So I'm trying to figure out where to splice in the noise filter. If the yellow wire is the 12v batt+, I see that it branches off from the main HU connector to two separate yellow wires (one to the Canbus and one to the white connector that connects to the factory harness. Where should I splice in the filter? Not sure whether to cut the yellow after the two yellows join, in that small length before the final black HU connector (not much wire or space to play with there) or somewhere before that at either of the two separate branched yellows. What do you think?

Also where should I wire the filter's black ground wire to? Should I remove the connector from the stock HU chassis ground wire and splice it to that or is it supposed to be spliced into the HU harness's ground wire that goes.to the black connector? Or somewhere else entirely?
[FYT Android Head Units] gottahavit:
personally I'd wire it as close to the plug on the HU as possible if it's to have any benefit you don't want any chance of contamination after the filter before getting into the electronics of the HU.
[FYT Android Head Units] just4747:
Thanks. What about the ground (see my last post)?
[FYT Android Head Units] gottahavit:
I would wire both right off the plug to the HU, it probably doesn't really matter, but that's what I would do. I am skeptical that any of this will matter as I can hear differences in the static based on what's running for apps in the HU(High CPU more weird sounds). What is odd is that it doesn't increase with the volume, which would imply something being introduced post-DAC,, post-AMP which would make me think maybe Ferrite on the 4chan would be best bet, but again it's probably too late. I suspect it's internal interference inside the box post-DAC./AMP

I hope you find the solution, but I suspect only way to solve is to run spdif to a DAC or DSP/AMP, which if you don't have the HK system, would be a pretty good Add to the car. With my HK i'm pretty sure I'd spend a bunch of money to get spdif->RCA->Spkr Level to get to the HK AMP and probable end up with some really messed up sound quality. In my corvette it just wouldnt be worth it as I always drive with the top down and at highway speeds I mostly just care about loud! ;-)
[FYT Android Head Units] just4747:
Hey was finally getting to try this but the ground wire doesn't make sense to me. How can I wire that into the same harness when there isn't two wires (one for input and one for output) for ground from the filter? Are we sure that the filter ground wire isn't supposed to just go to the chassis/car ground or the metal frame of the back of the HU? Can't be the HU harness itself right?
[FYT Android Head Units] gottahavit:
Ground is ground you don't need in and out. you just need to ground the unit and the HU. You could def ground to the chasis. You could do the same with the HU. In my corvette I have a couple grnd wired to the harness grnd. So HU Harness and FIlter to same Car Harness Grnd.

Features​

Electronic Noise Suppressor: This Electronic Noise Suppression Filter (AX-ANR1000) by Axxess Integrate is designed to actively cleanse noises generated by sources such as generators, alternators and inducted radio frequencies from the positive voltage line in mobile audio systems. Handles up to 35 amps.

Green wire is the power input

Red wire is the output to the source

Black wire is ground
[FYT Android Head Units] just4747:
Yeah figured so, ok. I wired up the noise filter I think correctly and as you thought, no change. I'll try switching the input and output wires because the booklet labels them one way but if you open up the filter box they are labelled the opposite - that the green is really the red and vice versa). But otherwise, might not do anything for this issue.

EDIT: nope switching them didn't work...HU doesn't even get power since the input and output were right the first time (duh). So I guess it's a no go then..
[FYT Android Head Units] gottahavit:
That's a bummer, but not unexpected. I believe the noise is introduced inside the HU based on fluctuations in the noise with cpu usage. Since the IDoing has no optical and I have the HK, that pretty much leaves me leaving it as is. I may however try introducing a cheap amp and an optical DAC into the corvette setup just to see what it does. If you don't have the HK, I'd return the IDoing and get a Joying with Optical.

All that said the IDoing still sounds fantastic with the HK system and I am very happy with it, it's just annoying when you are sitting in the car with it off and hear the static.
[FYT Android Head Units] just4747:
Yep I agree. And I have HK in mine so won't be trying anything else I suppose. Let me know how anything further that you try goes though!
[FYT Android Head Units] gottahavit:
Well you're only other option if the static bothers you is that Maestro RR finally added support for the HK, so for the cost of a "branded" HU and about 200-250 in harnesses and dash kits, you can have HK support and probably superior sound. Of course your HU will be limited to AA/CP and will not have that OEM look and the whole system will probably cost 600-800 for decent 7" HU and kits.
[FYT Android Head Units] just4747:
Not worth it to me to lose the iDoing but interested if it works!
[FYT Android Head Units] gottahavit:
Yeah I'm sticking with the IDoing even though I have a 600 dollar Kenwood HU that I could use if I bought the other kits. I just love the look of this combined with full android and the sound is still VERY good.

Remind me how I get rid of the double reverse lines? I did a factory reset and forgot how I initially got rid of one set of lines.

NVM. It's in factory > original car agreement, if anyone else needs to know
[FYT Android Head Units] gottahavit:
when yo did factory reset did you lose any pre-installed apps? Carlink?

Pre-installed apps were kept.

Hello everyone,

I am new here and have this UIS7862 head unit on my 2016 WRX (no HK). I can't seem to find any other forum on the internet besides this one about this particular unit so my apologies if something about the way I'm posting this is violating some etiquette in some way, but it seems like a number of different things are being addressed in this same thread so here's one more...

I have been having an issue as of late that I cannot figure out what is causing it and I'm going mad trying to figure it out. When the unit first wakes from sleep, there is a glitch on the bottom of the display (see photo). Sometimes it goes away within a few seconds, sometimes a few minutes, and sometimes it just remains there until I do a full reboot. It never used to do this. I have been in touch with iDoing (I just installed this in May) and they are wanting to send me a new display to swap out. I'm reluctant to do this as I'm questioning if I can even remove this thing from the dash without breaking something. It was scary enough having to push it in so hard to install it. Also, I'm not convinced the issue isn't software related, however, and they don't even seem willing to troubleshoot that route. I think they are trying to be helpful, but the language barrier is a major inhibition. Anyhow, the affected area of the display still is showing SOMETHING (not dead or stuck pixels), it's just as though the screen weren't calibrated for the display size or something, but it's definitely working and I can see it update as the rest of the screen changes. I have been working around this for the time being by disabling the sleep feature in settings so that each time I turn the car on it does a full boot. When doing a full boot, everything loads normally without the display issue, every time. I'd like to be able to us the sleep setting though, as I always used to, since it's much faster. I have tried doing a factory reset to no avail. I actually question if the factory reset even works correctly as there were a number of system settings that somehow remained how I had set them after the reset. It also seems to do this regardless of what launcher I'm running (either stock or Car Launcher Pro). So with that background, here are a few questions I have:

1) Is there any other way to do a factory reset besides from the system settings like I've tried? Maybe from recovery? If anyone even knows how to get into recovery on this thing?

2) Can you think of any setting or app that would cause an issue like this?

3) Is there anywhere to check for software updates for this thing? I have asked iDoing and they won't answer that question, which is very frustrating. If these things are known to be buggy I don't understand why there is no OTA update ability or at least a clearly designated site to find the latest...

Any other comments/thoughts/suggestions/snarks are welcome.

Thanks in advance guys.
[FYT Android Head Units] gottahavit:
sorry been out of the forum for a couple weeks. That's what happens when things just work ;-)

Sorry about your unit. I would definitely suspect this is either a display or connector cable issue. Like you already did, I'd do a factory reset first, but if you did that and IDoing is willing to send you a new display then I'd definitely have them do that. I nderstand your concern with removing the unit(I haven't had to yet), but honestly the only thing you're going to damage removing it is the display. I'd start popping the clips around the screen first, then the botton, then the top. Once you have it out I suspect the display will be easy replace, tho I am not sure how it is "glued"? into the bezel.

Good luck, let us kno.

I ran my mic under the dash and mounted it on top of the steering column ion the instrument cluster. Can't really see it unless you're looking for it. Rarely make calls in the car, but the voice recognition seems ok as long as the music is at reasonable levels.

Does anyone know of a GPS app I can install that doesn't require my mobile data to be connected? The head unit came with an app that seemed to work but I had to reset it and lost the app. Currently the only way I can use GPS via the head unit is connecting my cell phone to it or use downloaded/offline maps.

I'm having a really weird issue where the steering wheel buttons only work after the car has been running for a few minutes. If I reprogram them as soon as I start the car, they work fine but then stop working after a few minutes. I'm not even sure if this is an issue with the unit or just the car electrics. Even with the stock unit, the steering wheel buttons would randomly stop working once in a while and I'd have to restart the unit for the buttons to work again. Anyone experience this?
[FYT Android Head Units] mastrv:
That happens because of the temperature, I believe. It has happened to others and it happens to me. I have resistive buttons and from what I read, and it kind of makes sense, the resistance changes in colder / hotter temperatures. It usually affects one or two of my buttons more than the others. After the interior has warmed up a bit, it goes back to normal and all works better. Only happens in really cold weather, though. I remember reading something that suggested it's because the resistive values are too close together. The resistance values is how the head units know which button has been pressed. I remember reading about someone who put additional resistors somewhere in the path and that helped or solved the issue. I can't find it again and I gave up looking for it.
[FYT Android Head Units] abnormalreply:
Temperature effects on resistance makes sense.

I have bigger problems now though. The unit just died out of nowhere--lost power completely and doesn't turn back on. The Audio Amp fuse looks fine and so does the fuse at the back of the unit. Idoing says I can ship it back to them for a replacement, which I may end up doing.

Question I installed the Idoing Head Unit in my 2017 WRX that had Harman Kardon and unit works but the speaker output sound is louder on the front Passenger side. If i change the field and **** to each corner of the car its softer on driver front and rear and passenger rear but way louder on the front passenger.. Any idea's why ? Speakers worked fine with stock head unit

No idea, I'd contact Idoing. Any chance you didn't leave starlink connected?

I just bought joying Unit for my forester xt with harman kardon. It works perfectly. You need to make sure the wire to power the amp on is in the right location. On my car is the blue wire on the car harness. The harness that came from Joying was wired on the wrong location. This is my second android head unit, and I am very impressed with it. I upgraded from an px5 to this one. I opted for 8 gb of ram and 128 of internal storage.

Anyone have an issue where the default home/launcher app keeps resetting? It never used to do this, I'm hoping its not a sign of RAM going bad or something. Basically I have a default launcher set and sometimes (but not always) when I press the home button it will go to a particular stock UI (I think its UI11). This happens regardless of if I'm using a 3rd party launcher (FCC, Car Launcher, etc.) or one of the stock UI's included with the unit. I have tried clearing caches, and even got the latest update from iDoing (dated February 2022) but neither seemed to fix this issue. Only other thing I can think to try is a factory reset, but I'm not really wanting to do that unless I absolutely have to since I'll have to set everything back up...

Sorry to revive the necro thread, but I've been searching for lots of information and can't find out why my mic isn't working. Same (or very similar unit) to yours, in a 2017 WRX STI with HK, canbus installed, everything is working except the mic. I can't get it to pick up anything anywhere.

I made a separate post about it, and was advised to remove the mic and test in a laptop; haven't done it yet due to being busy + very cold weather outside + really don't want to undo my flush clips (they are hard).

I DID go to factory settings and try to enable the mic; no results.

So does yours just 'work'? and are you using the external mic or the one on the HU? Thanks in advance
[FYT Android Head Units] gottahavit:
yeah my mic just worked I'd suggest pulling it and testing it on another system
[FYT Android Head Units] kfkWRX17:
Yeah that's my plan, I just don't have another system to test it with. Fortunately, it's a 3.5 mm jack and then a harness. I know someone locally who has spare mics, so I'm going to pull the mic off, try to plug it into a computer, see if that works, then get my guy to see if he can send me a known working mic and try that. That. If neither of those work, then it's the harness or the unit itself, I just really hope it's not a software issue with the unit.

Idoing did reply, but they gave me the basic troubleshooting steps and those weren't sufficient, then they asked for the wiring diagram for my old head unit to see if they could make the harness to retain the old functionality of the stock mic, since my head unit is a little bit different than most of the ones for my car

It doesn't help that the inputs are on the back of the unit, not looking forward to pulling the dash again
[FYT Android Head Units] jdm419:
iDoing is now providing the parts for free so you can use the OEM Mic, You will also need to update your system firmware to get the settings.

Also you can use an adapter to use your stock GPS and USB ports.

I know this is an old thread, but I have the iDoing installed in my 2016 WRX non HK. Everything works great however every once in a while the head unit starts stuttering.

[FYT Android Head Units] j0hn83:
If you mean the settings for internal mic/external mic then these settings do nothing unless it's a newer device with 7862S hardware with the dedicated mic port on the rear.

For older devices both mic are always enabled, no matter if those settings show or not.

Basically if your device is old enough to have firmware without the mic switch in the options then the switch probably does nothing.
