When I connect my iPhone 14 pro to my pioneer 4400nex wireless car play radio and turn off the car and turn it back on the radio doesn’t auto connect and if try to manually connect it shows my old iPhone. I even did a factory reset of the radio and it still some how sees my old iPhone. But in order to reconnect I have to go to CarPlay settings and forget the car and then reconnect. But same thing happens every time I shut the car off. Just to test it out I reconnected my old iPhone 12 Pro Max, and it works perfectly, remembers the device and reconnects after starting up my car. Not sure if this is an iOS issue or if a new firmware needs to be developed for my radio. Anyone else seeing weird behavior?

Exactly my problem !!! With the 14 ProMax, I’ve reset the 4500Nex and all and it will only connect after clicking all the clicks and Bluetooth crap again and again but restart truck and won’t do nothing-

Pioneer and or apple need to fix this. I’ll have to connect with a usb cable until it can be fixed.

I just called pioneer and they said it’s an iOS bug. I see there is a new iOS 6.1 beta I may try once it’s released to the public and hopefully has the gps bug resolved to see if this corrects the CarPlay issue.

I received this response from email support

“On the car battery , disconnect the black terminal for 10 minutes and reconnect it. This should help the unit to clear any glitches as a soft reset. If the issue persist the unit may require repair.”

I did disconnect my battery and it made no difference.

I installed the current 6.1 public beta and it made no difference. Maybe public beta 2 will come tomorrow.

Beta 2 made no difference

I fixed my CarPlay issue. I had to take it apart and replace the internal SD card with a fresh copy of the operating system. It was quite the ordeal. No issue with Apple, issue was with pioneer making a poorly engineered product (or bad software). Fortunately it was relatively easy to fix.

I also cut a little bit of the cover to easily replace the SD cards if it goes bad again. But it’s working perfectly again. I am a bit critical with pioneer that they didn’t create better software (and abandoned support) but I’m happy it was easy to fix and it’s a pretty good head unit. When you factory reset the radio it doesn’t totally reset because it remembered my old iPhone and i believe that was the issue. If pioneer developed it to really factory reset it would probably have been fine.

I had the same problem, mi iPhone 14 ProMax didn't connect wifi with Pioneer AVH-W4400NEX. Before trying the above, I connect the iPhone 14 ProMax via usb, and there is an option that says, connect with wifi, I tick that option and solved the problem. My new iPhone 14 ProMax is working with Pioneer AVH-W4400NEW
 
Posting the directions here because a few days ago when I tried to access the AVIC site it was not working. Not sure if posting links in here is forbidden but will give it a shot

This will repair the boot loop loading screen.

First off, you'll need a replacement SD card, the one I used was still stuck in the headunit as I used to use it for firmware updates and had a few tracks on. The image file is just over 8gig but I used a 64gb one because it was what I had. I'm sure a 16gb would work fine. This was formatted to ex-fat.

Here is a link for the IMG file download (credit to Jamesl75 who posted it on the other thread)

https://mega.nz/file/SdJCgKCJ#13zrFlogMCWNohCvuFsDFcC1uniHgufVZJxZlQPHUag

Once you've downloaded that file, unrar it and save it on your desktop.

Next download win32 disk image https://sourceforge.net/projects/win32diskimager/

Open win32 diskimage, open the img file from your desktop then select the SD card drive... lets it do its thing for 4-5 minutes. Note the finished SD card was unreadable on my laptop... at first I thought this was a problem, but turns it it worked perfectly fine.

Next involves the stripping down of your headunit to get to the memory card. I used this youtube video below. Did everything except disconnect the last ribbon connecting the metal face backing to the unit... managed to angle the black plastic backing to give me just enough space to get the old card out and the new one in.


Then fit back into your car and it should work!! It did for me, and literally took me all of 20 minutes of get done and enjoy your working headunit again
