I'm in South Africa and ordered a headunit from the US as they weren't out here yet... not the first time I've done this, so besides for warantee issues, the only problem I've found is the US radio frequencies all end in a uneven number ie 88.1, 88.3, 88.5 where most of the radio stations in south africa end in an even number.

Never listen to the radio anyway, so doesn't bother me.  If you do go ahead and purchase one, maybe make an image of your firmware in case something goes wrong in the future.

Hi guys

Had this problem today, and thankfully this forum exists so manage to rummage through the pages and then put a fix together.  Thought I'd save future people some hassle and just put in one thread (I dont take credit for the IMG, it was found in the IMG thread but here goes)

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)

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

Ok, so first run through, with 4G (my iPhones LTE) disabled and 3G enabled  it dropped twice in a second and then was perfect.  2nd run it dropped 4 times in 2seconds.  Normally with 4G it'll drop a lot with long pauses over 5-10 seconds, so definitely a huge improvement.  Still doesn't fix the problem though.

Still don't get why it's not happening to everybody with the 4400.  I've only ever found one other post about this which I can't even find anymore, and I'm pretty sure the guy got a replacement from Pioneer and that ended up doing the same thing, which almost leads me to believe its something to do with our environment/cell providers/electicity/vehicle.

Anyone else find that there are certain "hot spots" that it happens in, or does it seem completely random?

it is not clipping, it is loss of wireless signal, I experience the same on my 4400, 4500, and a non-pioneer wireless carplay system, it is electrical interference, power lines or something like that likely. plug up the phone and use carplay wired, you will see it never drops......

Yes, sorry, clipping was probably the wrong term, it is a loss of wireless signal. 

This is what I suspect too... the road close to me that it always happens at literally runs alongside power lines.  Strange thing is I have overhead power lines all around me here and it doesn’t happen when I drive under some of the other ones.
 

How could they produce wireless tech that can be affected by power lines?! 
 

then again, surely this would be happening to absolutely everyone using wireless CarPlay and not just some people?

Going to be testing shortly up that road disabling LTE etc to see if I can pin point what’s causing it. 

Hi Everyone

As the title states, my music app has been cutting out/ clipping on and off sound for a few seconds at a time.  Almost feels like its briefly losing connection like when you going out of bluetooth range.  This is using CarPlay in wireless mode.  I tried the other day to use a cable connection, but the cable in the car is not an original apple charger (gave a message of unsupported hardware or something) but the phone still charges with this cable.  The clipping still continued so Im guessing the hu is still using wifi for data transfer.

Then I figured out its been happening at the exact same locations every time.   Find it happens less out towards the country side, but a little more often in the city.  

There's an offramp I use normally once  a week or so, that it consistently happens on, a long ramp about 400m 1/4mile, and now recently at an area that's doing roadworks nearby my house.

Like clockwork it starts messing around when driving in these areas.  The first time it happened on the long offramp, I was convinced my amps ground cable was loose as that has happened in the past causing clipping, and the long hard cornering was affecting it, but nope, it was tight.  Only then started keeping track of the locations where it happens.

Happened with iPhone 7, and now iPhone XS.  Software on both phone and hu have consistently been updated hoping to fix this problem.

What kind of interference (the only thing I can think of that must be causing this) am I experiencing and how do I fix it?

Any ideas?
