Hi, I have this unit:
https://www.amazon.co.uk/gp/aw/d/B00P7G82TS/ref=ya_aw_oh_pii
The standard fm radio does not work, and I sometimes use tunein radio, but I don't always have a internet signal.
I'm thinking of buying a digital car aerial and installing that to use digital radio, does anyone know if this is possible? If so what is the best digital radio app?
Thanks
John

I have just installed this unit in my car. It is really great.
Android 6.0.1, 1024x600, 2gb ram...radio tda7786...
But...
Have some issues with fm radio. On frequencies where should be only one station i hear two. For example on 92.7, 103, 104.5 fm i hear proper station but in the backgound i can hear station from 101.7.
How to fix that?
I found radio settings... What for are fm local and dx numbers?
And the second qestion is... How to root that device?
I have this HU and my fm radio reception is very poor.
Already tried normal antenna and amplified antenna but nothing works.
When i try old radio its just fine.
Someone have a solution or another fm tuner offline app.
Its an android 8.1(go) system so i cant download any apps on usb or sd because it can t find the files.
I've had 3 Chinese head units already (on different cars) and they all seem to have this problem

Hello,
I have just bought a Ossuret JGQTR92P car radio on ebay.
Radio is useless, as picks up very few channels, I was going to try and install amplified aerial to see if helps, radio app is not very good, was hoping someone had a better radio app with RDS that I could install ?.
But mainly I was looking for firmware updates etc to try and make interface a lot better. Does anyone own one of these or is aware of where to obtain the latest firmware ?
Thank you
I was looking for a different radio app, since the built-in one isn't very good and does not store stations persistently. I downloaded NextRadio, but when it loads it says "FM Radio is Unavailable...... NextRadio doesn't have access to the FM radio receiver in your device". How is it that the stock Radio app works but not this one? Anyone have a good radio app that uses the FM tuner? (Not internet radio). Thanks.

The radio chip in these units is not presented to the Android system. Instead the radio app sends commands to a dedicated radio module on the amplifier board. The same for the Bluetooth unit, as it's not actually part of the Android tablet.
These head units are two devices that work together. The Android part is basically a tablet that has dedicated apps to talk to the Radio part. The two parts work separate, and that's why all the FM radio apps and stuff are such garbage. They have to send commands to the actual FM module on the Radio board and get back a response about what is happening. In theory it would be possible to see what commands and data the FM radio app uses and write your own to send & receive the same data.

Is this separation of modules also related to why the EQ/Balance/Fade functionality does not work on this head unit? I noticed a few reports stating the same problem I'm having... where the faders have no effect whatsoever. No front/rear fade, no left/right pan, and no EQ change.

By the way, I discovered something today... I was playing music files from a USB drive and lo and behold, the EQ and Balance functionality worked. I started to think about why and I think it has to do with what you said. The reason it wasn't working for me initially is because I was trying to use it with the radio, and since u said the radio is outside of the android layer, that's probably why it wasn't working. But it looks like it DOES work with any audio that's within the Android layer.
Can confirm what @pizzaboy192 has posted. You will NOT be able to use any sound processing, not even to mute radio during navigation directions because of this funky implementation.
All you can do is root and then replace the radio apk with the macnaughty one that does save stations and (for me) has HD information.

BTW :you probably miss the HIFI flag in build.prop as in my case at least the built in equalizer and spatializer work with the radio app.. Viper4Android however, does not work, despite being complied in and having root access, simply because the audio path from the radio bypasses the OS.
With OEM head unit the reception is fine. With the PX6 head unit the FM reception is quite poor. I have checked that the OEM amplifier gets power. I have tried one of those small "FM amplifiers" but it just made it worse.
So I am thinking about getting an external antenna like this one:
Eightwood DAB/DAB+ Antenna Car Radio Antenna Splitter: Amazon.de: Elektronik
Eightwood DAB/DAB+ Antenna Car Radio Antenna Splitter: Amazon.de: Elektronik
www.amazon.de
They seem to get good reviews at Amazon but I am curious to hear if anyone here been using it with a Chinese Android head unit and if it made any difference?
Thanks!
I use one on a Joying HU, It works great. FM is perfect, GPS is also spot on. DAB worked on my last HU but, I needed a new DAB box for this HU, so I didn't bother. The bit rate for DAB in the UK is shocking, streaming is the way forward for good sound quality.
I’ve had one before and dab and fm radio worked perfect.
You should be able to get the oem aerial working properly though with this unit.
Have you got an adaptor for the antenna to go into the new unit or does the oem antenna cable just plug straight into the new unit?
The fm amplifier that you bought will make it worse because the chances are that your car will already have a factory fm amplifier.

Yes, I have an adaptor for the antenna, from Fakra to DIN. I have tried to disconnect power to the OEM amplifier, and then I got almost no reception at all, so I guess the amplifier works.
But I have realized that DAB+ sound quality isn't very good, so now I am hasitating to buy an external antenna. And just stream music and radio from apps.
If you get a good external antenna the sound will be better on dab. I use dab all the time.
It’s one of these that you need to get your FM working properly with your factory antenna https://www.ebay.co.uk/itm/353322093865 you connect the blue cable to the blue cable that comes out of the back of the headunit and it powers your factory antenna(although you should have got one of these with the headunit).
I bought similar antenna https://www.amazon.de/gp/product/B073R8KW7F to try to get better reception of DAB+ (instead of windscreen-sticked antenna), and for DAB it made so much better reception, so i have now DAB+ reception even in my underground parking place %) Cannot say though about FM - i had no problems with OEM antenna before, and new antenna didn't make FM reception better. But as i don't use FM anymore (DAB+ converage in my area is good, and with new antenna i don't have reception problems in other areas either, all FM stations i was interested before, are available over DAB), i compared audio quality DAB+ <-> online radios. Yes, the quality of online services is mostly better, but:
1. while driving, with all exterior sounds (tire noise, air whizzing @ high speeds, noise form other cars), i barely hear the difference.
2. hearing online radio with e.g 128kbps, will eat ~60 MB per hour. If it is OK for you - ignore it.
3. The 3G/4G coverage (at least here, in Germany), isn't perfect - i had already 3-10 minutes of "no internet" while driving, but, surprisingly, DAB was available there.
4. with proper DAB+ software you will get additional services, like possibility of radio recording, or timeshifting (personally me use it often while hearing some news and got distracted with road traffic).
So, after using similar antenna (same manufacturer, but with aerial rod) during last year, i have never had problems with DAB receiving (neither with FM, but i had no problems with FM reception with OEM antenna either).
