's the weekend, they might reply next week).
I tried using different USB ports, USB hubs, USB adapters, changing available configuration.
Interestingly enough, using USB A -> USB C -> USB A adapters made the knob continue working even after CarLink tries to connect to it, but still interrupts an ongoing Android Auto session.
I ended up figuring out the problem. Turns out that certain USB class/subclass identifiers are not properly handled by CarLink. Making the microcontroller report a different combination of usb class/subclass did the trick.
Interesting problem. I just installed a 9" Joying radio into my 2019 Honda Civic Hatchback EX, and I forgot I had an iPod plugged into the USB in the middle storage area. I could not get Wireless CarPlay to work reliably (if at all).
I know the radio does not talk to an iPod, so I moved all the music to an SSD drive on USB3 in the glove box. However, if the drive is connected, Wireless CarPlay will not connect unless I disable and re-enable Bluetooth and reconnect manually, but then it disconnects the USB hard drive.
I don't have the option of changing VID/PID values. I am waiting to hear back from Joying, but thought I would add this to the thread as it is somewhat related behavior with CarLink 2.0.
