Ambient temperature, clock, GPS - MTCD Android Head Units Q&A

I replaced the stock radio in Hyundai with the MTCD-based one (Xtrons XL702AP) and I have basically two/three issues with the stock image/firmware:
- ambient temperature
- time resetting (connected with the last issue)
- GPS loosing the fix
Is there any analog input on the MTCD units that can be used for the resistive temperature sensor for ambient temperature? Originally, it was connected directly to stock radio (the ambient temperature is not available via CAN bus). If there is none, I am planing on connecting the PoKeys57U IO extension device to one of the USB ports and write a small Android app to show the temperature in the status bar. What do you guys think about this idea?
The second issue I have is that the unit resets time to 13:00 after each startup (short-term deep-sleep mode, which restores the radio function within seconds doesn't reset it) - it then needs the GPS to obtain the correct time, which may take very long time sometimes. Turning GPS synchronization for the time in the settings does not fix this, neither does disabling 'Automatic network time'. Again... I should be able to fix this with the IO extension device mentioned before since it has a battery-backed RTC clock on it, so I could re-synchronize the time on each startup (I will need root for that to accomplish).
The last issue - GPS looses fix randomly. I need to disable the GPS, wait a few minutes, then re-enable it to make it work again. When it works, it receives 10+ satellites, when it doesn't, no satellite signal is received/displayed (using GPS status)... It can work for hours, then suddenly just stops (no tunnel, no city with high buildings...). Is this a known issue? Are there any fixes?

Hi
I don't know a fix for the temperature sensor, but you may try a software update for the other problems. Ask your supplier for the latest MCU and ROM or you may try Malaysk ROM (see more here: http://bit.ly/2kfUVX2 )

[Q] Battery usage while GPS enabled, but not used

It looks like at least on some ROMs battery is drained faster when GPS is enabled (and no application is using it - at least GPS icon is not shown in notification bar) than when GPS is disabled.
Is this a bug or normal behavior?
If this is normal behavior, then why that happens and is there any way (other than disabling GPS when not using it) to turn this feature off?

Number 1 rule for saving battery: TURN OFF ANY FEATURE IF YOU DON'T PLAN ON USING IT.
Even if you are not using GPS software, the phone still feeds electricity to your GPS receiver if GPS is enabled. That's not a bug, its just the way things work.
yep it seems to waste battery whenever enabling wifi/bluetooth/gps and not using it

How to make the gps icon blinking when is searching for satellites?

When I open an app that requires positioning, I need to know if my position is determined with wifi/cellular tower or with gps satellites. On my previous phones I knew it because when the gps fix was not made yet, the icon blinked. Now on the sg7 the icon is always steady.
I have root and xposed... I have found an exposed module that could do this but it's only for kitkat.
Any suggestion?

You should have not understood my question (maybe because of my poor english). I don't want to disable cellular towers/wifi positioning. I only want to know, at a given moment, if my position is determined with cellular towers/wifi or with gps.
For example, if I open google maps:
1) The gps icon is blinking: this means that my position is determined with cellular towers/wifi
2) The gps icon stop blinking: this means that the phone got a gps fix, so my position is determined with gps
This is the normal behavior for 99% of the phones. For some reason in the galaxy S7 the gps icon stays steady so it's impossible for me to know when the phone get a gps fix.

HELP needed with Note 10. GPS accuracy issue, overheating whilst using Android Auto.

Hi
I've tried to find relevant info here but have failed...
Right were do I start?
I use Samsung Note 10 heavily for:
Android Auto
-Navigation (Google and Waze)
-Spotify
-Youtube Downloader (to play sound in the back ground)
-phone calls
GPS status app installed with A-GPS data updated.
Phone screen is always on with Courier Exchange app that uses GPS location etc
1. Main issue I get is GPS location accuracy whilst in big cities with Google maps (Waze is similar) , during navigation my position is shown with a delay and very often drive past the street I suppose to turn in or my position jumps to a street next to. After a stop for lets say 5-10 min if I start to drive again it takes about 60 sec until it picks up my location correctly again. Navigation works fine on motorways and in small towns.
I do use magnetic phone holder (the one that goes into a vent and with metal plate sicked onto a back of the phone) - could this be the issue? (never had that problem on Sony Xperia One) . Compass is calibrated and seems to be working correctly.
Phone additional Google accuracy settings (WiFi) needs to be on as this is requirement of CourierExchange app.
2. Second issue I get is phone overheating and slowing down dramatically.
As I've mentioned before I use Android Auto all the time ( for about 8-10hrs a day) , phone is charging constantly (fast charge off) and I do use Spotify / Youtube Mate to listen to music in the background. Had to switch off screen animation to speed the phone up.
I do have "Power mode" switched off for maximum performance. Phone gets very hot from time to time and tend to slow down, google maps scrolling on the vans unit slows down. Sometimes phone doesn't react on touch too.
Am I lacking the RAM here? Is the constant charging an issue (phone needs to be connected via USBcable to use Android Auto). My vent where the phone is located is closed so no hot air blows on the phone directly.
Is the phone simply too slow what I do or there's an Issue whit the phone? Phone is 3 weeks old and don't have many apps installed on it..
I did use Sony Xperia One (with magnetic phone holder in exactly same spot) before and due to its size and lack of dual sim option have decided to go for Note 10 (not 10+ which is too big). Sony worked so much faster and absolutely no issue with GPS between high buildings. Also I'm a little worried about lack of battery care by Samsung (or am I wrong?) as I constantly charge phone, Sony here was learning my habits and after some time didn't allow the phone to be fully charged whilst using Android Auto - had Xperia XZ1 Compact before and this one was also faster then Note 10 and after 2 years of heavy use battery is like new....
Can anyone help me resolve above issues? I still have the Sony One and thinking of getting rid of Samsung if the issues continue - this is costing me money.
For any help and advise what to do I will be very grateful.
I also experience the GPS issues you explain. Sitting still at a stop light and suddenly it's recalculating because I'm suddenly on a side street 500' away. I've never noticed any heat issue while using AA. I do not use any kind of mount. Also, my wifi calling often fails due to location unavailable error.

Sigma ID.FREE - is it possible to modificate firmware?

Hello!
First of all - sorry for my English, Im not a nativespeaker.
So, the situation is next. I have Sigma ID.FREE watch (https://www.sigmasport.com/en/produkte/wearables/id-series/id-series/id-free). Not a very advanced watch, but it have most of nessesary tools inside - GPS, barimeter, temperature sensor, ANT+, gyro, etc. Also this watch has killer-feature as for me - led indication in the bottom side.
But also this watch has weak software. For example - barometer cannot be seen without starting an activity, backlight cannot be activated for custom time period. And what is very sad - GPS navigation is very dissapointing. No ability to save location point, create list of points and start route to one of them.
Due to this all bugs I want to ask next: Is it possible to modificate firmware to add minimal GPS navigation functionality and also other several improvements?
I have never before touching with similar tasks but Im understand that this modofication is theoretically possible. So, how to check it? Thank you!

Question Navifly/Mekede M500S issues

Hi
I just got a M500S with 360 option and I'm trying to test everything is working outside the car before installing it but ran into some issues.
I'm testing by just powering it via gnd + acc + live, apart from this and the cameras, nothing else is connected yet because I'd like to get the 360 system working before moving to GPS tests, etc.
Connecting front/left/right/rear cameras doesn't show any input in the 360 app, its still all just showing black - same as without having them connected.
Pressing power button doesn't set head unit to sleep but mute/unmutes - not sure if this is because of a setting.
The date/time isn't stored if the head unit is fully powered off - it resets to last year everytime and doesn't sync automatically over network either. I think I saw something similar mentioned in another thread.
Anyone have any thoughts?

Change your country and region, and no, the date/time aren't stored in the unit !

Thanks, did change the country and region, guess it just doesn't sync over internet on boot like other androids...

Yes, it does sync, but that is something else than storing it on the unit.
If my unit starts from cold boot after 3+ days not being used, it will sync it's date/time as soon as it has internet. Either directly or via the hotspot from my phone.
And normally that is the hotspot from my phone as I don't want to wait 60 seconds or so for it to sync, but start driving immediately.
3second push on power does send it to sleep, but not to deep-sleep. Your power consumption will remain high.

It does but only after it has connected to the Internet which can take time after the boot sequence has finished.

I didn't mind it not storing - did expect it since it doesn't have internal battery power - although did think it would at least retain the last date/time before power off though.
It is odd that it doesn't sync for me - its not in car yet, I have it connected to home wifi - even after a few minutes after boot (~10 mins) it does not sync. Though not a major issue - just hope to get the camera working.
Yes, thanks, was just looking for the sleep option - mainly turning display off without using toggles in notification drawer, not deep sleep.

Hm... let me try again, since hasn't synced for me even after 10 mins+ after boot.

Just tried again, no sync even after half an hour after cold boot. Internet connects almost immediately after boot, but still no sync. Tried toggling the network-provided time option on and off again hoping it might trigger a sync, but no luck.

My mistake, sorry
Well its not working as intended then, try playing around with some settings in Date and time and rebooting to test, also have you got the GPS antenna connected just in case it uses the GPS sat times to confirm the time.

Thanks! This was it - I can see that as soon as GPS lock is established, within 2-3 seconds the time is synced.
Thanks also @mariodantas , @surfer63
With regard to the camera, I've still not had any luck.
Thought that maybe one of the other inputs powers the 360 camera module separately, so tried plugging into the car, but the 360 app still does not show anything with all 4 cameras attached. Anyone here have experience with installing the 360 version?
I've tried toggling two of the 360 camera options in Factory hoping it might show some signs of life, but nothing yet.
Thought I had the solution by connecting 12V to the reverse line, but not right solution.
Odd, I thought 360 was designed to be on all the time as it's for being able to see the blind spots even when moving forward. Will you need to feed reverse with 12v all the time or just when the car is in reverse.

Thought the same - recording when driving might be something I go for, so 12v via ACC is what I'm thinking, though ideally I'd like it to be powered just when reversing or when the 360 app is open.
The feed stops around 1-2 seconds after disconnecting the 12v.
Don't know if I'm missing an option, but if anyone has any ideas on how I might be able to get it to power up on when the 360 app is open, I'm all ears.
I don't have 360 so my headunit does not have the 360 hardware but the option are in the factory settings so will have a look.
2 settings in factory, what they mean could be anything as bad translation is normal.
Single 360
and
360 switch
Both with on/off options.
I did try toggling the two options before, but it didn't make a difference. Looking through one of the comments on 4pda, the second is to switch between stock 360 system and this. Though, tried again and can't see switching them making any difference.
Just tried again and saw that powering via reverse line means I can't back out of the 360 app and it stays on top, and also switches to reverse view (understandable), but there must be another way - I can see any looking at the pin config. Can't call it usable as is.

I’m having the same issue; I’ve noticed my 7862 when using maps on a long drive the background goes a bit pink/purple ish…
When I first connected the 360 cameras I only connected the left and right side - these were only connected by the CVBS connectors and worked perfectly out of the box - somewhere in between randomly they decided to stop working and all my 360 cameras don’t work.
I have played around with factory settings and can’t seem to get anything to work. Including the two options “360 switch” and “single 360”. I have figured out a front camera can work with the RCA cable that says CVBS in on the connector block closest to the fuse, but I am at wits end trying to figure out why all my 360 cameras show as a blank screen… possibly something wrong with the connectors behind the head unit or the specified chip these units are shipped with? I have contacted the manufacturer - in my case - navifly - but I was wondering if you’ve had any success @Moon2
