The 2nd Russion thread for IQ Navi?

In the 2nd Russian thread for the IQ Navi firmware there are several MCU files listed:

Using Google Translate the word 'Ревизия' is 'Revision' - so revision 1, 11 & 22 - I assume these are hardware revisions and they aren't interchangeable? I.e. there are only updates for Revision 11 hardware - 5.3.17 & 5.3.18?

Is this how you guys are interpreting this? I have the last one - 5.3.16-22-14-E50201-150729 on my head unit so there are no updates yet?

I installed the IQ Navi firmware and it is better. Still needs work though and I think a lot of the limitations are hardware related anyway - Bluetooth, CAN BUS decoder etc.

[Android Head-Units] Hisma:
what sort of improvements would we get with an MCU update? I am hesitant to do one since I don't want to perma-brick my unit.
[Android Head-Units] ADB100:
The way I understand it is the MCU controls the hardware on the unit that is separate to the actual Android system - Audio, Amplifier, Bluetooth, Buttons, DVD drive, possibly CAN BUS?

I suspect my main issues (apart from the cr4ppy Bluetooth) is the CAN BUS decoder.

Pls Need Help!!!!

Hi guys, I own a android car unit who look exactly like the first model (upper left corner from first page) who runs 4.2.2 android version, even in unit description (settings/about device) it says it is 4.4.4 version. The device runs well, but I started to have a few problems. One of them is about wifi , which have o loop when connecting (saying obtaining IP all time and no internet). I rlly want to resolve this issue and I don't know how. Maybe someone can help me with this!

also I can't root this device. I tried kingroot and other apk's but nothing. maybe because I don't have an internet connection?. also I tried to use my 3G dongle (ZTE MF101), who is connecting and show 2 signal lines, but also no internet. Can you give me some advice about this issue?

Another question is if I can root this device and if I can upgrade somehow android version or changing with a better one?

THKS!

When i installed mine, i had wifi issues too. I have 3 routers in the house and one of them which is closest to the car, did this. Can't obtain ip. I had to reconfigure the router. So i think you have router problems.
[Android Head-Units] fyid:
its been over a week now since i updated the software and i haven't had a boot-up hang since. i did some other things at the same time, so i'm not sure if its the upgrade or one of these:

- unrooted (and undid everything i changed while rooted), did not re-root after update

- removed microsd card (moved my mp3's to the internal storage instead, the sdcard seemed to slow down the boot anyway & i didn't really need it)

- changed the extra setting to not have it adjust volume based on speed (i'm not sure how this works, but it seemed to randomly change volume & seems better now)

- adjusted antenna jack to fit tighter (its >10 years old so i gave the wings a small plier adjustment so it would fit tighter - seems to have helped tuning a bit, although tuning still isn't as good as my original radio, its adequate)

overall its been great this last week, i've had 1 issue with sygic causing a hang to the whole thing, but as long as its infrequent i can just reboot by holding the power off button down a few times, so its easy enough to recover.

not planning on replacing the battery now, until i see some real signs of it dieing.

btw, the upgrade i was sent by my reseller is(or was) here - it did not update any of my version #'s (which i've posted in an earlier reply in this thread), so i'm not sure if the upgrade or something else above actually improved the hang issue:

[Android Head-Units] Hisma:
I don't think it was the update that fixed it as I've done several and the problem still persists. Being rooted isn't the problem either as I've had issues rooted & unrooted.

What I will do is remove my microsd card and see how that goes. I have yet to try that. One thing you see during every cold boot is the "storage mounted" message. So I will remove mine and see how that goes. I also have USB storage, but when I removed that I still had problems. So I assumed ditching microsd wouldn't work, but seeing how you tried it I will see if it works for me. I am determined to find a solution for this as it's driving me nuts.

[Android Head-Units] chechevara:
what is your MCU number and what version of android is this? i wana give a try to update my unit too with your firmware, maybe i can solve my Bluettoth issue with this
[Android Head-Units] fyid:
here's my previous post with that list: http://xdaforums.com/showpost.php?p=65240167&postcount=161

i just added it to my signature too.

fwiw, i don't use bluetooth much, but i have it enabled/paired with my phone and haven't noticed an issue offhand.
[Android Head-Units] Hisma:
fwiw, I've gone 2 days now w/o a failed boot. So I really do think that microsd card was the culprit. My particular unit had 2 microsd slots. One for GPS maps, the other labeled "dvd". I put a 32GB class 10 microsd card I had lying around in the "dvd" slot and loaded it w/ music. I think this was the problem.

The unit came w/ a really cheap looking 8GB card for maps. Likely a class 4-6, def not a class 10. I have heard issues w/ devices that can't handle class 10 sd cards, and this may be one of them.

Anyway, glad I did it and am upset it took me this long to figure this out as I've had my system several months now. It also seems to have addressed my bluetooth pairing issues, as it has also paired w/ my phone every single time since I removed the card. So it's only been 2 days, knock on wood, but for others here, I would recommend NOT using a high quality class 10 microsd card in these units. In fact, just use USB for storage if you can.
[Android Head-Units] fyid:
cool, hope it keeps working, mine is still going fine. i could put the sd card back in to see if it will hang, but i'd rather not upset the apple cart right now, maybe some day.

[edit: btw interestingly the sd card i had used was also a class 10 (sandisk 32GB)].

this is a kind of the reason i'm hesitant to try adding an obd monitor (or 3g modem for that matter). i'm worried its doing enough already & adding more will just break something else. anyone using an obd monitor have any issues with using bluetooth phone at the same time? is that even possible?

The correct thread?

Hello,

I found this thread while searching for community support for an Android head unit I recently purchased from AliExpress and wanted to check if this is the correct thread.

The unit I purchased is here.

Here are the details from the About screen:

Processor type: QuadCore-R16 1.6G

Android version: 4.4.2

MCU version: 4.3.16-7-10-650201-151120

System version: 4.5.6_20151226

DVD version: Unknown (*The unit does not have a DVD drive*)

So far the following I have tried from the first page of this thread.

USB debugging password: "john@tw-desktop" (Worked)

Factory reset / developer options password: 7890 (Worked)

Extra settings password: 123456 (Worked)

Rooting: KingRoot (did NOT work but I tried with many other apps open. I need to try again).

The above makes me feel that I am in the correct thread - am I right?
[Android Head-Units] fyid:
yes, it looks like the right thread for you to me also - welcome!

kingroot should work for you, i think it gave me a hard time as well but then eventually (or indeed had) worked.
[Android Head-Units] sansjunk:
Thank you! Did you try do anything specific to get it to work? And were you connected to internet when you tried?
[Android Head-Units] fyid:
nothing specific that i can remember. yes, i was connected via wifi since i was parked at home.
[Android Head-Units] BiliTheAxe:
You need to be connected to the internet to root with kingroot.
[Android Head-Units] Jacklad:
Has anyone been able to the 3g dongle working with a US carrier?
[Android Head-Units] sansjunk:
It was connected to the internet via my home router but the WiFi signal strength was a bit weak. I'll try again with a better connection and check.

I am seeing few quirks with this unit. If someone has a solution for these kindly enlighten!

The top notification bar shows couple of items (ex: download, install progress) but is not interactive. In the sense that nothing happens when I click on the notifications. And when I swipe down all I see are quick access buttons for settings etc but the notification list doesn't show up. So effectively there is no way to address the notifications. So the notification keep piling up and only way to remove them is to reboot the unit!

There is some sort of a launcher that shows up when the unit turns on or I press the home button and this has big animated icons for launching the navigation app, stock music app, stock radio, etc. However I can't find a way to remove/reconfigure these icons. It does allow me to add icons/widgets to the other screens and these can be removed by long press. But not the pre-built ones. The reason I want to remove them is because there are icons for unsupported features (ex: TV) which don't make sense for my unit. Also I want to replace the stock radio and music player with the radio apk provided in this thread and with Poweramp.

Even if I had turned off the unit by long pressing its power button it turns on by itself when I come back to the car and crank it.

The touch buttons have a red back light which is always turned on when the unit is on and always off when the unit is off. The former is fine but the latter is a pain at night since one needs to grope for the power button. The other equipment (Aircon, etc) buttons backlight lights up when the parking lights are put on.

There is a Chinese app called HiMarket that offers lot of updates to the apps and services that Google Play is not. It showing me update for Google Play services and Google Play app itself. However this app is very, very slow to download updates (about 30-40 K/s) while downloads from other apps is much faster
[Android Head-Units] thatguychad:
After you swipe down, tap the icon in the top, right corner.

All of these MTCP units have a default launcher that is not customizable. Switch to a different launcher, I'm using Nova Launcher Prime and I love it (iOS user for everything else.) The ability to customize icon sizes, colors, etc is great.

I'm not sure I understand this one. Do you not want the stereo to power up when you turn the car on?

The harness adapter you bought for your car should have an orange "illumination" wire. Wire the orange "illumination" wire to that one. If there isn't an orange wire on your harness adapter, or if you're not using a harness adapter (bad idea), figure out a way to either get it wired correctly, or you can hook up the orange "illumination" wire to +12v to have them always on.

I can't answer that since I don't use non-Play stores (huge security risk, IMO.)
[Android Head-Units] sansjunk:
Thanks, will try that. Instead I was trying to swipe left and right.

I will try Nova. However is it possible to set it up such that pressing the Home button takes to the new launcher w/o having to root (in the event that I am unable to root)? BTW is this a MTCB head unit? The MCU version does not have that string so isn't this a non-MTCB unit? I am happy if it really were MTCB since there is so much support here for them!

I want the unit to remember its last power status. So if I had turned it off before switching off ignition then I don't want it to turn on next time when I switch on the ignition - right now it always turns on regardless of what state it was in.

The HU has both ACC (red) and ILL (orange) wires but my car connector (ISO) does not have wires for this. I am guessing this could be because all the information is being sent over CanBus. Though the HU came with an external CanBus box I think this information is not being decoded. How are these wires (ILL) signaled? Is it +12/GND for turn on/off? If so I can try pulling a wire from the parking light and connect it to the ILL wire. Also what purpose does the ACC wire serve? Does it help in remembering the status since in my unit that wire is not connected to anything at all.

I agree. I will get rid of this app now that I verified Google Play works fine.
[Android Head-Units] ADB100:
The IQ Navi ROM has been updated to version 0.1.14 :) Russian IQ Navi thread

I was getting excited as the release notes mention something about CAN BUS :

I have installed the ROM, however I can't see anything that mentions CAN BUS in the settings?

Software seems quite stable though - still with limitations due to the hardware

Andy
[Android Head-Units] thatguychad:
No root necessary to run a new launcher. Download your launcher of choice and set it in preferences as "home".

I may have misspoken here, I'm not sure, but my MTCB HU also had a stock launcher that wasn't very customizable.

I'm not sure that this unit will behave in that manner, but I can try it on my test bench since it's not installed in the car yet.

That's possible, I don't have any experience with aftermarket HUs in CAN cars.

Yes, ILL is +12v for signal. The ACC wire is for switched power, your yellow +12v wire is constant. I'm surprised that you don't have the ACC wire connected, I assumed it would need both connected to power on/off, so I didn't even try that configuration on the test bench.
[Android Head-Units] sansjunk:
It's possible that the HU wire harness had the +12V (yellow) and ACC (red) tied together - I don't remember now. I will shortly be removing the HU from the car to install a powered FM signal booster since the HU came with just a passive connector. I will check then on the ACC connection. I too was surprised when my car ISO connectors didn't have any pins for ACC and ILL.
[Android Head-Units] sansjunk:
I came across this other thread and a wiki. All the passwords are the same as our unit but the rooting process is different (KingRoot vs. Baidu Root). So are both threads talking about similar devices? Just trying to get more community support :D
[Android Head-Units] BiliTheAxe:
There are many similar units to these out there. They are similar, but have enough differences that you have to be very careful when installing updates.

One wrong update can brick the system.
[Android Head-Units] sansjunk:
I was finally able to root my head unit using KingRoot. Though I was connected to the internet and had just rebooted the device it still failed. I then force stopped all apps/services other than the Google's services and that's when it worked :good:

I remember reading somewhere in this thread that the unit doesn't support delayed shutdown - however there is a setting in the Extra Settings for this and when I set this to a non-zero value I am finding that after I remove the ignition key the head unit turns off but the USB ports still have power and when I put the key back in and turn it to ACC position the unit immediately comes on. :) However there is one smaill problem which totally negates this cool feature - from the ACC position when I crank the car to turn it on, the head unit reboots :( I need to find some way to prevent this. I think its the CanBus asking the head unit to turn off. Need to find the lead for this and disconnect it and check what happens.
[Android Head-Units] fyid:
mine does this also, but only occasionally. i was thinking the battery wasn't quite strong enough to keep up with the cranking and keep voltage up enough for the radio, but not sure. the delayed shutdown works fine otherwise.
[Android Head-Units] Prison91:
Some cars need to flip the ACC and the B+ cable, because the B+ is an always +, the ACC is when you crank its not have voltage.
[Android Head-Units] sansjunk:
My car is new so I think it isn't the battery. I suspect the CanBus is doing it since the car manual clearly states that all in cabin equipment is momentarily powered down when cranking the engine.
[Android Head-Units] Prison91:
This is not a can bus function. Every car do this. This function made by the "X relay" which turn off everything for the cranking time.
[Android Head-Units] thatguychad:
Does it take anyone else's unit a long time to mount the SD card? On my MTCB unit, storage is mounted with 5-10 seconds of booting. On this unit, it takes a full minute or more with a 50% full 64GB SD Card (exFat-formatted). System version 4.5.3_20151027.
[Android Head-Units] Hisma:
my sd card is mounted the moment my unit cold boots. something is definitely wrong.
[Android Head-Units] sansjunk:
Are you saying the Battery+ (usually yellow colored wire) is routed through this relay as well? Seems unlikely since this is supposed to be an always-on supply. The reason I ask is that in my car ISO connector there is no ACC (red) wire so the powering down during cranking can't be controlled by this via the relay. That's what makes me think it could be the CanBus?

My unit doesn't have an SD card slot. However the USB drive is mounted almost immediately (it's 32GB and about half full with mp3s).
[Android Head-Units] Prison91:
I think you should check the + cable on cranking first. What type of car you have?
[Android Head-Units] sansjunk:
It's a 2016 Volkswagen Polo.
[Android Head-Units] Prison91:
Send me a PM with the vehicle VIN number. I am in a VW service so if i don't forget I will try to see the wiring diagram for it.
[Android Head-Units] sansjunk:
After rooting the unit I sometimes find the unit stuck during boot up. It just continues to show the Android boot logo forever. This doesn't happen always and only way to get out of this is to power down the unit which means I need to stop the car, remove the ignition key and crank up the engine again :mad: There is a reset pin hole on the face plate but I am not sure if this will factory reset the device so haven't tried it!

To investigate the boot issue I wanted to check the Android log during boot (using ADB) so is there any way to hook this up to the PC via the USB port? The unit only has two female Type-A USB ports - there is no micro USB slot.
[Android Head-Units] Hisma:
pressing the reset button does not factory reset, it simply does a hard reboot, which is what you want. The only thing I notice with my unit is that it re-adjust the volume to a pre-set level, and switches output to FM radio during boot. Other than that everything else is retained as normal.
[Android Head-Units] fyid:
do you have a microSD card inserted? a few of us have seen hangs with a microSD card in, but not with it out.

do you have a power button? you might be able to reboot without turning the car off by holding the power button down for a few seconds, let go, then hold it down again a few seconds to turn back on.
[Android Head-Units] sansjunk:
OK that's good. I'll have to keep a tooth pick handy to reboot the unit till I figure out the boot issue. If I am not wrong it happens if I crank the engine when the unit is still booting the first time (and usually showing the car manufacturer logo, in my case VW) and this boot is interrupted and it has to boot again. In my unit the volume does get reset to a preset level (I believe there is a setting for this in the Extra settings?) but the output doesn't get switched to FM radio. What exactly do you mean by that? The radio comes on every time after boot?

My unit doesn't have an SD card slot, however I do have a USB stick plugged in with songs on it. As I said the boot hang issue doesn't happens always. Unfortunately all controls on the face are touch so long pressing the power touch button does nothing! I guess the unit hasn't reached a point where it can handle touch input.

So I take it that no one here has managed to hook up their units to the PC via ADB and the available Type-A USB ports?
[Android Head-Units] furry:
I wish I knew which internal wires to tap into to keep the android OS board powered on continuously and only power down the radio/amp parts of the head unit with the key-off. That way the parts of the radio that pulls amperage would power down but the OS would always be loaded, that would eliminate boot issues and Bluetooth issues and most all other issues we are having!!
[Android Head-Units] thatguychad:
There isn't one, that's not how they were intended to operate. Most people would like to be able to start their cars after parking it for 12-24 hours.

Can anyone tell me which 3g (or better yet 4g) usb dongles will work with these units. ... seller wants an extra $50 for it, and won't tell me make/model other than "it'll work with your unit" seems way overpriced for a 3g dongle to me..... so want to see if i cam find something compatible on ebay.
[Android Head-Units] thatguychad:
I know this doesn't answer your question, but...

I skipped a USB dongle and went with an LTE hotspot from Walmart (internet-on-the-go www.internet-go.com). Most of the compatible dongles are only 3G and I can use the hotspot with anything. I'd hotspot my phone, but AT&T won't let me because I'm on an unlimited plan (on iPhone).

I went with this brand because they seem to be truly pre-paid LTE internet. Your data won't expire if you download at least 1MB every 60 days.

I did have some problems getting it activated, but once past that, it's been great. The car I have this head unit in isn't daily-driven, so I haven't used the 300MB yet. I went with the cheapest initial investment as a trial since I wasn't sure how my data usage would be (and still don't), but I think this will work for me.
[Android Head-Units] BiliTheAxe:
I'm going to be using one of these for wifi in the car, along with an Alfa long range wifi adapter.

You log into the device on this page and it allows you to access any open wifi signals within range..

It runs off of twelve volts so it can easily be wired into the car, and the long range wifi adapter plugs into it.

It will also work with a wide range of 3G modems, so that gives other options.
