Manufacturer is inadequate. He completely refuses support me, but respond when i wrote from another email as a "new buyer".

Here is dialogue:

* Me

... something about "i'm new buyer but hear about problems" ...

* "Mr.Charles" <sales@zhinavi.com>:

hello

all problems has solved

thank you!

best regards!

ZhiNavi Group

* Me:

Glad to hear. Can you take video with any android stereo test app?

* "Mr.Charles" <sales@zhinavi.com>:

http://www.youtube.com/watch?v=skN1h9Z7uAs&feature=youtu.be

* Me:

I do not see any stereo test in your video.

Could you install this app: https://play.google.com/store/apps/details?id=com.jasonfarrell.stereotest and get video with it in work?

* "Mr.Charles" <sales@zhinavi.com>:

yes..all working well now..

please check photos as attached..

* Me:

This screenshots do not prove that stereo problem is fixed. There is a lot of reviews that demonstrate mono problem.

Hi

Already solved all problem as i told you before..

thanks!

I think he even do not understand a problem.

Currently seller exchanging current devices to new. He said that devices will be reflashed and some hardware will be changed. This is so strange support policy that i think manufacturer will never release any firmware update - not for current devices nor for "new".
[Android Head-Units] Drakey83:
Are you saying that you don't think they are going to release a 4.2.2 firmware update?
[Android Head-Units] nE0sIghT:
No. I think that you will stuck with one firmware version and never receive update if some problems happens (only HU exchange). And i think that current 4.2.2 firmware do not solve all problems.
[Android Head-Units] Drakey83:
If we get a big enough community with these units than I'm sure that people, who are a lot smarter than me, will be ale to rip the newest updates from the newest devices and release them to the community if the sellers and manufacturers aren't wiling to update them without sending them in. I find it hard to believe that they would really want to go through all that trouble and money just for a firmware update. Maybe there is something wrong, hardware wise, with the original 4.0 android units and that's why you had the mono sound problem and why they are making you send it in to get it fixed at the factory.
[Android Head-Units] nE0sIghT:
This is seller's initiative, not manufacturer's. Manufacturer just begin to ignore me when i ask him for support
[Android Head-Units] Drakey83:
I find both the sellers and the manufacturers that are attached to this HU to be very incompetent. I wish I had just went ahead and bought the AN-21 U so I didnt have to deal with all of this bull ****.
[Android Head-Units] jpapadami:
I was in your shoes at one point and was really thinking about getting this unit. But thanks to donaldta his #2067 post at the AN-21 U forum I decided not to go for this unit. Instead I opted for this 7" Deckless. I haven't received it yet, but have heard nothing but good reviews. I was able to request it with DVB-T, red LEDs, 2 USB ports in the rear, and external mic for $460 + free shipping + 8GB micro SD card. After purchase, I waited 6-7 days and then they sent it out. I am really happy with their customer service and in case I need firmware related support, I can also rely on the AN-21 U forum because my unit uses the same firmware. If it's not to late try to cancel the order and get your money back.

[Android Head-Units] saidak:
First Thanks for sharing!

Second, the video shows some positive news, Android 4.2.2 and I like the webcam recording option (although that might have been there from the beginning and I did not see it). I think it is only a matter of time before things are properly fixed, although for initial adapters I am not sure if this will help. Unless that is someone is able to rip the new firmware and share.
[Android Head-Units] Drakey83:
Nice video! From what you can tell does it show any of the previous problems as being fixed?
[Android Head-Units] nE0sIghT:
FM radio app was opened about 40 secs - this can be too fast for "buttons hang" problem appearing.

No stereo test - manufacturer refused to demonstrate it; i asked seller - no answer for now.

Play market definitely works, but storage problem can be not fixed.

And i do not know how to demonstrate "low frequency filter" problem in video -)
[Android Head-Units] Drakey83:
I know those weren't shown but I know there are also smaller problems that I've roughly translated from the Russian site and I was wondering if it looked to you like anything has been fixed. I'm not sure I understand them all because of the translation and there seem to be too many for me to remember so that why I asked.
[Android Head-Units] Nereth1:
What is the storage problem you refer to that can't be fixed? Are you referring to the only 300 meg of app storage?

As mentioned a few pages ago, you can use an app to store other apps on the SD card, no?
[Android Head-Units] Drakey83:
As English isn't nE0sIghT first language I think this is just a case of broken English. Don't get me wrong nE0sIghT, I can't speak even a word of Russian so I think your grasp of the English language is pretty incredible. Anyways, I think what he was trying to say is that the storage problem could still possibly NOT be fixed as it didn't show anything about it in the video.
[Android Head-Units] Nereth1:
A good point, and yes I don't speak anything but English so I don't get to complain about other peoples English :p

It does seem like the kind of problem that may not be fixed however - it's less of a bug, more of a poor design decision. Ergo not a candidate for fixing in the first update.

But after reading through that whole 3 pages or so regarding that problem, did anyone check if saving apps to the other SD card ended up being a valid solution in practice?
[Android Head-Units] Drakey83:
I don't think we know for sure if it has been fully tested. I will test fully once I get mine, if I ever do get mine, and let everyone on here know.
[Android Head-Units] nE0sIghT:
Yes, thanks for correction

Link2SD in auto mode, manual linking download folder to sd card and manual linking firefox profile to sd card solved this problem for me.
[Android Head-Units] Drakey83:
Holy crap! I actually got my tracking number! I'll let you guys know what o find out once it gets here!
[Android Head-Units] Nereth1:
Sounds good, as I am literally waiting on someone to confirm how many problems remain with this update, before I purchase one of my own!

New video from seller: http://youtu.be/VbJMMET4rq8
[Android Head-Units] saidak:
Thanks for sharing. It looks like the app space issue is resolved or am I wrong?
[Android Head-Units] Drakey83:
That's what I got out of the video. Thanks for the repost!
[Android Head-Units] Nereth1:
Ok so what problems remain to be tested?

1) Android generated audio comes out of driver side front speaker only. Easy check.

2) Potentially radio still freezes the unit - needs to be tested by just leaving the radio on for say 5-10 minutes and observing

3) Low frequency filter on radio. Not sure how to check?

Anything else?
[Android Head-Units] Drakey83:
Could somebody please explain the low frequency filter problem to me so I know what to look for and how to test it once I get my unit?
[Android Head-Units] nE0sIghT:
I can not say for sure. My HU shows 2 GiB of free app space, but really there is only 300 MiB. 2 GiB can be used for audio, video, photos etc

Android generated audio comes out from all speakers. But there is only right audio channel in all speakers. Can be checked with any stereo test app or mp3.

You will just hear this -) Effect will be same if you cut off all frequences lower than ~400-600 HZ in your favorite audio player
[Android Head-Units] Drakey83:
My seller game me the tracking number on the 1st of April but the only information I was able to see on my end was "Shipment information received" and "Awaiting Receipt". These statuses seemed a little fishy to me and it seemed even more fishy when they still haven't updated, now 3 days later. I did research and found out that it probably mean that he only registered my package and still hadn't dropped it off to the shipping company. I confronted my worthless SOB of a seller but of course he promised me that he sent it out already, and in fact the shipping company has had my package since last Friday, then he made up some excuse about how my tracking information wouldn't show up until it arrived in America. I knew he was lying so I called DHL to see what they had on record, sure enough they confirmed that he printed out a mailing label for my package but he still had not dropped my package off to DHL, that stupid prick! Once I told him I called DHL he got offline and stopped responding to me.

Anyways my question is, have you guys read about anyone actually getting one of these units yet since they have upgraded to the 4.2.2? What I am trying to figure out is if my seller is even planning on sending me a unit at all or if he is just trying to rip me off. I figure if other people are getting these in the mail then they are obviously out of development and my seller should have access to them, i think that if this is the case than he is clearly hoping that ill just let the 30 day timer go by and he will get $500 with out sending me ****. The more likely scenario, I hope, is that he is VERY dishonest and keeps lying to me to shut me up so that I will leave him alone because he doesn't have any access to these units yet. Either way I am tearing my hair out in frustration. I don't know if I should just pull the cord now and contest the transaction or see what happens and wait even longer. I mean I paid for this on January 28th, whats another week or two right?
[Android Head-Units] Nereth1:
I don't know how things-that-are-not-paypal work, but do *not* let your 30 day 'time to file complaint' go by without receiving the goods. Be upfront about it, that if you do not see shipping data by [reasonable shipping time+safety factor] then you will have to get your money back either by him doing it voluntarily, or by filing a complaint, just in order to protect yourself due to that system. You may wish to reorder the product 30 minutes after cancelling it (I have done this, and told suppliers I would do this just so they understand I am sincere about wanting the product) but do not let your protection expire before you see the goods.

Best case scenario he gets off his ass and actually sends it because he really wants your money and he is scared he will lose it now, or he was never gonna send it and you extending your protection means you get your money back. Worst case you have to jump through a few extra hoops and you get your goods in the end anyway.
[Android Head-Units] junglizste:
Did you order it with a good credit card?

Every credit card will protect you against scammers. Most will protect you if you buy a malfunctioning POS. Visa Signature and AMEX will even increase your warranty by a year(with some caveats)

You'll probably have better luck with a real credit card, not a check card. But you should still have decent protections with a check card.
[Android Head-Units] Drakey83:
I ordered trough Aliexpress.com which puts your money in an escrow account until you verify that you have your received your item. You have 30 days after "you receive your tracking number" to make a claim that says you think something fishy is going on or to say you never received your order. If you don't do anything, after 30 days the seller automatically gets your money.

I really would like to get it from this guy because I cant find it for as cheap as hes willing to sell it anywhere else plus I'm supposed to get 3 extra things for having to wait so long and he gave me free shipping. But then again, if hes scamming me Ill never get anything. I think I am going to just wait it out and file a claim if I still haven't received it after I've waited for like 20 out of the 30 day. My joke of a seller still hasn't gotten online after I told him I called DHL so I still don't know his excuse but either way I don't believe a word that comes out of his mouth.

The whole reason I decided to buy from Aliexpress was because of their buyer protection so I guess I am not to worried about it because I feel like I can probably still get my money back if I need to. I am just incredibly frustrated and want to know what my sellers end game is!
[Android Head-Units] jeanbon12:
who is your seller ???
[Android Head-Units] junglizste:
If it's in escrow, he shouldn't get payment until you receive it and confirm everything is 100% as described, not when it's shipped.
[Android Head-Units] Drakey83:
His name is chuck liang, but luckily after yelling at him one last time and threatening to make a claim and take my money back he seems to have finally dropped my package off at the shipping place only 7 days after he promised me that he already had. Anyways, its making quick time I don't know if he did rush shipping or what, but he sent it on Friday and according to the tracking number its already in a hub that's only about 3 hours away from where I live. Im really busy this week but I will try to have a video posted by at least this weekend.
[Android Head-Units] Orisai:
First, let's hope he didn't drop a brick inside your package.

Good luck, and I'm looking forward to your video.
[Android Head-Units] toologic:
I also expect from this seller. He feeds me promises - "tomorow","soon", "after weekends" and so on. But once he sayd small true -

He extend Processing purchage up to 27 april 2014
[Android Head-Units] Drakey83:
So, I ran into another problem. I finally received my unit and brought it to Best Buy to get professionally installed. They did the installation but called me half way through with some "bad news". Apparently my unit came with no mounting holes and they said that there is know way that they know to install it. I looked at other pictures online and saw that my unit SHOULD have mounting holes where they don't but I thought that just maybe me and the people at Best Buy are missing something. Does anyone here know some kind of universal mounting kit that doesn't require mounting holes. If so can you send me a link?! I'm going to post pictures to show what I'm talking about.

Drakey83
[Android Head-Units] Nereth1:
Well to me, the item is not as described so theres problem 1.

I thought it came with brackets it would slide on? Thought I saw that in an image. If theirs any screws on it somewhere where you can secure it, that may be how it's done.

Having said that, it shouldn't be a huge job to open it up, remove those panels and drill some new holes. Just tell the seller first that they screwed up, and they can either send you a replacement with mounting holes or agree not to void your warranty as you will need to open it up and drill it.

It also probably wouldn't be a lot of work for someone with some basic equipment to bend up a set of brackets for it. If you are good with any CAD programs you could draw it up yourself, send it to a sheet metal place and probably get it done for the minimum purchase price (usually around 50 bucks here in Au, probably less over there in the US). Or you could DIY it with some vices and such if you are ok with a sketch job.
[Android Head-Units] Orisai:
I think he threw the unit he had for display purposes into a box, then he sent it to you in a hurry. That... or they have no in-factory QA at all.
[Android Head-Units] Zaphod-Beeblebrox:
What a comedy of errors this deal has been. I feel for ya Drakey.

As for drilling holes, they actually need to be tapped as well. Either that or you'll need to affix some type of nut on the inside.

My current installation required mounting a single din unit into a double din slot. The bracket I purchased was designed to mount the radio in the top half of the opening, but I wanted it at the bottom half. The holes didn't line up correctly, so rather than drilling holes in the plastic mounting brackets, I just got some 3m doublesided molding tape. The stuff is surprisingly solid.

http://www.3m.com/product/information/Scotch-Molding-Tape.html

It's readily available at Walmart, auto parts stores, etc.

I suspect you will have a similar situation. You will have a double din mounting kit with a large surface area that mates up to the radio. Use that tape to secure the brackets to the Radio. between the large surface area for tape mounting, and the friction forces that will want to hold the unit together once screwed into place, you'll have no trouble with it 'moving around' in the dash.
[Android Head-Units] toologic:
Drakey83

Do you ran the tests 4.2.2? Your overall impression? Errors and bugs?

Also
[Android Head-Units] Drakey83:
This guy is a joke, first he said that the unit is like this on purpose and that all universal double dins are like this and you are supposed to drill your own hole because I will need a specific set of holes based on my vehicles make and model. Which I know is a straight up lie and even proved it to him by sending him the stock image that clearly showed the mounting holes! the he said I could send in the HU and he could swap out the side panels (you know, the ones that were purposely hole-less) and replace them with ones with mounting holes but I would have to pay for shipping and wait for god knows how long. Then he told me that I could drill holes into it myself if I wanted to but if I was to take the unit apart, so that I could see where I was drilling so as to not screw up the mainboard, that I would void the warranty.

I then told him that none of these options were anywhere close to okay and that it looks like I am going to have to void the warranty because I'm not going to risk drilling into the board. I also told him that this is the worst shopping experience I have ever had in my life and that he was going to get a TERRIBLE score from me.

This molding tape seems like a great idea, i think ill try this before I void my warranty, Thanks alot!

But one little question what does "and the friction forces that will want to hold the unit together once screwed into place" mean? How would I screw into this if I only used tape?

Didn't really get a chance to test yet. I hooked it up long enough to install my navigation software and see that it was really version 4.2.2. I did get errors and I don't think its very stable but I will be able to test more once I jimmy rig it this weekend. Also, he sent me the exact line of BS word for word.
[Android Head-Units] Zaphod-Beeblebrox:
I just mean that in many cases the opening for the radio is pretty tight. By the time you slide the brackets and the radio in together, it may squeeze them together giving the radio very little room to move anyway.

However, if you've got enough surface area to put several square inches of that tape, I am pretty certain it'll be very solid.
[Android Head-Units] Orisai:
I wouldn't drill holes through the unit's case if I were you. Shreds of metal could drop on top of the mainboard, eventually leading to a short and an inevitable replacement.
[Android Head-Units] sciallo:
Sucky situation, I feel you....

First off, I wouldn't worry about "warranty", maybe test the unit as extensively as you can on the bench to make sure you don't have existing problems that would cause you to just want to send it back. If you do send it back or send it in to get fixed, replaced or whatever warranty or not you are paying for shipping to china. When I did it was almost $80 cheapest USPS option!!

So, really do you see yourself sending it in under warranty 3 months down the road?

The way I see it you have a few options:

- What I would lean toward is to request the seller to send you the two side pannels that have the tapped holes and brackets to make it right and replace those yourself (really not too hard to do. No cost to you, they better ship it DHL. Regular mail would take a month. Take that shipping time to bench test the unit and set it up the way you want it in the compfort of your desk/garage/workbench/whatever.

Or (assuming your $$ is still in escrow) unit not as advertised, settle for a partial refund to cover the cost of modifing/aggravation it and:

- Take it apart, drill holes where needed, use a riv-nut for thread, harbor freight has a set with a small assortment for cheap, pretty cool tool to have and does the trick nicely.

- If you really don't want to take it apart, try the suggestions above with tape and such or consider using the threaded hole(s) in the back (if you have any) to secure a bent sheet metal bracket to it.

Can't really think of anything else, if you do take it apart take the occasion to inspect all of it. ribbons, clips connectors etc. sorry to hear the aggravation continues. I hope it gets to be worth it :)
[Android Head-Units] Drakey83:
I decided to do the tape solution and it seems like its going to work well. I dropped a stinking screw for my dash in my dash so I cant complete my entire install until i can go to the store tomorrow, and then I will know for sure. Until then here is a quick test video that I did testing some things that were requested. Everything seems pretty good so far, but I guess I will see more tomorrow.

Looks like you were struggling with screen presses a few times. Was this just difficulty in trying to record while touching, or is the screen difficult to press?

Also, do you have any experience with any of the 800x480 res units? Can you tell any difference with the 1024 res? worth the hassle to get the nicer screen?
[Android Head-Units] Drakey83:
It was a combination of it being dark, being 4 in the morning, and filming while trying to navigate. I think the screen responds similarly to other capacitive screens I've used in the past. I never used a screen with that low of resolution so I can be much help, sorry. I will say the screen looks nice for the most part but a tad saturated. I'm going to look for an app to see if I can fix that with software.
[Android Head-Units] nE0sIghT:
Thanks for video, looks very good.

I saw torque in video, so BT adapter now controlled by android system?
[Android Head-Units] Drakey83:
I have torque plugged into it with a ODB2 USB plug. Now I am having a problem with it not connecting to gps, did you ever notice that?
[Android Head-Units] Orisai:
Drakey have you tried another launcher yet?

The UI in the default launcher is way too clogged for me, and I'd like something simpler, like Nova.
[Android Head-Units] nE0sIghT:
No, gps works fine for me
[Android Head-Units] Drakey83:
The stock launcher is garbage. I plan to put nova on it as soon as I have time (I'm currently in the middle of moving and finishing up my last year of collage) because I already bought it for my phone. I'll let you guys know how it works once I try it out.
[Android Head-Units] saidak:
I would try 2 things: 1) use another app (instead of sygic try igo or even google maps) for gps and 2) have you tried to manually set the port and baud for the device within the gps app, I know that most of them detect that automatically but some still allow manual setup and this would confirm if there is an issue with the device.

last but not least make sure that the gps satellite dongle is properly and tightly connected to the back of the HU.

good luck and let us know how it works out in the end.
[Android Head-Units] Nereth1:
Based on the music you played, were you able to discern if left and right channels are both getting to the speakers correctly? Not sure if I should assume that just because the left/right test works that the rest of it does. And does anyone else here have a good enough ear to know if the sound still seems to be coming through a high pass filter on that music?

Also, have you left the radio running long enough yet to know if it crashes the system?
