General IDOING UIS7862 with WRX[Updated with initial review]

[gottahavit]

Thanks but why do you think the gray is the top left of the sticker pic? The side of the harness I am showing is the non-clip flat side of the connector which is the left side of the sticker pic. Wouldn't that make the far white wire the upper left of the sticker pic?

EDIT: I think I'm just dumb..let me look at it all again lol.

Were you able to get it working, did it help the noise? Hoping you didn't cook your stereo!

Hey sorry for the delay. So I haven't wired up the noise filter yet because someone on a Subaru forum told me to try removing the small blade connector bracket from the back of the OEM HU and screw it on the back of the iDoing and connect the factory ground wire connector to it. I hadn't done this or thought to try it so I did and unfortunately it didn't make any difference. He thought because I didn't have the ground connected that some noise was comig through from an unclosed circuit of sorts, but no change sadly.

I will still try the noise filter, hopefully today or this weekend. Shouldn't take long. Not too hopeful but you never know. I will report back.

Question for you - have you figured out any way to re-enable the notifications in the iDoing's custom ROM without root? Obviously they customized it to totally disable all notifications from happening at all or showing up in the pulldown shade. It would be nice to be able to have certain apps show up like they intend to like PowerAmp (for current song playing) and messaging apps. Any idea if this is possible? I have yet to do the ADB commands to get System UI Timer working but I don't think that will help at all.

I'm actually working on an app(who's main purpose is different) that will provide system overlay notifications to be displayed. There are other apps that allow this as well, tho I've had issues keeping them running on the IDoing. The main purpose will be to mirror notification from your phone without needing a cloud service like the others that do this, but it will also allow you to show the notification you get on the HU.

That's cool. I actually just downloaded Mighty Text on my iDoing to at least get texts on there and thankfully it has a popup notification window option..otherwise I wouldn't get any notifications from it and would have to go to the app manually to see anything. Would be great to have ongoing notifications of things like music and certain messaging apps like I said in my last post but so far no solutions for that on this custom ROM...
Let us know more about your app when you have it!

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?

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.

Thanks. What about the ground (see my last post)?

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! ;-)

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?

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.

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

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..

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.

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!

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.

Not worth it to me to lose the iDoing but interested if it works!

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

when yo did factory reset did you lose any pre-installed apps? Carlink?

Pre-installed apps were kept.

Yeah I've made it work wireless with the wireless proxy on the phone, but not with native AA wireless.
