Fix low compass accuracy on Google Maps - Android Head-Units

Hello, friends I have a android head unit, from Ekiy, android 10 and is having issues with the compass.
How I can calibrate it, because as Google says it's not possible.
Any ideas?

Where is the GPS antenna mounted?
You need to make sure that no metal is above the antenna and your wind shield should not have a metal vaporized sun protecting.
Search for an app called GPS Test in the store and do the AGPS update, which connects new to the available satellites and refreshes the GPS data.

Why do you think you would be able to calibrate you head unit???

Why inside of a metal door? Sorry, but you need a metal-free view to the sky, on top of the dash as example.
Exception is a metal vaporized wind shield...
GPS test shows an accuracy of 5m, so nearly perfect. Just the reception of the satellites is a bit poor, so change the position of your GPS antenna.

why does it take so long to get gps-signal?

hey guys,
i have a little question,
i just bought a haicom gps receiver and use tomtom 2 software. When i get out of my garage, it takes always more than 15 minutes to get a signal. sometimes during driving i also lose it. How comes?
when i connect my device to the receiver and power, i get something like "connecting to t-mobile MMS"...
oh, btw i have a MDA II with latest NL t-mobile rom. 1.60....
if anyone could help please...
thanks!
The gps should only take this long when first used, after that it should lock in a matter of a couple of minutes, to test the gps properly it is best to test it outside the vehicle, I think most Haicom mouse gps come with magnetic base so stick it on the roof and drive around, if it works better it is probably becuase your car has a metallised windscreen which blocks the signal. The message about connecting to the service provider is an error due to the com port being accessed i think, mine used to bring up activesync every time but once I canged my activesync settings on the xda to manual instead of auto sync it solved the problem.
so i should always drive around with my window open?? and stick the receiver outside the car?
I would agree with Crusin Through - I think your car may well have some form of heated windscreen or heat reflecting windscreen. What car do you have.
If when you do place the receiver on the outside of the car you do get good signal you can get a special anntenna that had an outside part and an internal part that you can fit permanently to the car so you can still move the thing about. Bit like a mobile phone antenna.
Alternatively as you have the XDA II you can get a bluetooth receiver an place it on the rear parcel shelf (I think the wider heating strips won't affect it - but can't confirm it.)
John, I wasnt suggesting you drive around with your window open, I was suggesting a way to ascertain if your windscreen is the problem regarding your blocked gps signal, by the way I have used a gps on the roof and the window will shut almost all the way however as the last post mentioned you can obtain a re-radiating antenna, this will solve your problem if indeed the windscreen is the culprit.
Re-rediating antenna - that's the word I couldn't remember :lol:
ok guys, thanks. i'll try with such an extern antenna.
thanks for your help
Before you spend your money on the re-rad antenna - try the thing on the roof - if this works then the antenna is your only real option if you want to continue with the thing in the front windscreen.
I'd hate you to buy the re-rad and then find it doesn't work.
Incidently what car do you have? (Does it have a heat reflecting or headted windscreen)
And if it works outside,
you still don't have to buy an external antenna, as normally the windshield have an area where is not metal coating...
try to check the manual of your car..
i own a toyota Camry 2002 model, it has indeed a windscreen etc...

Speed radar detection via Bluetooth?

Does anyone know if the following exists?
In Holland, it is prohibited to use a speed radar detection device in your car. Since such device is nothing more than a hardware detector using some kind of (embedded) software, I was wondering is a detector exists which can connect via bluetooth to a PocketPC.
This allows me to hide the detector somewhere in the car, and the PocketPC software will inform me of any nearby police agents busy detecting the traffic speed.
Note: This is not about the moral side of bypassing the law
It will still be a radar detector, so why not just buy a build-in model radardetector ?
You can hide that one also...

That's true, but how will I ever read out the LED's? Besides, when discovered, the dedicated radar detector will still be regarded a 'radar detector', as opposed to some small unit, hidden somewhere in the booth.
The MDA will just look like what is is, a pocket PC
well to me it dont sound like something that there would be a huge market for and when there is only a small market chances that somebody spend the R&D coins making such a device are smaller still

Well, it seems this could end up being my second DIY-project only a few people would ever value the use of it
Why not do this serial via rs232, this is a standard supported by every PCC.
Do a parallel to serial conversion with the LED from the radar detector and transmit it to the PPC via Cable. Have a small app displaying to value.
Just in theorie of course...

It's the antenna that is forbidden, not the thing that goes beep :roll: if they find the antenna you use for the XDA, the XDA will probably be confiscated also...
Stingers has a stealth mode, wich i would trust more tha any DIY radar detector/antenna...

Ah... This I didn't know, but it is key info though. Thanks! I will postpone my project then
I'm not sure if you're aware, but there are stealth systems where the antenna/radio is mounted up in the grill or bumper, and a very discreet sound/light unit is place in/on/under the dash. This would not be visible to the casual viewer.
However, keep in mind that detectors also emit their own radio signal, and there are devices that can detect that. In the US, two states have bans on detector usage, and the police there use the "detector detectors" to find people using them. I don't know if they are in use in your country.
In the never-ending one-up war of the citizens vs. the gestapo, now there are detector-detector-detectors and special detectors which don't give off the signals which the detector detectors look for.
That's what i said, buy a build-in model
A stinger has stealth (no leaking) , also Target an d Bell...

GPS satellite detection

Hi, I've got TomTom Navigator 6 installed on my Trinity and it all works fine, except it takes about 5 minutes before it picks up any satellites when I run it - does anybody know if there's a fix to enable to gps chip to pick up satellites a bit quicker than this? Even when I'm outside and away from tall buildings it's the same. Any help or suggestions would be great.
Thanks
Seagee
Did u try that software?
keep QuickGPS updated.

it will save a couple of minutes
aquiring a satellite regardless of whether you're using an internal gps antenna or an external bluetooth antenna usually takes a few minutes when you are booting it cold (ie.. turning it on initally) There really isnt any way around this that I know

Try your GPS antenna with an other software or with a GPS diagnostic.
I am 99% sure your GPS antenna does not work properly or at least try your tom tom with an other antenna.
Info : GPS antenna have to connect with 3 or more satellite to determine the position.

GPS Interference

I was wondering if anyone can explain why my GPS doesn't work while riding the train.
It works in cars, buses, trams and trolleys. However, in a 200km train ride, I wasn't able to receive GPS signal at all.
I tried to put the phone on the window of the train, there were no clouds above and the phone was at some points connected to a laptop by usb to recharge.
Does it have anything to do with the electrical wires used by the train to run?

Because the windows often are tainted with metallic particles (sun heat protection) and they do not let GPS signals through.

[Q] GPS not working on Nexus 7

Is there anything I need to do except turning GPS on in settings to get GPS working? My Nexus 7 can never find GPS signal, even when I am outside. Any APP to test it?
Apparently rebooting nexus 7 worked. Not sure why though, I didn't change anything settings either.
Sent from my Nexus 7 using xda app-developers app
GPS Status is a good app to see what the GPS is doing.
Sent from my Nexus 7
The nexus 7 have no data connection do download AGPS data, be sure to connect to a WiFi network and try using apps like GPS status to try and get a lock. And as long as you are near a windows, no need to go out, the gos chip in the nexus 7 is pretty sensitive.
Will the next nexus have a longer screen?
Hello, i found the "Bug" on my Nexus 7 - and it was Hardware.
There was simple no Connection between the GPS Antenna in the Backcover and the GPS Receiver on the Mainboard.
How to fix this? Pull off the Backcover, locate the GPS Antenna. Then locate the GPS Antenna Contacts on the MAINBOARD, and bend them upwards a bit, so that they will connect to the Metall Pads in the Backcover.
Have Fun!

Thank you! My GPS had been so reliable up until a few weeks ago that I figured the radio was damaged. Never thought to check those contact pins... I could see sattelites and get a fix, but the signal was so noisy that it wouldn't detect any movement, and it usually placed me a half mile away from my actual location.
Saw this post last night, popped the back off, gently bent all of those contacts up a degree or two, and BAM! All my radios are working very well again. :good:
