My steering wheel has a button labelled "Media" so I mapped that one to "Menu" (close enough). As for the push function of the knobs, I'll have to check tonight, though I believe they can be remapped under the "Extra Settings" menu. I like that this model has tons of physical buttons, but yeah, having a DVD slot seems fairly useless.

The instruction manual, which is barely in English, suggested that pushing volume would power down, which seems odd as there is a separate power button. I think I did press them a couple times but didn't see an effect. It's clear that these things are slapped together very quickly. That being said, the hardware seems sufficient to make for a snappy Android device. Miles ahead of the Pioneer AVIC F900BT I replaced.

Peter Chan posted a video of this hardware with the OUKU face.

I suspect that the software updates in this thread will work with your unit (it is capacitive right?). Especially if the root works as it suggests the file is the same. As for the hardware buttons, I would not worry about them, firstly that side of things does not reset even after a factory reset, and you can reassign them if they are lost.

My volume button has three functions, turning it alters volume, pressing it mutes the unit, and holding it puts the unit into some sort of standby state, however it's still pulling a whopping 1.4A in "idle", so it doesn't appear to be a real standby mode.

You should be able to set them to do whatever you want though.

I bought one from these guys, I sent payment via paypal but when I asked for the shipment details after a day they told me that the order got rejected.

"Thanks for your reply.

I've checked the order for you. Sorry to tell you that there was problem during quality inspection so the item was rejected and we're not pushing the supplier to provide another batch. It is expected to be ready tomorrow. Your understanding and patience will be highly appreciated.

Best regards,"

[Android Head-Units] patrickoneal:
As another poster stated, the payment to estorm also went to "light in the box", same as my payment to newdealestore2012. I was promised shipment by Thursday, delayed due to a "strike" by the warehouse workers. It's 2PM, Thursday, in China and Hong Kong. I've contacted them again for a tracking number. If I don't have one in the morning(EST), I'll be filing a claim on ebay, followed by a chargeback with my credit card if they drag their feet. So far, they've told me of a "strike", you of a "quality problem", and another poster of a delay for "serious quality inspection".

They're either selling something they don't have, or they're running a scam. My patience is at an end.
[Android Head-Units] KID52:
Light In The Box are a reputable company, they sell a huge volume of products.

I suspect they created the listings prematurely, and don't have the physical stock, but have placed an order with the factory. To be able to sell at the prices they are, the quantity they order must be huge.

Anyway, if anyone does cancel, although a more expensive option (very much so for those in the US that got free shipping), I can recommend Peter Chan completely.

My unit arrived in just 3 days via DHL (any idea what these eBay sellers will be using?), and Peter is more than happy to talk via Skype, albeit at strange times due to the time difference.
[Android Head-Units] jinny81:
light in the box

For all you guys feeling insecure ordering from light in the box - thats exactly who i got mine from.

My unit, although delayed a few days during pre shipment due to apparent checks to ensure it passes through customs, shipped out very fast over a single weekend by DHL to australia.

I cant find any fault with the unit physically. The software issues are another story but not with the seller, the manufacturer.

In hindsight i wouldnt have minded the more expensive model with the digital tv tuner, but i can always download/stream.
[Android Head-Units] KID52:
Orr get an external tuner and use the AUX in.

As mentioned a few posts back, it may even be possible to use a USB tuner which would have much better Android integration. Waiting on confirmation of this though.
[Android Head-Units] jinny81:
Yea, I was even thinking of the possibility of AUX in, a ps2 install instead better perhaps.

Hi,

i think all devices discussed in this thread have the same hardware.

i found an offer on aliexpress where you can choose one of three different front-panels

[Android Head-Units] chris.r.r:
I'm also waiting for my unit - ordered from Peter Chan. He told me twice that he sent the parcel at Monday, but according to DHL tracking they haven't picked up the parcel yet.

Although I'm convinced that Peter Chan is a honest and correct guy, there is something wrong. Could it be that the unit is currently not available from the manufacturer and this causes the delay for us all?
[Android Head-Units] KID52:
Yes, this was confirmed a few posts ago.

The confusion is that some listings state 1.2GHz, but really they are 1GHz the same.

I think the link you gave just further confirms that these are indeed identical units.
[Android Head-Units] KID52:
If he gave you a tracking number that means at the very least that the shipment has been paid for. Perhaps DHL are slacking.

Honestly I would not worry.
[Android Head-Units] :
sry, didn't see.

I also noticed that in sime listings there is a screen resolution of 1024x600.

Does anybody have further infos on this?

Is this resolution for all devices?
[Android Head-Units] KID52:
No, they have 800 x 480.

I asked about the 1024 x 600 resolution and apparently it is only for versions with larger screens, I think they mentioned VW style units having such screens.

so i flashed 2.7.4 and I ended up with a 'UI Unauthorized...' so I just flashed 2.6.96. I did not get all the gapps back, but I got play store back and was able to log in. thanks a bunch.
[Android Head-Units] Cavalier Condorelli:
Update Torque, here is the change log related to the storage problem issue:

Changes in 1.8.32

=============

* Improved the touch responsiveness on the main start screen

* Added option to delay bluetooth connection (in-dash settings added) for when the app starts on boot (and bluetooth hasn’t started up yet)

* Remove several annoying ‘toast’(pop-up) messages about not being able to see the adapter when you are not in the app

* Fix an issue where a dialog about the SD card not being present would popup before the wait for the SD Card had completed (start on boot issue, where the SD Card wasn’t mounted yet)

* USB serial driver updates to fix a data corruption bug for devices using the USB OBD2 adapters (can now reach 200PIDs/sec on CANBUS 500k systems)

* Add a warning for another set of clone adapters with duplicate /shared bluetooth hardware addresses (this will cause connectivity issues when 2 adapters of the same type are in range of each other)

* Added pure Methanol fuel type to the fuel selection GUI

* Updates to AIDL api required for new bluetooth plugin

* Equation editor ‘test’ function no longer dependant on being connected to a vehicle ECU (where a PID is not needed)

* Improved the validation for the webserver upload settings (realtime uploads) where some accidental spaces were causing issues

* Added automatic support for PLX iMFD expandable sensor modules

[Android Head-Units] PsychoMcSatan:
I haven't tested everything, but it works for my needs. I don't use the DVD at all.

I'm still waiting for an updated MCU that ends in 7-10-2501 so that I can get my knobs working in the right direction, but other than that, my radio is doing everything I need it to do.
[Android Head-Units] booba5185:
So now that I finally have Torque Pro working like it should, I'm trying to speed up my boot time. Startup manager says it boots in 30 seconds. I've disabled boot animations, and other build.prop edits, I used startup manager to stop programs from loading, etc.

I was wondering if I could set up the shut down delay for say 2-3 hours, so if I go back out to the car and start it up within that time frame it'd basically be in standby and be readily available? Do the amps shut down when the head unit is in shutdown delay? If I were to do this, does the MCU and Android get out of sync on audio again (requiring the reset or exiting a stock app)? Thanks guys.
[Android Head-Units] KID52:
It was actually a really hard decision.

Hands down the design of the first one you linked to is best, however I went for the other one you linked to for a few reasons.

It was cheaper

I prefer the volume knob to buttons, although the design is not as good

It advertises DVR and Bluetooth OBD2 functionality (whether they work or not is another story)

TV in the car is of no interest to me

The ability to change button light colours is nice
[Android Head-Units] PsychoMcSatan:
I've installed a device that maintains ACC power for set time after shutting off ignition so I have some experience with a couple issues. The main one is when you crank the engine again, voltage drops (in most except high end cars) which does seem to get MCU and Android out of sync. This makes it almost impossible to give your media app ability to play sound till the unit is reset.

Generally I'd say that these units don't respond well to voltage drops. Anything from just the screen blanking out for a sec to a full reboot of the unit. After I replaced the battery in my car it seemed better, but I'd get the sound issues every few restarts.

So my solution was this thing:

http://www.ebay.com/itm/DC-DC-Stabilizer-I-P-8-40V-Regulate-to-12V-10A-120W-/250888204291?ssPageName=ADME:L:eek:C:US:3160

Works like a charm. I think another guy on this thread used one of those big audio capacitors that prevent your subwoofer from dimming your headlights. However, both these solutions will always draw some parasitic current so I ended up installing my eBay thingy behind a relay so it doesn't draw power when the car is off.

Another issue that I'm still troubleshooting is that when I walk away from my still powered on radio and I get out of bluetooth range, my phone doesn't automatically reconnect when I come back to my car. Though I think this could be a phone issue.
[Android Head-Units] booba5185:
I gotcha, so that is on the list of things to buy, my wife would HATE resetting the unit most of the time we started the car. I'll just put the remote wire on a relay controlled by the ACC wire so the amps don't stay on with head unit.

Also, other than using the color.apk app, is there a way to see if I have the color changing LEDs? I've tried the color app but it didn't do anything. I have 7.4 firmware, and my MCU is 4.2.13, IIRC. Maybe I'm using the color app incorrectly? I just touch the color I want the LEDs to be, right?
[Android Head-Units] PsychoMcSatan:
I think it's only the two knob units that included the LEDs necessary for colour change. If that color.apk does nothing, my guess is that you're out of luck. Actually, I think in one of the more recent system images there was a setting in "Extra Settings" that turned my LEDs bright red or blue. Not sure why it was in there since color.apk allowed for fine-tuning of colour, but may be worth looking for.
[Android Head-Units] booba5185:
Been there, tried that. Seeing those settings in extra settings is what got me looking into the color changes. I guess I'll have to swap out the LEDs if I want this to happen. Has anyone actually done it? I've seen mention of doing it, but I haven't seen it actually done. Another thing I was wondering...overclocking...any point to it in these? I was thinking about using some thermal epoxy to put a small heatsink on the processor.
[Android Head-Units] digitaldr:
Trying to figure out how to wire the voltage stabilizer- do you connect the input positive (red) wire to the permanent live 12v and the output positive to the stereo and the two negative wires both to the ground wire on the iso harness. Then does the relay go on the red input wire using the 12v switched to control it? I noticed some cheaper lower rated ones on ebay - would these be ok? Also does it get hot and if so should it be sited anywhere in particular?

Thanks
[Android Head-Units] cat2115:
Could someone help me. Not sure what happen but when playing YouTube and in like a mintue and stop play. I had to press play again then it play. A mintue later it stop again. Never had this problem before.

It's not just YouTube even when using gps the screen flicker.

Now time work correctly with latest mcu. After setting zone time, I need to check auto update.
[Android Head-Units] PsychoMcSatan:
Yeah, that's how mine's wired. Though you also want to wire the other relay output straight to the radio (so it keeps 12V to the radio when ACC is off) and I put a diode on the stabilizer's output so it doesn't see that 12V when ACC is off.

I measured it at 20mA with no load so a relay maybe isn't necessary if you drive a lot. Doesn't seem to get warm so it's probably fairly safe, but it is straight from China with no warranty so a fuse in front of it wouldn't hurt.

I was thinking of those lower rated ones as well. The most I've seen the radio draw when I cranked the volume was a little over 3 amps, but I got the 10A one since that's what the radio is rated at.
[Android Head-Units] Cebulon48:
Hey,

reference the power drops, when the car is started:

Isn't it good enough to buffer the Voltage with a Capacitive (which is charged from ACC on) and supplies the necessary power during short standbys or during car start?

Has to have a resistor and/or diod to??

Has someone tried that?

[Android Head-Units] jpapadami:
Congrats on the new unit. The unit that I have (with horizontal buttons at the bottom) also supports DVR, so I bet yours will too. Let us know when you get it and how the Bluetooth ODB2 support works out. Also interested if you can connect other bluetooth devices. If the unit is able to work with bluetooth ODB2 there shouldn't be any hardware restrictions.
[Android Head-Units] KID52:
I think the listing is rather unclear as to what the DVR part is.

The listing text "supports DVR" is rather vague wording, and although hopeful of an interesting feature, I suspect all they mean is you can connect the output from your DVR to the head unit.

May I ask how this function works on your unit, and exactly what it does?

Is it just a confusing way of writing the unit has a video input, or is there something more?
[Android Head-Units] jpapadami:
My unit has two sets of A/V cables and on one of them there is a dedicated DVR RCA jack in the back and I believe that there is also a dedicated wire, but not 100% sure as I don't remember how it was when installing the stereo. I know that the DVR function is used for recording videos while driving. If you have ever seen those "Russian car crashes" videos on youtube, they all use DVR. From my understanding they use it for insurance and police traffic issues to prove who was at fault during an incident.

I'm not sure if the unit has a chip inside for digital recording, do you need another hardware unit in conjunction with the stereo (besides the front camera that is needed for recording), etc... I personally have never used it and don't really see the need for it, so I can't comment much on DVR.
[Android Head-Units] Zittermann:
Is there any working USB LTE dongle?
[Android Head-Units] anpo:
I gotta have one of those :)

Is the diode connected like this? www dropbox com/s/mwpf0o0k0acc2vg/dc-dc-reg.png (sorry still waiting to be trusted with links and attachments here)

I suppose that the diode has to be rated for 10 amp as well?
[Android Head-Units] PsychoMcSatan:
Another user on this thread mentioned that he'd done that successfully, but I'd read discussions about my previous radio that it was hit and miss, maybe due to too small a capacitor. You'd probably need a fairly big one, like the >1 farad ones that are the size of a can of beer. Search eBay for "audio capacitor". I read a story about them cracking open and spewing black goop into your car so I tried out the voltage regulator first.

Nice diagram. I could have used that before I started, but that looks to be exactly how I've got mine wired. However, I just realized that if you're relying on the radio software to stay powered on, your ACC will drop and the relay switching could be enough of a power interruption to cause issues (I have a device that keeps ACC on). So you might want to connect the battery straight to the radio behind another diode placed before the junction with the regulator output. I've attached an updated version of your diagram.

As far as the diode rating, yes, 10A or more to be safe. Check what the voltage drop is as my diode drops the voltage to 11.4V which so far seems fine.

And an extra 10A fuse wouldn't hurt.

EDIT: Hmmm... just looking at the updated diagram I realized something. I've heard that some cars will drop ACC when cranking the engine so if that's the case, this circuit will not work. Another option that I had considered was simply putting a toggle switch instead of a relay. Then you'd just flip the switch before (re)starting your car. And again, all this switching is simply to stop the 20mA draw that the regulator would pull when your car is off. Probably not even worth considering if you drive regularly. (I'm just a groceries and occasional road trips kind of driver)

May have Fried board

So I am not entirely sure what has happened but, I think my unit is toast. I have not modified the MCU, the only thing that has been done is that it is rooted. I was using my head unit perfectly fine when my wife got out of the car and i started to drive away, I received static on the screen and through the speakers. Now my first response (possibly the wrong one) was to reset the unit. I tried just using the face plate power button to cycle the unit, which did not work. I parked my car and turned the ignition off and back on. It booted up but did not get through the loading screen before displaying the static again. I let it sit off for several minutes and tried booting again, this time it made it through the loading screen but then within 2-3 minutes static again. now the unit will not boot at all, no loading screen and no signs of life except for the radio in the background (Which isn't really signs of life) and the back light behind the screen and face plate button lights.

Now unfortunately I have done the external mic modification, so any warranty that may have been applicable is now long gone. I pulled the unit apart to check for any loose chips, blown caps, or blown IC's. none of which are glaringly obvious. I have the no-dvd 7" model, but the board looks identical to any that i have seen posted here (slight variances)

Not that i wish this misfortune on anyone else, but i do sincerely hope that someone has had this problem before and can tell me that i did not just burn up 460$. I am willing to try any suggestions that any of you may have, please let me know. Thank you.

battery drain

I am experiencing a battery drain. I haven't used my car past 3-4 days. Is there a way to solve this. I ha\ve been trying to read this forum, suprised there not so many users with the same issue.

I have been reading about sleep and non sleep mode, whats that about? Extra option in the firmware? And does it works?
[Android Head-Units] PsychoMcSatan:
I see about 15mA being drawn by my unit when the car is off.

I do recall earlier on in the thread another user seeing much higher draw. I can't find the specific posts, but I seem to recall that the lights on his wifi dongle did not shut off, indicating that the unit was not completely powering off and maybe in some sort of semi-powered sleep state.

Do you see any LEDs still on and does the unit feel warm even after it's been off for a while?

Only way to know for sure is to measure your current draw with a multimeter.
