joying gps has hard time to lock on

After getting a new antenna from joying I was still seeing only mid 30snr on 8 or so satellites. It constantly lost gps. All of my 4.4.4 units went through the dash and still had a good signal. 5.1.1 has known gps problems that will never be fixed as google moved on to android 6-7.
ACCURACY_THRES=0 in gps.conf fixed it more or less. The default value is about 40-42, but I never get that good of signal. Now It actually knows where I am going.

did you car already have GPS? my Jeep did, I bought an adapter that allows me to re-use the existing Jeep GPS with the Joying:

Pixel 2 XL Plus Pie Means Wifi Hot Spot Does Not Work With VW UK Carnet

Hi, has any one else had problems since the new ROM release of Vw car net (Discover Media in a Golf 7.5) connecting to the phones hot spot and still not able to get to the internet ?
Worked fine before pie and still works fine with iOS so o believe there is some thing odd going on.
IP seems to be allocated but it's almost as though gateway or DNS info is not been passed but I can't confirm.
Tested as is with a PC and it works fine.
Head unit has got the latest software now and finally I even switched to 3g which is another trick I have seen on ee phones

[PX3] Wifi stopped working - no connection

Hi,
i own a Xtrons PX3 with Android 7.1.2.
A couple months ago i noticed connection failures on my wifi. Over the following weeks the problem got worse. Today the device is completly unable to even find access points. Bluetooth is working perfectly.
I tried the following steps:
- multiple switching off and on again of wife: "activating wifi" taked about a minute. No access points. Wifi disables itself and turns on without finding networks.
- activating the access point: no effect
- replaced the antenna: no effect
- reseted network settings:
The wifi worked for one time 3 minutes. I was able to connect to my mobile phones access point. But after about 3 minutes the same error again. No networks. No connection at all.
- upgraded the MCU from MTCD_GS_V2.56_3 to MTCD_GS_2.94: no effect
- installed Malaysk 5.0 from https://forum.xda-developers.com/an...nt/rom-malaysk-roms-mtcd-mtce-device-t3693509 without data wipe: no effect
- installed Malaysk 5.0 WITH complete data wipe:
Again the wifi worked one time for 3 minutes. But now no wifi whatsoever.
I dont think it is a hardware issue. Otherwise it shouldnt have worked for some minuted after the complete data wipe.
Please help me. The Head Unit is more or less worthless without an internet connection.
Kind Regards

Hi there. I can assure you that it’s a hardware issue. I had this before and I replaced the WiFi and Bluetooth board and all was good after that.
The symptoms are exactly the same. Works for a moment but not always and for a very short time. This can happen because the chip gets quite hot and the soldering or the chip itself gets damaged.
My advice is to get a compatible board from China, they are very cheap - 2-3$ and replace it. I’ve done this twice now and both Bluetooth and WiFi are working well. I know how it behaves before failing.

Well, thanks. I thought if Bluetooth is working then it should Not be a Hardware issue. Because both things are handeled by the same Module.
Do you have a link or something for me where I can buy such a replacement part? I tried Google and eBay. No success.
Thx.
Kind regards
Hagen

Try AliExpress. I don’t know what kind of chip you have now to be able to advise.
The Bluetooth and WiFi can be on the same chip but the connections are different pins.
It might be a good idea before ordering and waiting to try and repeat the soldering points to the board.

WiFi Connection Problems

Hi all
I’ve recently bought a BMW E38 and it came with an android head unit. I’ve tried to connect to my iPhone to use it as a hotspot and it connects but only for a few seconds. Radios not working either but I think it’s not been fitted correctly.
I’ve tried researching online but can’t see any solutions. Really appreciate any help.
The details:
Model- PX5 (1024x600)
Android 8
MCU- MTCE_GS_V2.78_3
CPU- 8 core 64bit CPU coretex a53 @ 1.5g

What did the reseller suggest and has that been tried with anything else?

I had similar issue where HU's wifi turns off automatically after few seconds. Is your HU doing the same?

WiFi problems
I also have the same issue WiFi will either connect and disconnect repeatedly, or will just not find my network at all?? Either 4g dongle or tethered to iPhone. Although my phone will find the single and connect so I know they work so it must be something to do with the HU it’s nearly new running android 8.1. So far I’m stumped with finding a solution.

mine turned out to be the antenna problem. If I take off the small wifi antenna then wifi stays connected. this has reduced the wifi range considerably. I know it sucks but only thing that has worked for me so far.

Yeah I’ve had the same issues with my unit, I find sometimes it stays connected if I power up the iPhone hotspot a few seconds before powering up the head unit. If I forget and the head unit powers on first usually it refuses to obtain an IP from the phone.

Question Navifly 7862 6/128g QLED, gps signal reception problems

Hi, I bought the device in question for my Dacia Duster about eight months ago and I was fully satisfied, but for about a month I have had serious GPS reception problems. Initially, when I left the car from the garage, the GPS did not want to lock in the satellites and only started to work again when the car was restarted after a stop outdoors.
Now the problem has gotten worse, it seems that it doesn't want to know how to work anymore. I've tried everything from rebooting the device to clearing the cache of some apps (maps, Google play service, etc), but nothing seems to work.
Obviously we are talking about the original GPS receiver of the Dacia Duster which until a month ago was working very well.
Can you help me solve the problem?
Thank you.

Have you checked the connections to the unit? They might have gotten loose or something.
My car didn't have an original GPS antenna, so I used the one which came with the unit. Still works perfectly fine, and locks in in a few seconds even from a cold boot.

Yes, that was the first thing I checked and the connection is solid. Do you think maybe the GPS antenna needs to be replaced? If so, which one do you recommend?
Thanks.

I checked the listing on Aliexpress (https://www.aliexpress.com/i/1005002504629224.html). According to this, you should have a GPS antenna included with the unit.
This looks like it fits your unit and fairly cheap too: https://www.aliexpress.com/item/1005002061606837.html

I had the same issue with my unit - similar NaviFly 7862 unit - and its GPS. Just stopped working all of a sudden. After disconnecting it from the unit (and pulling out the unit to check for loosened wires and disable the internal mic while at it) everything seemed Ok so I put it back. Started working again and keeps working since.

In settings on the headunit, there is an option to look at the number of GPS satellites that have linked. Try change a few settings for GPS and see if you get different results on the number of connected satellites.

Thank you all, tomorrow I will install the original GPS antenna that arrived in the Navifly box. So far I had connected that stock of my car (Dacia Duster), may it be that it is not suitable and that this causes it to run intermittently?

I have looked at that setting many times, unfortunately when the Navifly is not receiving any satellite there is not much to do.

While there is an app to view satellites, There are no settings for GPS. Is your post a guess.

What I mean is that when the Navifly "decides" it does not want to receive satellites, the few options in the GPS settings make no difference.
Anyway, today I replaced my car's GPS antenna with the one I received along with the Navifly. I will have to test its operation over time also because a couple of days ago the Navifly GPS had "decided" to resume receiving satellites.
