I was also interested to hear opinions and thoughts about this unit. The only thing is that does the unit always need to have the Android box for the stereo to work? Probably not, so it would be pretty irritating to find a place in your car to hold this box. Maybe in the glove box. Specs seems nice only due to the quad core and a little higher screen resolution, but that's it. I would rather by a car stereo and media player box separately then having them in one like this unit.

Here's a thread in xda to read about it

Radio Widget

My unit (Infidini AN-21U) came with 2.7.38 installed. Apparently there is no radio and/or AUX widget available - does anybody here know what to do to add these? Does 2.8.3 have a radio or AUX widget? Does it require a homescreen APK from an older build? Perhaps an old Radio APK? I'm going to try 2.8.3 tonight.

sometimes it 2 files, 3 files 5 files. ALL files in the folder have to be in the root of the sd card. yes you can downgrade just the same
[Android Head-Units] kaween:
Yup. But whatever you do, DO NOT INTERRUPT THE FLASH. As "Siny" says (by the way, what are you doing with a picture of MY cat ? :) ), it can be 2, 3 or more files : you don't have to select, the flash routine will do what it has to do automatically.

But please, please, do not shut down the unit because you think it is stuck or whatever because once you screw up completly by powering it down prematurely, you MAY/WILL end up with a bricked unit.
[Android Head-Units] gyaku_setsu:
Luckily I haven't had to delve too deep in to it, but I know any signals sent to address 56 are meant for the radio. Check out the ROSS-TECH website for more addresses, but 56 is the main one you'll be looking for. I know there are a couple blogs out there about CAN sniffing. http://hackaday.com/2011/03/08/can-sniffing-for-steering-wheel-button-presses/ is a good place to start. I considered doing this when I got a Parrot ASTEROID Smart, but then I realized their proprietary interface box actually worked with my VW (it just had to be updated), then I stopped looking.

From my experience, I had tried to disable address 56-RADIO in the CAN Controller module after connecting an aftermarket head unit to stop it from throwing an error code all the time, but when it is disabled, all functionality is also lost. So even if the address doesn't show up as connected to anything, it will still allow signals to be sent to/from that address... even though it is in a permanent error state...

So yeah, CAN is a mess and shouldn't work, but it does somehow.

Also, keep in mind that unless you can get some sort of device that can convert CAN signals to a HID Keyboard signal, you'll be SOL unless you can figure out how these units communicate with their proprietary CAN decoder boxes (which, from what I know, work pretty well... never heard anyone complain about them). http://atomic-cactus.com/2013/03/26...steering-wheel-controls-using-arduino-part-1/ is the only person I have seen that has tried to make a CAN to USB HID Keyboard device.
[Android Head-Units] kaween:
Heh, the design looks a bit Parrot-Smart-like. Odd that the link is called a "8 inch" device where the description clearly states it is a 7" unit. :)

And to be honest, I'm not too keen about that. I'm probably too old for this kind of design, but I really like "real" buttons on a unit. Even though I have a fully working SWC, I find working with a non-tactile-feedback touchbuttons/surface iffy at best, dangerous at worst when trying to operate such a device while driving. But yes, I'm probably just old fashioned. (I even repair old tube radios as a hobby .... no joke).

There's a thread running on these devices, but so far no real usable info as only one person has received his unit. So sit back and wait.

However, it would be nice to compare "dream specs", or better said, what would you like to see on a future unit ?

In my case :

1) fully rooted and unlocked. (=the saving grace of the Huifei in my book), with a complete, non-cut down droid versoin. CWM capable. (not possible on AN21, not likely to happen)

2) Real sleep mode. Instant wakeup, or wakeup within 2 seconds max. (well, the fast radio boot of the AN21 is nice, but it would be nicer to have a "boot once, sleep afterwards" device)

3) external mic, OBD-capable OBD, high power wifi. (basically possible on the AN now)

4) Higher resolution screen. Oled please ? (hey, it's a wishlist !) (..... dreaming)

5) FULL Radiotext support. The AN21 is .... nearly there, but not quite. Most android units have NO Radiotext what so ever. (should be possible as any low cost phone can do this)

6) lock screen functionality (well, that would be part of "1" too I guess)

7) a near borderless design fitting a "Honda" type clearance ( 172x98) with 7" screen. No drive needed. Hardware buttons for volume, power, Navi, Source. Programmable please.

8) Audio BT support with full support for info-text (song name, artist, cover art) (.... is technically possible, not seen on any unit so far)

9) a user definable GALA/SDVC function. (possible on the AN21 in non-user definable version, available on the Huifei thanks to some smart guys on this forum)

10) 100% compatibility with ALL existing GPS software. (this seems to remain a problem on ALL droid units so far !!!)

.... for not more than 300 USD. Till something like that comes along, the AN21 will have to do in my car. :laugh:

The idea of having the biggest part of the android function in a sepperate box like with this Newsmy is nice. It allows mounting the "crash-capable" box in another location if the 2din mounting space would prove to be a temperature trap or whatever. Also, if standarized (still dreaming), it would be the ultimate "upgrade the easy way" platform.
[Android Head-Units] gyaku_setsu:
That thing looks neat, but that description page... what a mess! I mean, the layout looks fine, but what exactly are they selling here? ...and is that a firewire port on the back? Why are there permanent buttons on the side AND soft buttons on the screen? Honestly, looks like a first attempt at something awesome, but a really bad execution.

Keeps saying there is a DVD drive, too, even though there clearly is not.

I'll stick with the AN21U I ordered that is taking 3 weeks to ship and has a similar form-factor made for my vehicle.
[Android Head-Units] kaween:
The "firewire port" is the connector to the android-breakout box. (yes, the android part is not inside this device, it's an external box).

I'm sadened to read the first adopter of this unit has ran into some .... pretty incomprehensable problems. (http://xdaforums.com/android/general/4-4-2-kitkat-head-unit-newsmy-carpad-t2865525/page8 )

I sure hope it still turns out fine in the end ...
[Android Head-Units] gyaku_setsu:
Anyone know what kind of DAC is in these units?

I'm just curious if I should bother downsampling 24-bit audio, or if the unit can handle it.
[Android Head-Units] jpapadami:

[Android Head-Units] wanxu:
Thanks guys! I did it as you say.

Now I'm on 2.8.2 (1024x600). The unit seems to work exactly the same as before.

The UI has changed from this (big widgets):

to this (dock with small icons):

Radio interface has also changed but kept all my stations.

One more question. the MCU remains the same (4.3.7-22-10-E50201). Do I need to update it? I downloaded a file someone posted ago with new MCUs from 2.8.3 that has one file I think is the one for me: 4.3.9-22-10-E50201.

Edit: I have the red warning. I'll see how to get rid of it...
[Android Head-Units] mtresk:
Update mcu by choosing your car model in additional settings.
[Android Head-Units] kaween:
In regards to your MCU upgrade question : "if it ain't broken, don't try to fix it".

Unless you have a serious issue with the MCU (buttons not working/EQ not working/...) and/or you have a backup of your currect MCU, I'd not touch it. I got in world of hurt because my seller pushed me an MCU that was not correct for my unit, and it took 3 months or so till I found a new version that worked correctly !
[Android Head-Units] wanxu:
Ok, so I won't update then.... The unit seems to work fine.

By the way, com.tw.service_a5a4[no+red+ui,+2.7.39] is compatible with 2.8.x versions to get rid of Unauthorized UI message?
[Android Head-Units] Miwer:
Well, the sound processor on the board is analogue inputs, so I'm guessing the DAC is internal in the MST786 cpu, but I cannot find any info or datasheets on this chip.

I don't have the board in my hands right now, so I can only guess by looking at pictures and by the datasheet of the onboard sound processor.
[Android Head-Units] wanxu:
I've read in 4pda (google translator :P) that all firmwares 2.8.x have been removed because are from RedPower (a russian brand, there's a forum with the firmwares but you must be registered http://forum.redpower.su/proshivki-obnovleniya-f66/proshivki-obnovleniya-dlya-180-serii-t5974.html).

Music player gives short errror readings

Anyone had problem with the Native Music player. When i play music from USB .wma or mp3 the player sounds like "bits" are missing now and then. High pitched squeek for 0.5s and the music continues normally (about 20times/h). Very annoying. Running system version 2.7.39 and MCU 4.3.8.1-3-10-040201. Non rooted.

Have you tried baidu root 2.4.6?

I'm a little ashamed but I have another problem. I went back to 2.7.38 and everything is okay but the unit buttons. They don't work at all. Steering wheel buttons work perfect, the screen is showing AC and OPS, so the MCU is okay, but the unit buttons are not detected. Any idea?

I tried going to Extra Settings, Panel key, but it doesn't work. Maybe I'm doing it wrong, but I don't think so.
[Android Head-Units] jpapadami:
I registered and entered the RedPower 180 Series forum. Unfortunately, to enter the forum where the firmware links are kept, you need to become part of a "Redpower" family group and there are prerequisites (see text in red in the forum thread). Crappy.

No i don't tried this version ... i download and try tomorrow :good:

For your problem you've get in extra setting a line call "model choose", try the vw or the rav4, you have 5 or 6 model those change buttons setting,

after that if the bluetooth doesn't work you have to uncheck bc6 in option to connect phone ;)

Ok, that's what I can say:

- I was with firmware V2.7.38_20140811_1024X600_SYSTEM_ZC_10_1_K_DZSJ 9002

- Buttons were not working (SWC was working fine)

- I flashed V2.8.2_20140921_1024X600__KED2_RP and buttons started to work back but I had the red warining about "UI not authorized"

- I made root with baidu 2.4.6 (lost every reboot) and changed in /system/app (I think) file com.tw.service_a5a4 with the one I downloaded here: com.tw.service_a5a4[no+red+ui,+2.7.39]

I have this deck working almost the way I want it. There is only one problem that is bugging the crap out of me. I have the delay timer set for 30 minutes.. so when I run into a store I can come back and just have the deck resume. This only actually happens once in a while. Most of the time when I start my car the deck reboots completely! I can turn the key to ON and it resumes fine.. but when I crank the engine the deck will reboot most of the time (not all the time). This obviously isn't an ACC wire issue as this gets cut off anyways and the deck is suppose to resume when you turn it back on (which it does, except when cranking the engine). I probably have a voltage drop when I start my car. I read earlier in this thread someone using this:

http://www.ebay.com/itm/250888204291?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT

Has anyone had any experience using one of these with their deck? Did it work? Do you think this would resolve my deck reboot issue? Is there an alternative solution for the issue I am having?

If I can solve this issue of the deck rebooting on engine crank.. It would make my day! I've been dealing with it for quite some time, and it gets really annoying!

Thanks for any input!
[Android Head-Units] wanxu:
I have the exact same problem. I asked the manufacturer and they told me "it was normal", but it's really annoying. Let's see if anyone tryed it.
[Android Head-Units] gyaku_setsu:
I think you're spot-on with the voltage drop idea. My external amp does something similar by going in to a "protect" mode when the engine cranks so that it doesn't pull current when the voltage is too low. That stablizer might work, but the tried and true method in the car audio world would be to add a capacitor to the power line.

Something like this would definitely solve it: http://www.ebay.com/itm/New-VM-Audi...ar_Audio_Video_Capacitors&hash=item5af866f37d

They're like a big battery that recharges constantly. As long as your ACC wire isn't being intermitent with its 12v supply, this will keep the main power steady and constant. I haven't personally used one yet because my problem is not noticeable unless I have the radio on while the car is in ACC mode and then crank the engine (a rare scenario in my life), but keep it in mind. It is a cheap and easy fix, and if nothing else, it'll prolong the life of your unit by keeping the voltage regulated and constant; voltage variation can mess with power supplies and shorten their lives over time.

These things are kinda big, though... so make sure you have a place to put it.
[Android Head-Units] kaween:
Of course he is. And I can tell you now : that cap won't work to get rid of the reboot.

I'm/was quite active in other forums which coped with the reboot-during-crank-caused-by-drop. No cap EVER solved this. _NEVER_. Some of my German friends even tried caps twice that big, did not help. We ran a couple of calculations on it and it was quite impossible to solve this with a Cap, and these calculations were confirmed by all failed experiments and these "power caps".

Look at post #4827 for all the info you need.

I'm not going to repeat myself : if you want to "bridge the crank", use my solution that I proposed in #4827 involving a pico-ups 120 and a small SLA battery.

That solutions works. I use it daily. Material-wise it will cost you 50USD or something.

Root: The Wiki is

extremely

outdated. With 2.7.38 and up, you need to install Baidu Root 2.4.6 Russian version. It's been posted several times in the last few pages of this thread. You can also search this thread for Baidu. Install Baidu, root it, reboot, install SuperSU, reboot, uninstall Baidu (it's a sketchy Chinese app that can install random apps at will among other things).

Remote: you need an IR receiver. Typically they use a 2.5mm or 3.5mm headphone style jack. If the headunit does not have a port for a 2.5mm or 3.5mm headphone type jack labeled IR or REMOTE, the remote may never work

Microphone: pretty much the same as remote. If it doesn't have external wiring for it, you are SOL unless you disassemble your unit and desolder the two internal mic wires and install a jack or pigtail in the back of the headunit.
[Android Head-Units] gyaku_setsu:
Cool, thanks. I will contact the seller about the IR input and the external mic problems.

I tried baidu root once, but it was a different version and—as you mentioned—it was super sketchy and tried to install crapware on my device, so I stopped trying. :silly:

[Android Head-Units] PsychoMcSatan:
Yeah, I installed one of these a while ago and haven't had a problem since. It was long enough ago that I can't seem to remember exactly why I added a couple relays into the circuit, but I believe it was due to a bit of a current draw so I isolated power when the engine wasn't running. I can't remember how much current, but I don't think it was a lot. I don't drive regularly so battery drain could be an issue for me.

I'll see if I can find the circuit diagrams I drew up for myself.
[Android Head-Units] storm83:
Thank you for that. I've been trying to look up solutions for this and it's hard to find a clear cut answer on this subject because everyone's setup is so different. I've tried a cap and that didn't do anything.. although it wasn't nearly as large as the one mentioned. The pico ups and battery idea is a great one as well... but I don't know if I have enough space to add an extra battery like that. I would much rather go for the stabilizer if it might work. I've been holding off on getting one until I got some input on it. I might just go ahead and order one and just try that out for now and hope it works... cause that would be awesome!
