I installed an Atoto S8 (2nd generation) head unit in my car, and I'm noticing that it only reconnects to whoever drove the car last.
For example, I usually drive the car. But when my wife drives, we need to manually go into settings to find the list of paired devices on the unit and then click on her phone to connect. After that, it will auto-connect whenever she drives until I take the car. My phone won't connect anymore unless I go into the list of paired devices and do that same thing. Silly and annoying because we share the car sometimes and have to keep track of who drove last if we want our phones connected.
I reached out to Atoto because their linux-based F7 didn't do this (I owned one previously), it would reconnect to any previously paired device automatically like any head unit should (obviously most recent first, but then if not found move on to another previously paired). They said the Android based units don't work like that, then gave me a silly reason for it that didn't make sense (something about security unlocking which the F7 doesn't have to worry about).
I'm wondering, do all Android head units have this issue or is it unique to this brand?

Just doesn't pair. Finds the device, I try pairing on my phone and it does it forever til it times out. On the other hand my friends phone connects instantly with no wait! Anyone else had issues with connecting to a headunit? Before that I had a Pioneer one with no issues but when I upgraded to a Sony one Bluetooth will not pair on the OnePlus 5.
Think I'm gunna get rid of this head unit and pay £60 more for a Kenwood one.

I'd buy it off you if you were in the US. I think the radios are different though.

I just went halfords and swapped it for a kenwood one. Had to pay £50 more. I haven't got around to setting it up yet so will test later to see if bluetooth works.
I've noticed Bluetooth issues with my car's head unit. It is a stock unit from Subaru. It paired just fine but I have to manually connect every time... And sometimes I have to click connect multiple times before it actually connects.
No problems with other phones on that head unit, and also no issues with other BT devices.

Well at least you're getting further than me lol
My previous head unit by pioneer worked okay, paired instantly and automatically connected as soon as I turned the car on. Let's hope I got more luck with the Kenwood. Finish work in 40 mins so will test then.
Well the Kenwood works great and as it should. I didn't even have to setup Bluetooth android auto did all of that for me looks. Like it's Sony's fault rather than OP

I also can't connect to my car stereo. But my OP5 (OOS 4.5.6, rooted SuperSU) just won't see my MEX-XB100BT. My OP2 (CM14) had no issues seeing and connecting to it.
UPDATE: I managed to pair the phone via NFC. Worked like a charm from the first try.
I have a Pioneer unit (avic f960dab) and my OP5 connects absolutely fine.
Media browsing however does not work at all. Used to work with my iPhone but have never been able to get it working with Android.

For what it's worth, I ALWAYS had issues connecting Android devices to the OEM stereos in my 2011 STI and 2015 WRX. I've since switched to an Audi and those connectivity issues are gone (with both Google Pixel and Galaxy S8). The Subaru OEM stereo is known to be garbage. I highly recommend doing yourself a favor and upgrading it. It will improve the sound quality of your OEM speakers while also improving bluetooth connectivity. It's something I never did but in retrospect, I should have.

I wonder if it has compatibility issues with certain chipsets - my stock Nexus 6 worked flawlessly.

I've been considering upgrading since day one, but as long as my phone connected fine it didn't bother me too much. This might be a good enough excuse...
I got my 6t to pair with the radio by connecting the phone to the radio with the usb for Android Auto. Before connecting using USB I could not find the radio under available devices to pair with. After connecting to the radio the with the USB I was able to see the radio and my phone was trying to connect, kept giving an error 'wrong pin' at this point I just unplugged the USB and the the radio ask for permission to use the contacts in my phone which I granted. Radio is now paired and auto connects.
I have noticed that my phone (OP 5) sometimes (quite often, but not always) requires a new pair process with my car head unit. My head unit is VW RCD330.
For example: two hours ago I came to my office. I listen to my music and use Android Auto on my way. Now I'm looking on my phone and my head unit isn't listed. So I expected that I will be asked again to pair.

Hi all,
First time poster here with some unique issues (at least for me) with one of the newer Android stereo units. (AA0495B)
I've already contacted AUTOPUMPKIN customer support and they were absolutely no help in solving this; I've also done my own testing and tinkering but haven't been able to get anything working so I'm hoping someone here with more knowledge of these Android units can help.
Late last year I got an AUTOPUMPKIN Android 9.0 unit (AA0495B) for my track car; the main reason I got it was to run my track timer apps directly from my car instead of having to run it from my phone in a dash mount as most do; the specific app I use is Harry's Laptimer. Now obviously this app was programmed with phone use in mind, but after a bit of doing I was able to get it working completely on the Android stereo unit, so my questions aren't around that app, but rather some secondary hardware related issues using the unit. Overall this stereo unit has been great and free of any major issues like ones I've seen on other XDA posts about other Android stereo units. The app works, connects to my GoPro over WiFi flawlessly, and records track sessions and syncs to video perfectly. My issue is that the HLT app also supports connecting to other kinds of devices via bluetooth for additional data capture, such as the XGPS160 for obtaining more accurate GPS lap data (The 160 captures GPS coordinates at 10Hz rather than the 1Hz of the AA0495B and most Android phones) and I'm having issues getting the stereo unit to connect to the XGPS160 device.
There are several problems in getting this to work, but to keep things simple I'll start with the first problem and then work down layer by layer as each issues is solved; hopefully, if we can get it to work, this thread can serve as a guide for others to get this stereo unit to connect to this and other GPS devices.
PROBLEM #1 - Getting the AA0495B unit to pair and connect to the XGPS160 over bluetooth
So obviously the first step is to get the XGPS160 connected to the head unit over BT. The instructions for this are fairly straightforward and in the XGPS160 manual which I followed. The AA0495B unit has its own custom UI for managing connections to bluetooth devices rather than using the native OS bluetooth menu. The native OS bluetooth menu can be found in the system menu, however when attempting to use it to pair to devices, no devices are detected. If we instead use the main menu Bluetooth button to open the custom BT interface and then hit the search button to scan for devices, the XGPS160 shows up when ready for pairing, so we know the BT radio is picking it up at least. I then click on the name of XGPS160 and press the Connect button to pair the device. After a few moments, the device name now shows as an "available device" meaning it is paired to the unit (at least in theory). We can then click on the name and click the Connect button again to attempt to connect the device. This is where it stops, as it never shows as being connected. For comparison, the UI does show blue "connected" icons when the stereo is connected to my Galaxy S9. It appears this custom BT UI will only show the blue symbols when the connected device is a phone; I also have an OBDII dongle paired and it will never show as connected from this screen, however apps like Torque Pro are able to make the stereo unit connect to it and pull OBD data from the car. I was hoping that maybe this was a case of this custom UI simply not showing that the device was connected when it actually is, like the OBDII device. I attempted to run the "Bluetooth GPS" helper app to see if I could get it to connect; however the XGPS160 doesn't even show up in the list of available devices, whereas the "OBDII" dongle is listed even though it's not currently connected. Presumably this menu is pulled from the OS's list of paired devices, so if I had to guess, perhaps the XGPS160 isn't really paired even though the Pumpkin custom BT UI shows it as paired?
In contrast, I was able to connect the XGPS160 to my Galaxy S9, update its firmware via the phone app, and install and run the helper apps to pull data from it, so there aren't any problems in the device itself, but appears to be an issue with the stereo unit.
Here are the About Machine details from the unit for reference:

So with all that, does anyone have recommendations on next steps? I'm a software engineer by background (though not in smart devices) so I shouldn't have trouble performing any troubleshooting steps necessary.
thanks!
Figured out the issue
Circling back to update this one for anyone else who comes across this issue. Here's the response I got from Autopumpkin support
"After checked with our engineer,sorry to tell you that our headunit cannot connect to SkyPro XGPS160.the reason is car stereo Bluetooth is equivalent to a Bluetooth headset and it can only be connected passively.sorry about this."
So yeh, seems they cheaped out on the bluetooth module and that's the problem. Now if only I could find a way to disable it and use a USB bluetooth dongle I have instead.
I also have the problem with a Kingbaets K1+ Android 8.1
Unfortunately, it is only possible to establish the Bluetooth connections up to Android 6.0.
Later Android versions have a "castrated" Bluetooth interface.
My consequence was that I bought an OWNICE C500+ with Android 6.0.
With this device, Bluetooth hardware can pair with PIN input.
It works perfectly.

Hey everyone. I recently picked up an aftermarket Android Auto/Apple CarPlay unit for my 2014 Lexus IS. The unit I have is Android 10 with a Snapdragon MSM8953 Qualcomm Processor. I have a couple of issues that I need help with.
The unit connects to my phone through Bluetooth but as far as the hotspot goes, it doesn’t connect at all. Z-Link needs a hotspot connection and my unit doesn’t automatically turn it on for my phone to connect to.
Basically the same as #1 but my Bluetooth doesn't connect and when I do connect it, the hotspot automatically starts up and I have internet connection. So it's a hit or miss when it comes to Bluetooth connecting or hotspot connecting. One connects but the other doesn't. Vice versa.
I’ve noticed in many other peoples Z-Links, in its settings they have the option to “Connect Automatically”. I’m not given that option at all. Is there any sort of thing I can do to make Z-Link start automatically? Rather than having to press the application every time I start the car?
I am assuming that once I figure out how to open the z-link application automatically, both issues 1 and 2 will fix each other.
I appreciate the help! Thank you!

Hy. I had the same Problem with the same Unit in the same Car. I ordered a "only DATA sim for tablets" from my Provider and installed it on the internal sim-slot from the Unit, and my Problem was gone.
The Unit himself can not handle Thethering (also named as Hotspot) with a Cellphone AND the (Carplay-Anroid Auto) Connection to the Unit.
(BT is only to handshaking in the first step but then wlan is used to use Android Auto or Carplay function of this Unit)
I recently installed a Fellostar Android head unit/radio in the car, and we have a problem getting the unit reliably to connect to the phone. This usually happens automatically, via whatever app (can't recall the name) that came installed on the unit for that purpose. *But* sometimes it is flaky, and doesn't want to connect (endlessly "verifying"), even when the cable is plugged into the phone. *And* the problem is much worse if there are multiple phones/users in the car who have connected previously - the head unit just randomly connects to one of the phones, again regardless of which one is plugged in.
Is there a fix for this? Is there some way to choose, from the head unit, WHICH phone it should connect to?? The factory installed linking app offers no such choice. Are better apps available? what and where?? Thanks in advance...
