Appreciate those who have works really hard getting the gps to work on gear using Null rom with bluetooth gps but with this the gear can only stand for less then a few hours. Gps on gear will need external battery charging for it to works.
Probably someone can work out of a solution how to remote access phone which have better battery capacity and gps receptions running mirror on to the gear, something similar to running vnc or teamviewer accessing remote computer. Hopefully with remote accessing we can do lot more of peaking our smartphone via gear.
Does anyone understand why Android Auto actually requires USB to be plugged in (at least in the Sonata)?
I am also interested in this. But I read somewhere (take it with a grain of salt) it will only use WiFi in the future. But here is my question - When I use WiFi, data connection goes off. So how would data requiring apps such as Maps or Google Music work?
WiFi tethering would be a battery killer.

Your car doesn't have a power outlet?

Exactly, and that's the main reason why USB is the primary method for Android Auto <> HU connections.
Many HUs do not contain GPS, so the phone GPS is used, and that eats a lot of power, particularly for navigation, Waze or any app that uses regular GPS updates.
Bluetooth does not have the bandwidth needed for video, never mind adding high quality audio too.
Wifi Direct is the secondary method for Android Auto <> HU connections and it works right now using my HU app. Google may have issues to try and fix before they make it official; they haven't even announced it yet, and if there are too many problems they may never announce or ship it.
Apple Carplay is expected to add Wifi support in the coming iOS update. It was supposed to be out earlier but likely it had problems.
It remains to be seen how (un)reliable AA and CP are over Wifi, in noisy RF environments in traffic. If your phone is in your pocket while Wifi tethering and doing navigation, it may get uncomfortably hot while draining pretty fast.
I think that for many people, the "inconvenience" of plugging and unplugging will be outweighed by the inconveniences of hot pockets/purses and drained batteries.
The story would be different if most of the "smarts" were inside the HU and the phone simply shared/synced some info (though just Wifi tethering alone can create heat and battery drain issues). The current model is that most processing occurs inside of the phone. This helps keep "ecosystem advantages" in the hands of Google and Apple, instead of the car and HU OEMs.

The comment was about what happens if AA only works with WiFi. And you wouldn't always need to plug in (e.g. drive to the corner store), just for extended use.
Even when plugging in it's far preferable to USB networking - when using a USB (2.x) data connection, the phone is limited to drawing 500 mA by the USB specification. For many (most?) phones, that means the battery will drain if doing tether/GPS/cell data, and even if a phone can keep up with all of that, it will charge slowly. If doing a WiFi data connection, the USB charging spec can be used, and the phone can draw up to 1.5 A, enough to do WiFi tether, GPS, cell data and charge simultaneously.

If AA ever officially supports Wifi, it will be in addition to USB, as it is now. And other connection methods may be added in future, like Ethernet, but that will be more needed for "Android in the car" that runs Android on the HU.
You are correct.
The USB charging/powering limit also arises when people use USB Host mode or regular USB device mode for various reasons. Some devices have custom kernels that can bypass these limits, but that can create some issues as well.
Didn't see anyone mention the fact that media streaming is done digitally over USB - providing much higher audio fidelity than over Bluetooth. This could also be done over WiFi if/when that option comes to AA.

Not always.
My Pioneer 4100NEX is VERY insistent on putting audio over Bluetooth, and it won't even fail over to USB when the maximum of 3 BT devices are paired; just endless error message popups.
And there are at least 2 possible ways to put audio over USB:
- One is via Androids audio for accessory mode protocol, which only supports output (not mic input) and only 44.1K, 16 bits, 2 channels.
- The other is Android Auto's method which tends to use 48K, or 16K for voice.
My 4100 only connects to voice over Bluetooth when android auto is active. Media goes through usb
The 2.4 GHZ ISM band is *so* overcrowded already and is getting worse each year. Bluetooth, wifi and now the MNO carriers want on on that spectrum. A wired connection has *got* to be better in long run.
USB C which has native support for video, seems like the answer.
i will be getting a Gear VR with an S7 in the next day or two... has anyone used trinus VR to stream games from the PC ? how is this experience? is it worth doing ?
I read somewhere I could stream using a laptop nvidia 960m live stream function, does anyone know if this is possible.
Tried this today with trinus and elite dangerous.
I works but the quality is so poor.
I'm hoping when I get home that using a faster Internet connection will help.
YOu can try moonlight or Sideload vr
Sideload VR has an app called Stream Theatre. It utilizes Nvidia Shield on a computer that has an nvidia capable card (I think the minimum is a GTX 660). It's not perfect getting started up and can be a pain up front. but once it is running, it runs very well. It loads a steam OS like platform into the theatre screen native with the Gear VR.
Although, I'd like to stream from my laptop (Intel HD4000) and have not found a way to do that yet.
Edit: Nvidia shield can be found in the Geforce experience app on the computer.
check out this https://riftcat.com/vridge pretty cool though i had problems connecting the connection kept dropping

interesting...wondering how this works, thanks!
Hi,
The samsung gear VR have the micro-usb for charging the smartphone but can't use the usb mode to connect for the pc. I want this for streaming the game (TriniusVR) on pc without using the wifi source of latency, it's can be possible without touch the hardware of the product to activate the usb mode ?
Thanks,
This game is on Google Play too.
Not sure if is the same.
And your idea is good. Connect Gear VR with PC and using it like Oculus Rift wil be perfect.
Hi all,
A few years back I made a system for in the car based on a Raspberry Pi 2, it incorporated a Rpi2, a hdmi splitter and OSMC installed. I made 2 7" IPS LCD screens with custom made housing that attached to the front seat head rests. This way I could play movies in the car for the children when we were traveling with the car. It really worked well and I could control the movies by using the wifi access point feature in OSMC and the Kodi remote control app for Android.
Downside is that both children (a girl and a boy) have to watch the same movie and now that they're 6 and 5 there's a constant struggle as my son doesn't like barbie movies and my daughter does not like teenage mutant ninja turtles!
So, I want to make a new one. My plan is to use a Rpi3 as media server with hard drive attached and kodi on 2 android tablets connected via Wifi to the Rpi3. This way it must me possible for them to choose and watch their own movie seperately.
Is this possible? And is the internal wifi adapter fast enough as I didn't have too much luck with this (very unstable en below average speeds). I could also us a Wifi access point connected to the RJ45 network connector. Or buy the new RPi3+ which has a 300 Mb network port and maybe improved wifi?
I looked everywhere for some guide but I don't seem to find it.
Anyone good tips??
Yeah it's surely possible dude/dudette. But the question is would it be entirely practical is a different story.
The RPi 3B+ has the network capabilities you are after (as long as you're not streaming 1080p across the network for both tablets), the only thing is for it to be effective would be the tablets need 5ghz connections also to utilise the 5ghz networking speeds. I don't have the data sheet on hand which tells me the speeds but 2.4ghz certainly wouldn't suffice both streaming.
The only problem you would encounter would be is Read speeds of the RPi 3B+ and is it worth destroying a hard drive by putting it in a car (vibrations/G forces *if you crash*) is it worth it? I know HDDs are cheap these days so it might not even be a worthwhile issue in today's world.
I wouldn't bother with an ethernet connection, you could utilise the USB to RJ45 Gigabit speeds it apparently allows. Yet again Read speeds might be the downfall on SD cards unless you have a uber SD card.
