I had the same activation problem, but this morning everything is fine. It looked like a problem with servers and could not be activated.

true, my Carlinkit Mini is working again too..... weird 🤷‍♂️
 
Hot off the press - LATEST 4.0 Firmware - 2022.07.29:

Please do not update if you have a 3.0 or earlier device. This is only for 4.0 devices.
I’ve been using the 4.0 with the June update in one of my Mazdas with only about 10% of the time it crashes after connection and or never connects. It’s also slower connect but I chose to keep it because it seems to not have the 70 minute crash that the 3.0 does.

I see lots of people having trouble with the July one, does it seem safe to upgrade?

It's been working fine for me ever since their activation servers or whatever that was came back online.

Hi,

I have a U2W Plus dongle with 2022 01 24 firmware
i would like to upgrade but OTA says it is already latest firmware.
Do you know where i can find a firmware to update ?
thanks
 
What’s the best, reliable, most compatible as of today?

Done a search on Amazon UK and there are loads of types etc now. Do they all check same sever for updates etc?

Any recommendations please
 
I have a Carlinkit 3.0 and today it showed a new version July 2022. I tried to update it via OTA but update failed :( I read that the July 2022 version is only for Carlinkit 4.0. Is this correct? If yes, why was this version showed to me?

Now it was updated to January 2022 but now I have the green UI. How is it possible to update to the red UI?

The general and official advice regardless of model is if it is working satisfactorily then do not update.
 
I can no longer get my CARPLAY2Air to work after the last update. It goes into an endless connecting loop but never does. I have heard there is a way to roll it back to an earlier version. How do I do this?

Thanks.

Hello again DeanCorp.

Don't worry, finally I could solve everything thanks to piotko (user from here), who sent me a private message.

I followed his steps:

1. First I Installed 2021.08.24_BASED to the dongle from here: https://github.com/ludwig-v/wireles.../tree/master/Custom_Firmware/2021.08.24_BASED It was necessary to install it with 2 more files: ARMimg_maker and U2W.sh from here: https://github.com/ludwig-v/wireles...mware/Scripts/RestoreNewEncryption_2021.03.06 It worked!

2. Then, I installed the 2022-01-24 version from https://projects.grabher-industries.com/U2W/ It also worked!

3. After that, I tried that firmware in the car and restored everything to factory defaults. The car recognized CarPlay again for the first time after many days and I could sync my iPhone with the dongle. But I noticed few problems, the most important that the dongle never connected again automatically to Carplay as it was doing before when I entered the car, so I needed to unplug and plug the dongle into the car's USB port each time I wanted to use it.

4. Then, I tried to install again the official firmware that CPLAY2AIR sent me through facebook some days ago (they called it the "1.24 system version") that it was impossible to install before today and... voilĂ ! This time it worked! I don't know why, but now it worked!

5. Finally, I restored everything again to factory defaults and connected the dongle to the car for the last time. Now everything is working perfectly, synched to my iPhone and auto-connects automatically after few seconds each time I enter the car.

So, I think I've learn the lesson: if something works, don't touch it! Maybe the fault was when I tried to change the name of the adapter's bluetooth connection and customized it in the new configuration site at 192.168.50.2. I thought that if it gives the option, should not cause problems. But... the problems started after that. So, I think I will not try to change the WIFI and BLUETOOTH names anymore. Now the defaults are "MAZDA1" for the WIFI and "MAZDA-8585" for Bluetooth. I would prefer something like "CPLAY2AIR" or maybe "MAZDA 3" or something like that but... never mind! Now it works! So I don't try to change nothing. "MAZDA-8585" will be ok for me, at least for the moment, haha.

I also noticed that the firmware that they send me has a completely new user interface now in the car that I've never seen before, even different than the 2022-01-24 version that I installed some hours ago. I like this new user inverface very much!

So, thank you all for your help!
How can I get that firmware they sent you on Facebook? Mine will not connect since I did the last update.

Thanks.

I think there is something wrong with the latest OTA that is breaking devices. My older CPLAY2air has worked like a champ until I did the most recent OTA. Now it boots, and will show "connecting" and just loops there forever. I can delete the phone, re-pair, but it will never get past "connecting". Tried with three different iphones on combinations of iOS14 & 15.

I've been trying to flash various firmware, but none of them ever seem to take. Just a solid red light on the unit. Any suggestions?
Did you ever get it to work? I now have the same problem with the solid red light.

Thanks.

Peter
 
After this I can only say LOL

I upgraded my Carlinkit v2 to the latest firmware, but it was crashing every 20 minutes (my car is a 2020 VW Golf) so I rolled it back.

Now everything works fine (it’s running 2022.01.24.1903) but the connection screen does not have any color. Before the rollback there was the red UI but now the background is black and there are white words. As it connects very fast I can’t do any operation on that screen. I will see on Friday when I receive my new iPhone if I can delete the current one and add the new one.

My carlinkit 4.0 took the OTA update, connection speed seems a little better. I’ve had it installed for a week now and randomly got this one time. Power off and on resolved it…
 
I have Carlinkit 3.0 and my Seat Navi keeps crashing sometimes. Have the latest firmware installed.
What could be the reason? Is the cable that came with the carlinkkit good? Is there another firmware I can try?

Thanks I’m advance.
 
bonasera

ho un problema mio il carlinkit fisso su luce rossa e non rimane si connette piu , ho fatto numerosi tentativi con i firmawere ma non mi carica nemmeno quelli. come mai? aiutatemi
 
I have a pretty bizarre observation and was wondering if anyone also encountered this. My carlinkit 3.0 is working almost perfectly fine but always crashes in one single location. Earlier i thought it's time related (because it happened a similar amount of time after leaving home) but apparently it's either some sort of radio interference that appears on that exact road or maybe GPS coordinates are crashing the system somehow. Toggling GPS in settings changes nothing and it does not happen neither in my 2018 BMW, nor in a pretty new Pioneer HeadUnit, both with wireless connection.
 
lol at this thread. Took a flyer and picked up a Carlinkit 4.0 (at least that's what the Amazon listing said it is). Connects for 2 or 3 seconds and then immediately disconnects.

Thousands of forum comments detailing all manner of horrors and have decided this is a hell not worth spending any time on. Back to Amazon you go, piece of junk.

I'm in the same boat. I would like wireless CarPlay but at the same time, I'm not sure it's worth the aggravation people seem to be having the more research I do on it.
 
This is a VERY YMV product. For some cars it's completely plug and play and works pretty much without issues. On other cars it only works after fiddling with settings, with crashes, etc.
The way to go on these is get them somewhere you can return them easily.
Step 1) Try it out, if it works fine, don't touch it
Step 2) Update it, repeat step one
Step 3) Either fiddle with settings or return it, depending on how much you want it
 
Another thing to remember is Updates are not necessary cumulative like ios or Android Updates. When they release a Wireless CarPlay Update they may add a new vehicle for compatibility and completely stuff up all previous working vehicles.

There is a lot of research & reading in these forums trying different adapters and then picking an Update that works for your car. A lot of trial and error.

Also Adapters come in V1, V2, V3, V4 etc. Which one is suitable for your particular Vehicle is another trial and error situation.

But once you get an Adapter & Update that actually works correctly you will not want to go back to Wired CarPlay again.

I knew this will happen. I can't delete my old iPhone so now I have 2 iPhones with the same name. As you can see the interface has lost some colors and buttons. I have some panic about reinstalling the firmware as I had other Carlinkint in the past and it died.

I will assume you have U2W firmware.

Go to 192.168.50.2 and reset your Wireless Adapter. Hopefully that will reset it back to factory settings. Unplug Adapter.

Also delete all pairings from your iPhone Bluetooth & Wireless Settings, restart your iPhone.

Then plug in Wireless Adapter to your car’s USB and hopefully you can pair your iPhone & Adapter again.
