GSM Antenna socket identification - P3600 General

Does anyone know what the production name is for the Antenna socket is on the Trinity?
It is the same on lots of models incl Blue Angel.
A supplier thought it might be a Miniture MX but couldn't be sure.
I want to see if it is possible to make a in-car holder with an external antenna connector.
Thanks in Advance

Extending wifi antenna

Having a hard time getting a good wifi signal. Anyone have any tips, suggestions, or ways to extend the wifi antenna?
I know someone wired it to a SMA port on the back with a normally stubby wifi antenna back there.
I toyed with this idea and was tempted to solder in the BNC jack/antenna off the spare router that I keep around just in case but eventually had to scrap it due to the limited RE in the dashboard cavity behind the HU. I used a slightly different approach which has proven to be just as effective: http://forum.xda-developers.com/showpost.php?p=67394021&postcount=2
I did it here on my old Android 4 unit:
http://forum.xda-developers.com/and...rk3188-rk3066-2-din-head-units-t3193170/page2
And i did the same thing on my Android 5.5.1 unit as well.
What I do is cut off the end of the cable they provide. All the provide is a simple antenna made from cutting the coax back a bit to expose some center conductor, and the put some heat shrink on it.
I cut that off, and actually crimp on a proper rp-sma jack and mount it to the case. It's not difficult, but I am a ham radio operator, and have the correct crimping tools and experience doing it.
I do it on mine because I actually have a wifi antenna externally mounted on my jeep, and I need the rp-sma jack to connect to the coax from that outside antenna.
On the new Android 5.5.1 unit, it has TWO wifi antennas, I guess for diversity reception which can sometimes help the signals. But what I did was leave with the short stock antenna, and only put the connector on the other which goes to the external antenna. So now I sort of have one internal antenna, and one external.

in that post, you linked to an external antenna on ebay. did you end up buying that and is it good? or were you just thinking about it? in this post you mention an external antenna mounted on your jeep. is that the ebay antenna you linked or a different one?
my unit has a weak antenna on its back side outside of the box. it's fine for picking up my phone when i make it a hotspot in the car but doesn't/can't pick up wifi from the house when i am parked in the garage. phone easily picks it up. i don't know if it's just a weak antenna or the fact that it's surrounded by the dashboard housing... or both. would like to change that if i can do it on the cheap.

MCTD unit poor radio reception in UK

Recently got an MCTD unit, has a v3 mainboard and I am suffering on poor FM reception and non existent AM (not bothered about AM though)
Have read that sometimes the aerials are not connected internally so had a look, one of the earth points was a bit suspect so re-soldered that, but no improvement. If I am stationary I can get 3 stations, however when I start to move I lose the signal. Interestingly it does seem to improve if I leave the radio out (I.e. Not fixed into position in the car).
I think the unit is an A Media (will have to check later) but it is a Huefei variant (running Android 5.1.1)
I have bought replacement internal aerial adaptors that are boosted to no real improvement (although after doing a bit more reading I need to check if the booster power source (from the ANT wire from the headunit) is actually giving 12V
Any ideas / mods to help improve it? Aerial works fine with standard headunit.
Thanks
anyone any ideas?
ok if anyone is interested, I bought a cheap window aerial that has a power booster, can now get channels but still not great. My next step is to either replace the roof aerial on my car (or certainly the wiring), of take of the power boosting element from the new aerial and incorporate that into the car roof mount
Buy this (don't look to the price) and you will say thanks to me for long time

I am not interested in making publicity of this product but even I would have been you will be as happy as I am. BEST!!!
You will need extra wire extenders as the product has short cables fitted. It's on that page the link of what you will need.
similar issue
Hi are you still having this issue or did you manage to fix it? if so what did you do please?
i am having a similar issue with mine and found that iv improved things by putting a cable to earth my head unit (cable from screw on back to ground on loom) and also i have changed the cable coming from the Headunit with one from halfords (at first glance i thought it was part of the unit as it had the black sheath and blue cable but it just pulls out)
not fully, I am going to look at the antenna wire from the headunit as I dont have that connected and that may help (from reading the pumpkin website).
I have good earths which I have measured with a multimeter so I know thats good.
If I cant imrove then I will look at an aerial from the above place
htt p:// www .ha lfords .co m/ techno logy/ car-audio/ stereo-fitting-acce ssories /aut oleads-pc5-111-fakra-to-din-aerial-adaptor
i used that cable from halfords to replace the one that came with the headunit. For me it was problem solved. obviously the one that came with it wasnt making a good enough contact.
sorry had to put spaces as im not allowed to put links yet.
Thanks for the link but I have about 3 different ones and they all make good contact (have checked with the unit taken apart and everything makes contact where it should)
I am going to check my installed aerial to see if I can work out whats going on with that. I can ge radio 2 now fully on my way to work (50miles each way) but I dont want to listen to radio 2
It is antenna wiring issue, not antenna itself.
I had the same problem in US with my A-Media unit. Initially the seller sent me a power cable and I had poor radio reception, FM working but not great, no AM at all. When the seller figured out wrong cable for steering wheel issues he sent me the correct cable and everything works great including radio FM/AM. My antenna harness has two wires but the first cable connected only one. The 2nd cable has both antenna wires connected, one to antenna socket and the other goes to power cable connector.
Sorted it out, the existing aerial on my car was a dummy aerial (sharkfin), turns out the aerial itself is on the rear windscreen.
Anyway, I got an DAB aerial off ebay (bee sting type) fitted that in place of the sharkfin and re wired it. Result now have perfect reception on both FM and DAB with no loss of signal at all. Only cost £29.99 GBP as well with all wiring extensions etc

hello, i have the same problem with my unit.
i wanna buy that antenna also on ebay. but the (bee sting type) you told about have a din style connector.
the original one that was by the radio is a usb type. how did you fix that problem?
I was able to solve my unworking AM Radio here.

Replacing 2014 Corolla S head unit

I'm in the market for an android head unit. The OEM one in my car is now not working and Toyota wants an arm and a leg for a new one. Instead of just buying an OEM one off EBay. I wanted to buy an Android one. Any suggestions? Also I had a few questions.
I had GPS in my car, so do I need to still use the external GPS antenna?
I have the same question for the microphone. Less wired the better.
Thanks!

1. I used the one that came with the replacement HU, but you could try an fakra adapter. If you dont know what that is, best use GPS antenna that comes with replacement; concealed under dash should be sufficient .
2. Yes, if you are skilled or have access to a skilled electronics tech. No adapter exists. Starts with reverse engineering from toyota electrical wiring diagram.
For my 2010 Blade (corolla hatch with 3.5l v6) I made an interface for the oem MIC and used the GPS that came with the new MTCD JY.
Anyone have an idea what port #8 in this picture is? There was an adapter that has a male usb end and I'm not sure if I'm supposed to plug it in anywhere?

How to convert generic GPS to work with shadow GT-580w dashcam?

I have a Shadow GT-580W Dashcam that has a GPS port. The GPS antenna that is sold for the unit can be seen here: https://www.amazon.com/global-positioning-system-supports-camera/dp/B01M26K3WW
The port for the antenna seems to be configured like a standard audio input (i.e. a headphone port) and is powered with +3.29v on the tip and ground on ground.
I want to make my own GPS antenna for it. I purchased an active antenna off Ebay https://www.ebay.com/itm/Universal-...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 . I snipped the connector off, then soldered the center wire to the audio tip tab and the ground to the ground tab. I then plugged it into my dashcam and saw that it was getting the 3.29v to the antenna. My problem is the dashcam searches for the GPS signal but doesn't find it after about 10 minutes.
The antenna I bought runs on 2.7-5v and has a frequency of 1575.42MHZ.
Is there something I'm missing?
Should I reverse the + and ground?
Did I get the wrong antenna? etc...
Any ideas are welcome

What GPS antennas do these units use ?

Does anyone know what type of GPS antenna's these units use?
I have an Xtrons PX5 Oreo head unit, but I'm having difficulty positioning the GPS antenna in a good location, due to lack of space under the dashboard.
I'd like to buy another antenna, to take apart and get rid of the plastic cover, in the hope that it will be a bit smaller and I can squeeze it under the dash
However I'm not sure if all antennas that I can buy are the same.
The socket type on the back of the Xtrons unit appears to be a type called FAKRA, and the antenna that came with the unit has a right angle connector.
I can find loads of similar looking antennas on eBay and AliExpress etc, with FAKRA plugs, but most of them are straight (so I'll need to check if a longer plug would be a problem.)
But apart from that... Does anyone know if there is anything specific I need to look out for when buying another GPS antenna ?
Some antennas say they are "Active" and are powered by between 3 and 5V, but I presume they are all like this ?
Also, I've seen splitter cables, which would suggest that I could install more than one GPS antenna, but I'm not really sure if thats possible either ??
Thanks

What for a car do you have? (brand & model)
Xtrons TE706PL. It has a FAKRA connector on the back.
Since I posted, I've ordered a generic GPS antenna from AliExpress which has a FAKRA connector on it, (for less than $10)...
So I'll see if that works.
What I don't know however if these antennas are Passive or Active. I presume they are mostly Active, where between 3 and 5 volts is supplied to the antenna, via the same cable (coax) where the signals are sent into the unit (capacitive coupling)
As GPS signals are at 1500Mhz, the loss on thin coax is extreme, so I'd be surprised if any of these antennas, which come with several metres of coax, are passive.
(But I could be wrong.. In which case I'll probably also try to shorten the coax to just the length I need, as that will also improve GPS reception)

What was your determination on this. Does the radio use an active antenna or passive?
btw, its an active antenna. I bought a replacement antenna from anywhere they sell active gps antennas.
