I have now been in a mail dialogue with the support at carplay2air over some time now. This is really going nowhere. Only receiving standard replies.
In my first contact I told them about my issues as described above (in more detail of course)
All I got back was a standard reply telling me how to connect it. Of course it still didn't work.
I replied that it is not possible for me to follow their steps as the interface screen disappears so quickly. Also told them that I had tested it in a VW and found the dongle working and got it updated there, but that it still does not work in my Citroen.
The reply I got back: "please try to update your car software"
So I did, which made everything worse. Now the interface screen doesn't show at all. Furthermore now when I have tried to have the dongle connected to my car, the native cabled Carplay will stop working as well until the car has been powered off for some time.
Wrote them back about this, and now they want me to send the dongle back (to China), so they can send me a replacement.
My question to them of course was. Why? What would that help? Then dongle is working. Just not in a Citroen C3.
Haven't heard back yet.
Also now I am pretty sure that the "customer" reviews on their website most likely are fake. I received an email from them asking me to review it. So I did with 1 star review warning people about buying it if they have a Citroen.. It doesn't show on their website after some days. Go figure.
This almost exactly mirrors my situation. Mine worked flawlessly in a MK7 GTI but now doesn’t in either my 2020 Malibu or my wife’s 2019 Equinox with identical MyLink 8 inch displays. I no longer have the VW to try to update the adapter. Their CS is useless. Please keep us/me posted. Thanks !
An update from me.
After telling support for around the 5th time that the dongle is working with other car brands, they dropped the idea of having to replace it.
Instead they now wanted me to upload logs to them, but without any instructions on how to do this.
Their reply literally just said "Please upload the log on the firmware website along with details and bugs you're experiencing"
So I replied back requesting instruction on how to accomplish this, and their reply now just was instructions on how to reset the network settings on my iPhone, and then a request to try to follow the setup instructions again.
JEEZ! I have told them numerous times that this is not possible, since the dongle interface screen does not appear, so I cannot do anything.
So now a new mail to them, again telling them this for the 6th time, and again asking for instructions on how to collect and upload logs.
This is going nowhere except in circles.
