Display: Every unit has nowadays on the top-left the On/Off button.

Tap it once: Mute sound / Re-enable sound.

Hold it 3 seconds: The screen will completely switch off. Tap any button to switch it on again.

The Chinese have no idea how RDS-AF works. It is not being used in China. "NPO 3FM" is on the same frequency throughout the entire country in China.

What they implemented is that when you enable it, it simply searches for the strongest stations (frequencies) it can find. Not the strongest station for that specific radio station. Already since 2015 an issue and never solved. That is why so many people use DAB+ (including me using @realzoulou's excellent DAB-Z) which has proper "service following" (as RDS-AF is called on DAB), which allows you to listen to NPO 3FM from Delfzijl to Cadzand without touching your unit (well, maybe the volume in case of a very good song ;))

Edit: a DAB+ unit on Aliexpress costs anywhere between 25 and 45 euros (Joying 60 euros. Don't buy). Mostly the DAB+ apk delivered with it sucks, but that doesn't matter as there is DAB-Z.

Edit2: I moved my DAB+ dongle from my PX5 to my sc9853i and now to my uis7862. Simply replacing the self-adhesive window antenna once going from my previous car to my current car (8 euros as far as I can remember)
[FYT Android Head Units] Solvin:
True story. DAB-Z for DAB+ and NavRadio+ for FM/AM.
[FYT Android Head Units] surfer63:
NavRadio+ supports RDS-AF on MTCD and TS units, but the MCU does the heavy lifting on the FYT units and does not support RDS-AF (as it is designed). Therefore Navradio+ does not support RDS-AF either on the FYT units.

I believe actually the screen doesn't completely switch off: the same action can be performed, by drop-down bar. The way I discovered it wasn't off, was because when the sun shine on the screen I could actually see Google Maps.

Other than that it looks like it's off: I don't care for DAB+ because only reason I was using the FM-Radio today, is because I'm running out of mobile data. So I wanted to save my data.

Works great though native Google Maps on the headunit: now I understand why most people don't use AA anymore, once they discover the capabilities of their head-unit. My previous headunit was basically incapable of running Google Maps smoothly, hence I only used AA with that unit.

Still considering though to install HereWeGo for offline navigation: just to bad, the new version is worse than the old one which had real voices instead text to speech.
[FYT Android Head Units] Tweak-NL:
On my M300S i have a hardware button for volume. Pressing it indeed mutes the audio. Holding the button for 3 secs is doing nothing. (or i made a mistake)

On my old cheap android radio there was an option in the settings so i could change the brightness when i turn on the lights (canbus detection?) but on this one not sure where i can find it.

Today when i pressed the navi button the popup came again that i need to setup a default navi app. So again i picked google maps. Now i know why this is happening i think, 2 days ago google maps was updated. So after the update i think you need to set primary navi app i think?
[FYT Android Head Units] mohsan87:
At last found some detailed review. I am also planning to upgrade old PX5 with this M500S for my Suzuki Swift,

Could you please make a video of how Wired Android Auto Works on this unit ?

and does this M500S comes with IPS display or QLED Display? as seller at AliExpress offering upgrade from IPS to QLED in $20. Does it worth to upgrade to QLED ? both IPS and QLED have same resolution 1280*720 perhaps.
[FYT Android Head Units] DexterMorganNL:
Sorry I can't make a video: but wired Android works by using Car Link, you have to plug in your USB cable. Also you can set Car Link to open automatically when connecting a usb device.

In the specifications the display is labeled as IPS, with a resolution of 1280*720 indeed. Could be Qled? But I guess it's just IPS, as the specifications say. Personally I didn't care to upgrade to Qled, and I'm very satisfied with the IPS screen.
[FYT Android Head Units] mohsan87:
anything other thing to consider before I buy it ??
[FYT Android Head Units] DexterMorganNL:
In case of a Suzuki Swift not so much: I'm guessing you are having a standard Carradio now? And Suzuki don't use Canbus, so no need to take that in account either.

Just keep in mind, it might some tweaks and fixing bugs before it really works flawlessly.
[FYT Android Head Units] mohsan87:
yes, no CAN in Suzuki Swift, right now using KLYDE PX5, but its LCD making trouble. so want to upgrade to 10"
[FYT Android Head Units] DexterMorganNL:
I guess that shouldn't be an issue, it's all fairly straightforward. And this unit is really fast, even though I'm never going be using it to its fullest potential.
[FYT Android Head Units] DexterMorganNL:
Another suprise this morning: Here We Go Navigation kept crashing, so decided to remove it. That's a bit sad, as it one of the few navigation apps with offline maps. I'm staying in a B&B where my car can connected to WiFi, so I took the chance to download Spotify songs offline.

HERE WeGo: Maps & Navigation - Apps on Google Play

Enjoy the journey

play.google.com

And Android Auto wireless wasn't doing it job yesterday, connecting takes sometimes a bit. But usually that shouldn't be a problem. So I'm going try to wired connection.

It annoyed me anyway, because I was in a maze and totally lost my way while AA wasn't being connected. I stopped and used Google Maps straight from the headunit instead.

The thing with AA is, that it's layout is slightly better for in car use than native Google Maps. But Google Maps is working flawless as well, so I have been switching between them.

And the red part of the screen, I can basically only see for a part: as my steering wheel blocks that, depending the position of my hand. So Android Auto allows me to see the navigation directions clearly. Although it hasn't been a real issue.
[FYT Android Head Units] surfer63:
I thought that HereWeGo was now only for cities?

Anyway, I use Magic Earth for navigation. I consider it very good with good instructions and free traffic information, although it is not as good as the traffic info from Maps or TomTom. It is free with offline maps and doesn't share any information with anyone.
[FYT Android Head Units] DexterMorganNL:
No it isn't and it used to be a really good offline navigation app, until they decided to modernize it. Now it's not that good anymore and it doesn't even run without crashing.

Currently I'm trying Splitscreen with on the left Spotify, and on the right Google Maps. That gets me a similar result as Android Auto, which I like the layout. But I'm getting extremely annoyed with it crashing down frequently.

I tried it wired, and it crashed several times as well. The only benefit was, it would connect quickly again. But it has proven not to be reliable at all, because I don't want to restart Car Link all the time while driving.
[FYT Android Head Units] surfer63:
Like mentioned: I use Magic Earth and sometimes Google Maps. In splitscreen I only get Maps on the right side, not on the left side. With any other nav app I can put it left or right. I prefer left for better visibility, especially when the sun comes from the right or left and you get reflections.
[FYT Android Head Units] DexterMorganNL:
I have checked Magic Earth out on my phone, and it actually looks quite promising. Just I found the offline maps a bit big in file size, more than 1GB for the Netherlands. Lucky I bought 64GB version.

But up till now I'm satisfied with Google Maps: Android Auto is something, that I will forget. It annoys me to much that it crashes so often, without any obvious reason. Expect for the wireless....

Lucky they don't advertise it, on AliExpress only wired Android Auto is advertised and even that doesn't work as it should. Funny though on the Quad-Core it was working wired fine, so perhaps Google has messed up with their updates.
[FYT Android Head Units] marchnz:
Thanks @surfer63

NOt google messing up, these devices are not true AA
[FYT Android Head Units] DexterMorganNL:
I know that, but I read Android Auto itself is very buggy as well: people who have true AA in their cars, also experience all kind of issue's. The funny thing is, wireless worked better than wired.

The thing I particularly like about wireless AA, you don't need to mess around with USB cables. And you don't even need to take your phone out of your pocket, only before starting the headunit you should already start Google Maps on your phone.

Once the car is started, and Carlink finished connecting. Then automatically the route is displayed on your headunit, including autoplay of Spotify. I mean when it works it's great, but when it crashes during driving. Than its actually potential dangerous, as you need to close Carlink and restart it.

Only thing I don't really get, on my slow and not even capable of running native Google Maps smoothly. Android Auto was working better on that unit, as I didn't experience occasional crashes while connected to USB cable on that unit.

But other than that, on all other parts that Quad-Core unit wasn't very great. Only Android Auto was something, it did better: although displaying in a lower resolution.
[FYT Android Head Units] leo06:
Wireless carplay working fine. Considering switching to apple.😀😀
[FYT Android Head Units] DexterMorganNL:
If I win a lottery: I'm using a Xiaomi Mi 10T Lite as my smartphone, so a iPhone is out if the question. But actually the issue with disconnecting when the mobile network is changed, might be a bug within Xiaomi 's firmware.
[FYT Android Head Units] leo06:
It’s funny though that Apple CarPlay is working way better in android headunit
[FYT Android Head Units] DexterMorganNL:
Well they only have to support iPhone, and not 10.000 different kind of Android phones. So it's not very surprising that Carplay works flawlessly.
[FYT Android Head Units] marchnz:
But wack-a-mole as Apple and Google make changes and these Chinese origin headunits pseudo carplay/aa stops working.

Why anyone wants to do screen mirroring on full android is beyond me.

The OP posting about Google maps running in tablet mode is an easy fix - use another launcher or open maps from the apps screen.
[FYT Android Head Units] leo06:
I had a dongle for wireless carplay for the last 3 years from iphone x and now the iphone 12, always worked flawlessly. It's not screen mirroring, I am listening my music on the homepod then I leave my house I am starting my car and the music starts playing from where I left. I don't need extra sim for data, I don't need to open hotspot on my phone and the maps are easier for searching an address on my rather on the head unit. I can make or receive calls from the head units dislay, I can interact with Siri with yust saying hey Siri do that.
[FYT Android Head Units] DexterMorganNL:
Actually most people I know in real life, only use these head-units for running Android Auto. But the reason people wanna use it is easy to understand: it's convenient, when it works..... and no need to bother with starting your WiFi hotspot.

Especially wireless: set the route on your phone, put it away in your pocket. Open Carlink and it should connect automatically to your phone, and load Android Auto. But when it doesn't work, it's just frustrating.

I like the interface from Android Auto, which isn't available when running Google Maps native. Then I only have like a very small Spotify player, wherein AA it's a bit bigger.

But I like to switch between native Google Maps and AA: atleast I want to have the ability to choose. But yes changing the FrontApp, fixed the issue I had with native Google Maps in the beginning.

I found wired Android Auto not so convenient, so I won't be using that. It's very unlikely that Google or Apple will change the way AA/Carplay works, because all those cars aren't getting their software updated either.

So you would have a lot of angry car owners, if Google decided to stop supporting older units.
[FYT Android Head Units] surfer63:
Did anyone of you ever tried Head Unit Reloaded (HUR) in combination with AA or "Automate - Car Dashboard" directly on the unit?

I did try both, but as the direct unit gives me everything I want, I did not proceed with both solutions.
[FYT Android Head Units] DexterMorganNL:
So do both work? Because on Tweakers.net there was the discussion about Headunit Reloaded, but the developer of this app has stopped development. That makes me not wanna buy it.

The idea of having Android Auto directly on the headunit, without even having to use my phone: is quite nice. But the reviews of the app, show it's quite buggy.
[FYT Android Head Units] surfer63:
That's correct but that doesn't mean it is not good. Software that always needs new versions can also mean it is extremely buggy and when one bug is fixed, the next is introduced. There are so many apps that are now completely stable and mature that they don't need further development.

I used Automate only 2 days, but I prefer an "old fashioned" launcher that simply allows me to chose bigger icons for easy selection on bumpy roads (not that there are so many in the Netherlands).
[FYT Android Head Units] DexterMorganNL:
I just installed Automate on my phone: and I'm sure I wouldn't like it on my headunit either. It would be nice though if a head-unit interface for Google Maps would be available.

But I rather run it straight on the headunit, or use Android Auto: Google has put a lot of effort into developing this interface for use of cars. So something like Automate can't replace it.
[FYT Android Head Units] DexterMorganNL:
I still haven't fixed the interference in the reverse camera, but in the meanwhile I discovered some more settings.

https://xdaforums.com/t/interference-reverse-camera-celerio.4482459/

When disabling deep sleep, the unit will cold boot twice. This way the reverse camera didn't work at all: so now I have enabled a delay of switching off for three seconds. You can set it up to 10 mins delay.

This way it won't cold boot twice, when you start the unit first with ACC enabled.
[FYT Android Head Units] marchnz:
There is a issue with the wiring, headunit or camera. No amount of tweaks or software hacks will resolve it.
[FYT Android Head Units] farhanito:
Good day, hope this is the right place to ask.

I'm having hardware issue with Rear Left channel on my unit after a few months of use. When it's connected to the speaker, it causes all other speakers produce no sound. But when that Rear Left channel is disconnected, other speakers works fine. I've checked the speaker itself is still in good condition.

What could possibly be the problem? Faulty Amp chip?

Will an external DSP Amp (connected through digital optical cable) helps in my case? Though I'd ask first before getting one.

Thanks
[FYT Android Head Units] marchnz:
Is the device a uis7862 FYT device, post screenshot or details from Android system information including MCU version.
[FYT Android Head Units] DexterMorganNL:
Well yes I guess so, now I have ordered a step down dc to dc converter: so I can convert the 14v while the engine is on, to 12v because it's quite likely this is causing the interference. When the engine runs the voltage is about 14v and while it's off, about 12v.

€ 1,19 5%OFF | LM2596 BUCK 3A DC-DC Voltage Adjustable Step-Down Power Module + Blue LED Voltmeter

https://a.aliexpress.com/_EJwFcoF

But I wanna do some more troubleshooting, for example I also found a YouTube video claiming the double ground causes interference. So I will disconnect the ground cable from the car, to see what it does while this car camera filter is still connected.
[FYT Android Head Units] surfer63:
I am not a hardware technical guy so I can't explain it myself, but I read a post 1-1½ years back, where someone described that the 12V (or 14V for that matter) can also cause quite some interference. He built some very simple capacitor mini-circuit in between to fix it. But I can't find the post back.
[FYT Android Head Units] DexterMorganNL:
That kinds sounds like the Car Camera Filter that I ordered from AliExpress: that basically contains a capacitor inside.

Now I have disconnected the ground cable from the DC cable, because in another YouTube video a guy solved the interference like this. And I had it connected on a easy reachable place, so trying this out just cost me a min of my time.

This Car Camera Filter I'm keeping between the DC cable for now, because there are still options I haven't tried. But some I just find very unlikely, so I'm still troubleshooting and hope that disconnecting the ground cable might help.

Well that didn't help either, also with the Car Camera Filter the interference has changed. Before you could see black artifacts inside the screen, now it just looks warped. So the filter did change something, just didn't get rid of the interference.
[FYT Android Head Units] marchnz:
Has vehicle alternator been checked, 14v is too high
[FYT Android Head Units] DexterMorganNL:
No but the alternator should be fine: the voltage is always higher, when engine is running.

I got one of these as well, and use it to measure the voltage: it fluctuates between 14v and 15v actually, just once it reached 15v and the rest of the time it stay around 14.3v

A fellow Suzuki Celerio owner suggested, the interference might be high frequency interference. Which you can solve by placing a Ferrite ring, so I have ordered some of these as well.

These things you used to find very commonly on electronics: I remember having these Ferrite rings, on cables from game consoles. So I'm going place it closely to the RCA connector, near the headunit.

And the Car Camera Filter, that one has to be removed: it makes things even worse. But this going be a long project, because delivery from AliExpress tends to take up to month sometimes.
[FYT Android Head Units] marchnz:
AC noise wont be seen on a DC meter..... you will need ALOT of ferrite chokes on wire to mask a problem....a better way to mask the vehicle problem is place inductors in video supply stream, head unit and at camera.

or fix the problem.
[FYT Android Head Units] DexterMorganNL:
It's probably coming from high frequency, could be the spark plugs or whatever. For sure isn't my alternator.... I don't know where you get the idea, that the voltage in a car can't be 14v?

Hoogfrequent - Wikipedia

nl.wikipedia.org

So quite likely the interference isn't coming from the powersource, but from the engine or any kind of part of the car that is causing the RCA cable to pick up interference?

The idea is to place a ferrite ring just behind the RCA connection, at the headunit. Which hopefully should help, solve this interference.

Ferrite bead - Wikipedia

en.wikipedia.org

They are designed to suppress high-frequency electronic noise in electronic circuits. And considering they are relatively cheap, I have ordered two from our Chinese friends at AliExpress.

https://a.aliexpress.com/_EJiNW19

I just have to attach it to the cable, so no need to remove the headunit or so. This cable is reachable lucky. My hope is these Ferrite rings can solve the interference, because the Car Camera Filter didn't do it.

https://a.aliexpress.com/_EI4ZPPH

Actually I also think now, the DC to DC step down converter might not be needed or help. But I have ordered one anyway, because again it's dirt cheap. I just have to try all of these, because there isn't a solution that works for all vehicles.

The GreenYi seller suggested the Car Camera Filter, but I didn't have a high expectation of it. So bought one that took long to receive, but saved me some money.
[FYT Android Head Units] roti86:
@DexterMorganNL which size of ferrite ring have you ordered for the RCA cable? I have a Suzuki S-Cross with just a little bit of interference on the reverse image (my back camera is grounded on the reverse light wire directly, not on the connector). I think this may help for me as well, but I will wait for your review before ordering :)

Ps.: Nice review, I have been using Mekede M300s in my car since Apr, beside some small bugs it is working fine.
[FYT Android Head Units] DexterMorganNL:
I have ordered the 3.5mm, as the RCA cable isn't bigger than the. If I was you I would just order those already....

They are € 1,24 for two pieces and if you wait, until I received it: than you gotta wait quite sometime. Because shipping sometimes takes long, although I'm hoping they upgrade my shipping.

Because combined I order a totally of just over € 10 and than AliExpress, usually would collect your orders in a warehouse in China. And then send them in one package, with upgraded shipping ( usually AlliExpress Standard Shipping).

On the headunit I now have Carlink set to start automatically at bootup, because I have deep sleep disabled. And to be honest I'm finding it more convenient, to already set the route on my phone.

Start the car in one time, start driving and within half a minute Android Auto appears on my screen: no need to connect a USB cable, no need to touch the screen at start car link.

And I'm trying out AGAMA Car Launcher, seems to work good. But the main point actually is kinda: the stock Launcher, is a bit messed up with the Frontapp. So I just like to try something else, even though I wouldn't see it anyway for most off the time.
[FYT Android Head Units] surfer63:
The displayed app in the display area is the following property that is set by the launcher originally to:

persist.launcher.packagename=com.google.android.apps.maps

The frontapp changes this to the packagename you select.

So I assume that when you make a config.txt with this same google maps line,

or an empty line like "persist.launcher.packagename="

you can change the default behavior again

Edit: Don't confuse this one with the default navi app proprty being "persist.sys.navi.packagename"
[FYT Android Head Units] DexterMorganNL:
I don't know, but this FrontApp thingy is kinda messed-up, so I thought the solution would be to change it to any kind of app. And yes that works, but still limited.

For example when I have Spotify displayed inside there, than its impossible to use it for Splitscreen. But I'm not sure if I like AGAMA Car Launcher either. Just it's way better developed than the stock launchers.
[FYT Android Head Units] Solvin:
Try VIVID Car Launcher
[FYT Android Head Units] DexterMorganNL:
Tried it on the phone: I think I would find it to busy, and in the review's people report all kind of issue's. Actually I might consider using Nova Launcher, but for now I'm fine with AGAMA until the trial of 30 days finished.
[FYT Android Head Units] DexterMorganNL:
This headunit keeps surprising me: I have deep sleep switched off, so the time and date are sometimes wrong. Which was the case this morning..... so AGAMA Car Launcher refused to work. I have switched back to stock Launcher again. Basically it needs an internet connection to correct the time and date, or the wireless Android Auto would also correct it: as it's connected by WiFi.

Another annoying issue is Google Playstore: somehow apps aren't being updated and it stuck at "In behandeling" or in English in proces. Don't know what's the reason and after 10 mins or so, I decided to forget about it.

It worked again, and I let the unit do the updates while I removed the key from the car. By delaying the shutdown with 5 mins.
