Looking for an Android headunit but last one wouldn't see hotspot.

I have a Samsung Note 4 and I want to use it as the hotspot for the headunit. The last one I tried (YINUO® Quad Core 1024*600 Android 4.4.4 7 inch Universal Car DVD Player) would see WiFi but not the WiFi from my phone. Anyone have any experience with this or could recommend a good headunit? Please and thank you!
Oh I don't need it to have a DVD but I would like it to either have a volume knob or vol + and vol - buttons.
Again thank you for your time.

Android auto is different from your headunit, yours looks like it is actually running android like a tablet:

Android Auto headunits (like the NEX 4100) will give you maps and play music and will use your phones data connection directly, no wifi hotspot required!

That is a rebadged HuiFei unit, which is probably the best and most popular type of head units right now. It also should be no problem working with a phone wifi tethering/hotspot. It will NOT work with bluetooth tethering though because the bluetooth on them is dedicated to phone/audio only.

Bluetooth Streaming to Car Stereo Question

I recently purchased the Pioneer DEH-4800BT head unit so that I could leverage the Bluetooth capabilities. Everything works great, with the exception of the unit reading my music library via Bluetooth. If I restart my Note 4 and then connect it via Bluetooth to the Pioneer head unit, it reads the library and allows me to browse my music as it should. However, if I turn off my vehicle thus disconnecting the Bluetooth connection, the unit will not read my library without me having to restart my Note 4. Has anyone ever encountered this? I have a feeling there is something on my Note 4 preventing the unit from reading the library a second time without restarting. Unfortunately hours of Google searches on this subject have left me with no solutions. What can I do to fix this? Thanks in advance!

Don't have a solution for you but I have experienced a similar issue with my Kenwood DDX719 that I have owned for 4yrs now.
My work a round is to enable BT on phone after my Kenwood has booted up.
This way it reads all the time , if I stop/turn off the car I'll turn off BT and next time I started up again I re-turn phone's BT back on.
My boot up is the time it takes me to buckle my seat belt, next step is to turn on BT on my phone.
My old S4 would work all the time even if BT was already on before Kenwood boot up.
I searched a while back when we upgraded phones (8 months ago) but could not find a solution.
Sometimes when i'm running around making several stops I'll leave phone in car with BT on and after starting up car Kenwood will display all info no problem but like I said "somtimes" not always.
The only thing affected is my music library, contacts always show up even if music library is missing.

AA Troubles: GPS no data --> AA disconnects

Hi,
After several months using AA in a Golf MY16 with two different smarphones with Android 5.0 & 5.1, using different AA releases, then I have found one "use case" when the AA "fails" (=disconnects from the HU):
* When you're driving inside a tunnel and the car's GPS losses the signal, in this case the AA *always* disconnects from the Head Unit.
Did you have a similar experience?

Hi,
No one with similar behaviour? :silly:

No problem with my 2016 Jetta. Google Maps says me that GPS signal was lost but there is no error. Are you sure it's using the car GPS ? I find it is not very accurate at some places.. Which phones do you use ? I found Marshallow more stable than Lollipop with Android Auto. I had connection drops with 5..1.1 but it was random and not related to GPS signal lost. No problem at all with 6.0.

Thank you for the report! I'm using Lollipop 5.0 & 5.1 in two different smartphones. I'll check with some spare MM 6.0 when I have time.
:good:

you are welcome.
It seems that Android Auto is using the phone GPS (at keast with the VW head unit) Just try to disable the phone GPS before connecting the phone to the car and start Maps : you will be asked to enable the GPS. Really sad.

Hi,
If it's true that AA is using internal (phone) GPS instead of car GPS (almost in a Golf MY16), then the problem can be when the PHONE losses the GPS data... Even, I feel the real problem is: the phone likes to say "GPS disconnected" and the disconnection ocurs because some trouble exists with the audio output.
I also detected that sometimes when a WhatsApp is received, also the AA is disconnected. I hope Google can fix this trouble with the "AUDIO OUTPUT".

Yes I got something similar when trying to run Waze in the background. Waze audio notification made the connection drop. It was with 5.1..1. I can have a try with Marshallow.
UPDATE : no problem at all with Marshallow (CM13) : I was able to run Maps and Waze at the same time. Got Waze audio notifications. No USB connection drop. The only issue is my Nexus 4 did a shutdown because it was overheating but it's a common issue with the Nexus.

Thanks for the info! :good:
I suspect the problem is then related to the audio route inside Android 5.x

Hi,
More info:
Using Android 5.x, VW Golf MY2016 with CAR GPS, and last AndroidAuto App, the GPS signal is comming... FROM THE PHONE! So, yes, VW is not sending GPS signal to the AA process. In this case, when the phone losses the GPS signal, the AA process crashes. This is then the problem in my system: when GPS signal is lost inside a tunnel, then the HeadUnit disconnects with the AA process.
I hope Google fixes soon this problem. Also, I hope VW can upgrade the MIB software for sending ALL car data (including GPS position and ORIENTATION) to the AA process.
Regards.

And hope a droid will accept that data.

Yes I'm afraid AA is too much complicated. It crashes for many phones. Manufacturers doesn't implement all the features but imagine you have to build a head unit with GPS, Car Play, Android Auto, MIrrorlink... and all these subsystems (that does the same job : screen mirroring) have to send car and gps data to phones. using all the protocols. That's just crazy. And when it works you get frustrated because of usage limitations.

BT keeps stopping

I just noticed that phone is not connected to my bmw car kit most of the time, because BT keeps stopping. Now this is a show stopper for me. This seems like yet another cheap Chinese device which has nothing to do with Nokia.

Any other people who have the same problem? I do need BT all day for headset and connection to an OBD-device..
Gesendet von meinem EVA-L19 mit Tapatalk

I'm connected all day and night to a Xiaomi Mi-Band 2. BT never disconnects from it.
Also when I'm driving, I connect to a 2nd device which is an MPOW bluetooth receiver connected to the car's aux port. Also never experienced the BT stopping or dropping the devices (2 simultaneously, yes, using Oreo beta).
Dunno if this helps or qualifies to compare what you're experiencing.

I experience the same Bluetooth disconnections while using my Parrot carkit. Unusable for now. Running on Nougat oct security update

People report about car connection in other phones too, I think it's might be a OS problem. For me I use bluetooth headphone, never get disconnected. But sometimes have audio drop out when moving.

I have a slightly old ford kit.
Yes Bluetooth on it seems a hit or a miss. Connects and the audio comes for a few seconds and then just stops. Calls or audio just stops to work
I would like to blame the phone since my old Nokia 808 and galaxy S6 work fine but my brother's one plus 3 has the same problem.

Bluetooth audio plays just fine over my Volkswagen stereo BUT the play/pause/skip doesn't work and the song info (metadata) doesn't display.
Really frustrating as it was working so well before on my Huawei P9.
I'm running 7.1.1, really hope Oreo comes quick to fix this ?

This was the not very useful advice from Nokia support.
You may have guessed that it didn't work and I'm back using my Huawei... Looks like this phone will be going back to the seller by the end of the week.
Unless Oreo magically comes to save the day. Anyone want to place a bet?

Nokia implemented Bluetooth version 5 so maybe there is a compatibility issue.

Thanks but it was my understanding that Bluetooth versions are backwards compatible? It's a 2012 car stereo and I've tested 2 other Nougat 7.1.X devices which work perfectly.
Music does play from the Nokia but it's the controls and song info that is missing.
I'm back to using my Huawei P9 as my daily driver because of it

So it seems as if there are mostly problems when running Nougat, while it's working under Oreo.
Will watch this thread before going for a new handset. Quite unsure between Mate 10 non-pro, Nokia 8 and OnePlus 5/5t. Dual-SIM is absolutely necessary for me, in Germany they use band 20 (800 MHz) in many areas. As I'm using a Samsung Gear S3 and that OBD-device in my car and furthermore a BT headset, a bigger battery or more efficient device is what I'm looking for.
Seems as if this is getting hard to decide...
sent directly from my mind using my upper extremities..

I'm seeing issues on Nokia 8 with Ford audio in my van. It's not that it disconnects, but when skipping to next / previous song in Play Music, progress indicator continues to move, but no audio comes out unless turn off Bluetooth and back on. Happens when using onscreen skip button, or steering wheel skip buttons. Same worked fine with Nexus 6.

I am using my Nokia 8 for about a week with Ford Ranger (about one year old) and completely there is no any issues.
Regards

A workaround (of sorts) for me is to cycle through the inputs in the car dash (bluetooth, aux-in, fm1, fm2, dab, then back to Bluetooth) which brings audio back and the skip/next buttons work as intended.
Should also clarify that it is not just Play Music. Same issue in Castbox, so not app specific.

Fired up the Nokia 8 last night and see there's a November security patch being rolled out.
This seems to bring my kernel version up to Nov 9 - hopefully this might have an effect on the Bluetooth compatibility and stability?
Haven't had a chance to test it yet but it's going back on Saturday morning if not fixed...

I have only connection problems with my Parrot 3100 carkit. Connection drops when calling. Bluetooth connection drops randomly. Stays connected when not calling. No issues with other Bluetooth devices.
The November update did not solve the carkit issue. Unfortunately. My hopes are on Oreo..

My problems are still persistent on the new November kernel.
I feel like this will be a forgotten device once the Nokia 9 is released in the New Year...

Would any of these Bluetooth developer options help those having issues?

I believe these are Oreo specific and despite the fact the rollout began yesterday it's yet to hit my phone. Fingers crossed, I've extended Nokia's deadline until Monday ?

Dual Audio feature cut since update from Android 9 to Android 10

Hey guys,
there is a feature cut in the Dual Audio functionality since Android 10. For most people, this might be not a big thing, but for people who are using dual audio while they workout, this feature cut might be very annoying.
The dual audio function of Android 8.x or 9.x was ablet to reconnect to both connected bluetooth speakers/headphones when the connection got lost, for example because the distance between the mobile phone and one of the headphones was to big or something like that. Also, when you switched on two paired bluetooth headsets, Android 8 and 9 was able to connect to both devices automatically.
Since Android 10, only one headset can connect automatically to the note 9. I always have to connect the second device manually. Once this is done and the connection to one of the two devices disconnects for some kind of reason, you have to reconnect the second device manually again.
One more annoying thing is, that when you are connected with bluetooth headset 1 to the mobile phone and activate bluetooth headset 2, the active connection will switch from headset 1 to headset 2, which means its possible to highjack the connection between note 9 and headset 1 with a paired device.
This is very annoying during a workout, because nobody wants to pause the workout to reconnect the second bluetooth device again, espacially if you are carrying the device during a run in a bag of your clothes, or a saddle bag, in you bag during a workout at the studio...
Are there any solutions to get the automatic functionality from Android 8 or 9 back? As far as i can see, this problem is also on all other samsung devices with android 10 and dual audio functionality. This issue came to alle devices since Android 10 with One UI 1.x.
This problem is adressed in the german samsung community forum, but till now, without a solution:
