Hi Guys,
I recently bought an Erisin ES9162B.
The car is BMW E46 Facelift and had the original navigation in it, so I had to buy an extension cable that goes from the trunk to the central console.
When I connected everything, the head unit does not find all FM station. It finds the national ones, but I have to manually stop on an FM station if I want it to play. However, the reception goes wild when I start driving - every 2 secs, I am loosing the reception to the radio, which leads me to believe there is a problem with the antenna.
Could someone point me on what the problem might be?
As per the attached file, I have connected only 1 USB (23), big cables (17), FM antenna (20), GPS antenna (18) and Wi-Fi antenna (19).
I have read that there might be a loose connection and I have to open up the head unit, but please someone tell me whether I have to connect something else first, because I do not want to open up the unit itself yet. It's still new :crying:

Hi.
My Skoda Superb has navigation from factory, including GPS antenna on the roof. Does anyone know if this antenna will work with an Android head unit (Joying)? I need an adapter from FAKRA to SMA to physically connect it, but I don't know if the antenna would be compatible with regards to voltage, impedance etc.
The built in antennas has normally power fed to it. You need to verify it still has power or utilize
the antenna power from the HU. Else it should work. I've Hyundai factory antenna that I'm using.
Adapters are available everywhere. I bought mine from Aliexpress.

Ok, I've got antenna power for the radio antenna from the HU, but I don't know if it's needed for the GPS antenna as well. I will try and connect it with a passive adapter and see if it works.
Seems to work with just an adapter. I'm getting around the same signal levels as with the included antenna mounted outside the car.
Apologize if this is the wrong forum to post this in, but I just installed an Android 8.1 head unit in my car in the USA, and I get great FM reception, but I can't get reception for any AM stations. I disconnected the unit and reconnected my old radio to make sure nothing had changed in the car, and I still got good FM and AM with the old radio, so I know the antenna is good.
Is there a setting in the radio for region (USA, Europe, China, etc) that could affect this? When I scan stations, it seems to be in the right range of frequencies, but doesn't stop on any, and I can't manually force it to a station that I know (950). Instead I can make it go to either 945 or 954. I have searched through all of the menus that I can find, and can't find anything that would allow me to see or change the region.
Thanks in advance - Paul
Update on this issue - I was able to get to the menu to change the radio region:
Car Settings:: About the Device (passcode 8888):: Radio
It was defaulted to Europe - I changed it to America 1 and America 2 which at least allowed me to directly tune to a couple of strong AM stations that I know, but I still had no reception. Everything else about the unit works well. I am trying to get them to send me a replacement thinking it is something in the hardware, but please let me know if anyone has any other ideas on things to check.
I have this problem too. Great FM reception, VERY poor AM reception. I've tried all country codes (Australia is not available). I've asked vendor for a solution. Still waiting.
Did you get a solution?
I had this too until I realized that my car has a built in car antenna amplifier (most cars now do) and it needs to be powered. Without power to it, you'll barely get reception. So I connected the antenna amplifier to the powered antenna output from the head unit and that improved it some, but still it wasn't great. Then I checked the voltage from that wire I found that the head unit only puts out 10.6 volts instead of the required 12. So I hooked the power antenna to the same 12V power coming from the car that feeds the head unit and presto, now I get normal radio reception like I used to.
This constantly amazes me, why do so many people not understand about the aerial amplifiers used on most cars now? When you swap out a manufacturer specific unit, make sure all the wires are connected, they're there for a reason!
yes, but most people don't realize that the lead from the head unit that says ANTENNA is not suitable to power the antenna. You must use the 12V power supply coming from the car to power the antenna amp.
It varies with the head unit, many do put out the full battery voltage on the antenna feed wire (ours does) but obviously some don't, your fix is correct for those that don't. The issue is that everyone seems to just leave the amplifier wire disconnected and wonder why it doesn't work.

I know this is an old post but I'm having this issue.
I'm actually little confused as to how to remedy this.
Any help would be appreciated.
Should I splice the blue ant wire into the power wire going to the radio?
I was under the impression the blue ant wire was for people who had a power antenna that raises and lowers when the radio is powered on.
Here's the radio I got for a 2005 Corolla.

The ANT wire of the head unit is intended as power supply for the car antenna. Not only the automatic extending antennas need a power supply, also active antennas.
So it depends on your installed antenna if you need to connect it.
Some active antennas doesn't have a separate wire for power supply. In this case you need a "Phantomeinspeiseadapter" (Google it). Espacially cars from VW group (Skoda, Seat, VW, Audi...) need such an adapter in combination with a 3rd party radio.
The idea is to power the antenna only if it's needed (your listening to radio).
Alternatively the antenna could get its power from the ACC wire. In this case the antenna gets power as soon as you turn on the ignition.
The B+ wire should never be used to power the antenna because this would drain your cars battery 24/7.
Hi guys, I have a Android head unit called TS-4G and drive an Opel insignia. (This one https://a.aliexpress.com/_vdJ8NX ) - how can a find out which hardware platform it is?! I think it’s very similar to the px5
I replace the original radio with the Android one, but the radio signal is worst. Dump sound, no signal, no AF. I put a amplifier between the radio and my two car antennas, connected over fakra connectors. The amplifier is powered up with 12v (phantom) with amp I have very low signal, without nothing, so I decided to put my Orginal Radio back in. Now i look why is the signal so bad. I opened the Android head unit and check the reciever. There is a 7786AF-6 build in. Now is the question, replace it with a 6686 or not... ?! Or, how can i improve the signal strength.
Btw. gps, canbus, steeringwheel remote, LTE works nice. Only the fm tuner sucks...
Here some informations about this head unit

Exactly same unit here. Cause bad fm/am signal receiption I gave up and installed a dab+ dongle with new active shark roof antenna. It supports GPS, FM/AM and DAB+ . GPS, FM/AM has good signal receiption now, but DAB is not working well. There are some device interferences, too and I have to check the cables at back side again.
Btw, the PX5 headunit was much better.... (I've got an accident with my opel astra h )
I have a dab+ usb module too, but with a window antenna. In my location in middle germany i have with this antenna worst signal too. 100 meters good signal, next 100 no signal...
How you replace the orginal shark antenna? The orginal shark is in my case the gps one. How you connect gps, and fm with this one antenna? New cables to the antenna, or can use the old one?

some parts in the trunk that can prevent the roof lining from lowering must be removed. otherwise it is almost impossible to access and loosen the screw on the antenna. it's a very fiddly business, I couldn't loosen the screw on my antenna on my own and had to go to a workshop (and I really do a lot on cars.)
The original gps cable can be used again with the new antenna, for fm / am and dab a new separate cable must be pulled forward to the glove compartment. adapters may be required on the radio and dab module.
all in all, it is quite doable, but takes a lot of time. the biggest problem is loosening the old antenna and ensuring that there are no kinks in the roof lining. and make sure to disconnect the battery before converting.
But, it is possible to change the hardware (7786 to 6686 tuner?) the 2nd one is an digital fm tuner - pin out and size are the same. I read on some another threads, that ppl swap these fm tuners...
New firmware?

Hello,
i have the same unit on my opel insignia but i don't have the climate controls at the bottom. How did you put them?
Also I can't find the password for developer options
thank you
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).
Is there a difference in signal quality in these window antennas? I am wondering if swapping the one i have now will boost signal?
My original car radio only had FM which worked flawless. Since upgrading to the android head-unit…FM is impossible to listen, strange as it uses the same car antenna to connect into it?
I opted to buy a DAB+ antenna as the head unit will accept one but this is not great either. Any ideas?
You may have an active antenna on your cars roof and missed to connect the power supply.
I only have bad experience with the DAB windows antennas so I was forced to replace the existing antenna.
