Alright, trying to figure this whole mirror thing out.  Recently purchased the AVH-4000NEX unit, and I have a AT&T Galaxy Note 4.  I'm trying to see if there is a way to get the full on mirror and control of my phone on the head unit screen.  I don't really want to root my phone (and not sure if I can from what I've read), so the ARUnchained option is out.  So I saw the ARLiberator option.  However, it seems like this won't work on the NEX units?  Is this true?  Has there been any updates to allow this to work?

If that does not, is there any other options to get this to work?  I believe I need to get an MHL adpater and plug the HDMI and USB into the back of the headunit (USB into the lower port, correct?).  Then the micro USB goes into my phone.  But this alone will have limited ability and will not do what I'm looking for, correct?

Thanks for the help.

Ok, really stupid question.  If I have a MHL adapter and plug from HDMI to my Note 4, will this simply do what I'm wanting and mirror to the 4000NEX?  Similar to just plugging it into the TV?

If you plug it into the HDMI port via an MHL adapter, then yes, it will mirror your device. However, you won't be able to control your device through the NEX's touchscreen. For that, you need one of the apps you listed above. 

Will the display match on the screen through the MHL, or will the aspect ratio be weird?

I have an 8000, and have no problems with the aspect ratio. 

Thanks

Ok, new question.  So I know the bottom USB is for the android and the top is for apple.  Does that mean that the top cannot be used if I have android?  Or can I run the USB adapter cable they provide to the OEM USB port on my dash for my flash drive?

I'd check USB 1 to see if it's used to update the radios firmware on the 4000.

I have a USB cable inatalled on USB 1 for firmware updates and to add personal background images.  I do use it for a music via flashdrive when I loose cell phone signal driving x country. 

I can't say connecting the radios USB cable to your vehicles USB port is possible because I don't know what your driving.  If you have a Honda, the answer is a definite yes.

I have a 2014 Toyota 4Runner.

Check Metra/Axxess for an adapter.  These adapters don't plug into the back of the USB port but plug into the wire harness in the dash.  I don't see one specifically for a 2014 4runner but that doesn't mean the ones they make for other model years won't work. 

eBay has several USB ports that can easily replace your existing USB port.  This might be your best bet. 

Alright, so things worked like I thought. USB cable in USB1 port for flash drive and HDMI MHL connector for mirror with USB from MHL in USB2 for charging.

Only thing is the mirror image of my Note 4 doesn't quite fit the screen. The aspect ratio is a little off. Any way to adjust this?

You need to use a different launcher with Samsung phones.  Apex, Nova, Google Now, etc.

Sorry, but what do you mean by launcher?

This is how Touchwiz displays in landscape.

This is how an alternative launcher displays in landscape. I use Nova Prime but Apex, Google Now and others will work just as well.

But these are apps to run, which doesn't give the full use of your phone like a true mirroring does, right?

Sorry, but what do you mean by launcher?

go to google store and search launcher, or search Apex, Touchwiz, or google now. You install it and pick it as launcher. It will ask if you want to use the launcher only once, or set as default. I would google "android launcher", it should explain.

Correct, you still need root to utilize ARUR.

You may have to root to utilize launcher too, i can't remember. My Samsung S5 Sport is rooted, so it wasn't an issue.

So without rooting phone and just mirror through MHL, there is no way to get mirror image to fit while screen?

You don't need root to mirror using the HDMI input.  You only need root to control the phone via the head unit.  Sucks that the bootloaders are locked on the ATT and consumer version Verizon Note 4's.  

You can use all of the launchers I listed above without root so that the phones display is potrade properly in landscape. 

Everyone I hook up my Nexus 5 I get the display on my 7000 NEX but whenever I to scroll from page to page I have to scroll up or down. Also whenever I touch an icon it opens up the wrong app. What can be the problem?

Okay guys, I just got the 8000nex and bought a hml for my rooted Note 2. I was able to mirror, but AR Unchained will not connect. I got ARliberate to connect, but no control. What am I missing?? Do it work only in Stock ROM or can it work on custom ROM? I'm running Jedi Master X android 4.3... The reason why I got the 8000nex is to fully mirror my note 2 since my old AVH-X4600BT doesn't sport a HDMI port. Thanks.

The Note 2 is a pain in the ass to set up for the 8000NEX. What MHL adapter do you have? Are you on AR Unchained or did you purchase ARUR? When you go into your Phone Settings/About Device what does it say under SE for Android status?
