I own Junsun Android radio with standard I would say pinout on the back. Noticed that there is a pin for external WIFI antenna.
Has anyone tried this pin and installed external WIFI antenna?

that is great, I was just going to post it, realized this last night.
The question I have: how do you connect commercial antenna with two part ( main conductor and shielding ) to this one wire?
@wotii098
should I solder the blue cable to the center pin of the WIFI antenna?.
should the shielding be connected to the pin 9 ( GND ) ?
I didnt connect(or solder) antything to these wires. I just use them as they are and I can't complain about wifi/BT range.

Probably. I once had to rewire a DVR built into a cabin mirror - it wanted to see +5v on its MicroUSB jack and I already had +12v on the barrel plug that I had rewired for another DVR previously and I didn't feel like wiring any more cables into the car. Since I needed to drop +12v down to +5v I opened up the mirror and soldered in an LM7805 voltage regulator in a TO220 case. Lo and behold, w/o a heat sink once the VR started heating up the LCD would go fuzzy, show coloured stripes and eventually crash.
I desoldered the VR from the PCB and soldered in a DC-DC converter instead. These converters consume very little current and can be had for around a buck a piece on ebay from China. No problems with the LCD since then. HTH.
Could be lose wire in the unit. Mine does that, but usually doesn't crash. Is the screen too hot to touch? Mine will get that hot and still work.
You ever wondered why you have a poor DAB signal?
Maybe you're using such an USB charger from hell:

I had suddenly a poor DAB signal. But not just no signal. Depending on the places I drove, DAB reception was terrible. Lots of dropouts but depending on the location I thought it was the antenna or the USB DAB box. Sometimes DAB signal was perfect and signal status indicator was dark green.
Then I removed the USB car charger. And what should I say? Perfect reception and it is again a pleasure to listen to the radio. So the interference is only a problem if the DAB signal is not 150% which makes it difficult to identify the root cause.
I have researched and there are many people who have identified a troublesome USB charger. These devices from hell are even poison for OEM head units of high-end brands like Mercedes any BMW.
Since I have not found any information in this forum, I would like to share these finding with you.
Stay healthy and drive carefully!

You should have the right connector to your head unit, mostly provided with ISO connectors for Power and speaker.
There you need an adapter from ISO to Quadlock. Search for your car... BTW: for VW you also need a CAN adapter to get clamp 15 and SWC working.
If you don´t have anything... Get in contact with the seller, ask for the right adapter cable or send this thing back.

Hello folks. I have a very big problem and I am infinitely sad about my new radio.
The following problem, I installed the junsun v1 pro in my BMW E91 and installed a reversing camera which is located in the recessed grip.
But the pin on the radio itself with the 10-pin pin from the video chinch with the black cable (red and black on the video chinch) broke off because there was too much voltage on it. was my fault
How can I fix this pin in the radio or is there an alternative to connecting the camera via chinch without having to use the pin or another slot on the radio so that it still works? An adapter maybe?
It would be so nice if maybe someone could help me or has a tip? I'm really desperate.
Hello. Please. Help me!!!
Get a new pin and crimp it on the wire, put it back in.

Thanks for the answer.
Aja and then insert this pin from the outside through the plug, you mean? It works like this?
There is no other slot on this radio?
There are two more slots above this slot with the camera.
What are these for?
My picture is there at the beginning but it flickers or disappears shortly thereafter when I drive. I soldered a pin but I'm not sure if it's okay or if the wiring is causing me a problem.
Hi,
I just unboxed the Head Unit for my Ford Focus MK2 and found that the wiring does not look like the very simple diagram on the sellers page.
Going from the can bus connector there are 2 wires to a white plug. One wire is green/white and one wire is white/green. I am in doubt where to connect this plug.
Further, from the can bus there are two wires going to the head unit. Its a red wire and an orange wire. The wires are split and connects to a plug. From the plug that is supposed to connecting to the car there is a socket with a red and orange wire. I am in doubt what happens wether connecting or not.
There is also an orange/brown wire marked Key2
Maybe photo explains better:

They you may answer your questions here, to help other users.
Thank you.
It need to go in the free slot in the Head Unit but it is not shown on sellers page. There is only one slot that fits so its quite simple when you know.
