Of the 3 generic double din models listed, I am seriously thinking about #2 or #3. Really like #3 due to the dedicated GPS button. Are all 3 of these units the same with different control setups? I have a 2000 Jetta I want to put one of these into.

Will this work with Waze GPS?

Uhmm, careful, that is a Toyota version. Way wider than standard 2 din. Nice it has a 8 inch screen, but will NOT fit standard 2 din opening...

Thanks sciallo. I've been following your posts in the ouku, an-21u, and wd8801 threads. appreciate all your work.
I was completely ready to pull the trigger on a universal WD8801, as the universal ones I've seen have abandoned the DVD, giving larger screen size, but still retain a decent volume knob and the requisite android buttons:
http://www.aliexpress.com/item/Quad...itive-touch-screen-1024-600HD/1644030858.html

I simply hate the look of the interface, and the few people who have one so far are experiencing issues.

I found a nice one that looks to be an AN-21U alternative:
http://www.ebay.com/itm/7-INCH-Andr...Video_In_Dash_Units_w_GPS&hash=item3a8e81e95d

But it's 800X480, not 1024X600. I was just dissapointed enough in the Ouku resolution, that I thought the bump up would be worth scouring variations for that perfect combination :)


Anyone have any experience with both the 800 and 1024 screens? Is it worth pursuing?

Don't mean to thread hi-jack. My interest is really in this particular unit, just looking for the exact variation.

Thanks,

I am getting ready to buy something again. I can tell you even with the short time of playing with mine, if you want to use many of the android apps, you are going to want to get something with a 1024x600 screen. I found a few apps that were not usable, because you could not see all the buttons on the GUI to move to the next. If I recall Google Voice was one of these.

I asked Keylo on an update on the 1024x600 the other day, and did not get a response. I know a few weeks ago, they were having problems with their software on it, and were working those bugs out. While I really like this radio and its project, I will not buy something without a 1024x600 screen. Really would love a 1280x800.... but think Im dreaming. :)

The UI on the first link actually looks pretty decent and not half assed. But i'd be wary of buying it, it claims to be a pure Android 4.2.2 unit, but in all the screenshots and the description itself, it shows it's an Android 4.0.4 unit. The quadcore is nice however.

I've been speaking with Keylo about the 1024x600 and the last I was told is that MAYBE sometime around July but of course that is variable and she couldn't promise anything.

I've decided to try with the lower resolution screen that you had, webdude, and see how I like it. If I really like the unit and the 1024x600 comes available I'll sell the lower resolution one and get the 1024 model. I'm hoping for a good unit as every bit of communication with Keylo has been great so far. No reason to expect anything less. I imagine my unit will get shipped relatively soon so I'll have more info to report in the coming weeks!

This appears to be the same unit discussed in this thread, but claims to be 1024 x 600

http://www.aliexpress.com/item/Shar...-1024X600-3G-wifi-dual-core-1/1727312607.html

If it had the DVD removed (and thus a slightly larger screen), I'd be all over it.

You can read up about that unit in this thread:

http://forum.xda-developers.com/showthread.php?t=2618348

I think it initially was released as a 4.04 device. An update to 4.2 was promised, and possibly they've retooled the listings to accommodate.
It is hoped that the 4.2 firmware fixes a lot of issues, as the few people who got early devices have had many issues.

I absolutely agree with webdude. If you can, buy 1024x600. For instance with 800x480 I cannot use google chrome because the sign in button is too low on the screen and cannot click it. The regular browser that comes with the unit works flawlessly though. If I could, I would just get the HD too, but Keylo told me the same as webdude, they are having problems with the software.

I still have not been able to dedicate time to cracking the bootloader, (which, btw I have no idea how to ..). If I make any progress, I will post it here. I do not expect it to be different from regular RK3066 chips, so I will start by just comparing with a tablet RK3066.
Has any of the owners had an update of the MCU ?

The other day, the unit took longer than usual to boot and all apps were wiped out. Then I realized that the MCU version was of 4-4-2014. I noticed no real changes, only the bluetooth name changed from KGL07 to Car Kit. The rest seems to be identical.

I could live with the lower screen resolution. Keeping this device in perspective, its a smart car radio. It does GPS, can integrate with my calendar (I'm a consultant) and lets me listen to music or other internet sources of content. I will spend very little time surfing the internet with chrome, or watching movies, or playing angry birds. For me, GPS, mail/calendar, bluetooth, and radio are the most important things.

Keeping that in mind, there are units on ebay that I have not seen discussed here. Such as Android-4-1-2-CPU-Double-Din-3G-Wifi-Car-GPS-Nav-Mp3-DVD-Stereo-BT-Indash-RDS-SD- (I cant post links yet). Dual core 1Ghz A9 1G Ram/8G internal. I like the button placement and volume knobs much more than other units I have seen on ebay. I wanted to buy the unit we're discussing from HuiFei, however their alibaba single unit price is $460, and their ali-express sellers dont take paypal, and aliexpress doesnt allow me to use my business card for payment. So I have no way to purchase one of these units for a fair price or in a less risky way. (which is unfortunate). Thoughts on the ebay units available?

I believe the unit you're talking about is the one I currently have (two knobs+two columns of buttons), the dual core is a AN-21 U variant
http://forum.xda-developers.com/showthread.php?t=2528349
There is also a cheaper single core android 2.3 version known as the OUKU
http://forum.xda-developers.com/showthread.php?t=2110546

There is quite a few different ones. Most have made it to the wiki
http://forum.xda-developers.com/wiki/Generic_Android_Head_Unit
And have their own wiki pages linked from there.

Incidentally, I see the unit discussed here isn't listed there... I have been slacking, my time has become very scarce lately, but if nobody beats me to it I will update the wiki pages as soon as I can.

Hi sciallo, you can take the first post of the thread ( I tried to summarize everything that has been said here) or take the dedicated wikipage that webdude created for HuiFei.


Regarding the unit, I am so far very happy. Everything seems to work properly. It is fast and smooth and you can stream radio, use gps, a2DP, store music in a micro SD card, check mail, and many other apps without any problem. Thus, for a car head unit is quite perfect to me although I would like to be able to use any app in case I felt like (higher resolution would be better). The only things that I am missing are:

- auto-brightness--> this is a must in any head unit. (I have figured out an alternative using Tasker, but it will never be as adaptive as auto-birghtness. It cannot handle tunnels, parkings, etc).
- faster boot time

I use mine in a very similar way .. maybe even less so. GPS and media are all I really care about. I primarily use waze for GPS, and just want the higher rest for that. Using G-Music and others would be nice, but I have a 32gb SD card that I just stuff a ton of music on and forget about it ;)

Would be nice to set up some pod-casting managers to auto-download and listen to some podcasts occasionally.

The only app problem I ran into with 800x480 was swiftkey. coudn't hit the license agreement and had to find another keyboard (this was on my ouko 2.3 unit). The default keyboard was a real ***** with that resistive screen. Needed something with bigger keys.

I ran into several apps like this. Which is why I am hunting for a 1024 x 600 screen. As phone screens get higher resolution, so will future apps. This as a radio is all good and grand right now, but if I cant use it in a year or two down the road, because all the apps GUI have been updated to be non-usable, then I am going to be highly upset.

I have a lead on a Dual Core A9 - 1.4 Ghz, 1 GB Ram, 8GB Memory 1024 x 600, and being told unlocked bootloader. Waiting for more information and specialty models, but could be a good alternative.

Also one thing that might be useful to the owners of this radio is to request to Kernel Source from Keylo. They are legally required to release under the Android License Agreement. This could help modify and build custom recoveries to get around the locked bootloader.

It would certainly be nice to have this, but just to clarify, kernel source, bootloader issues, and custom recoveries are all separate, and not always related issues. I think I saw earlier in this thread where you managed to get a custom recovery loaded, but couldn't access the partitions. Not sure kernel source will solve that.

From a more deeper development perspective, even with an unlocked bootloader, and custom kernels, without source code for the interface between the MCU and the various system apps (radio, media player, etc), we will have difficulty do much more than themeing/tweaking the system apps.

and BTW, it's not the Android License that requires source. Android is published under a modified apache license. It's not viral. You can close source your code at any time. the GNU license by which the linux kernel is used is viral and requires source code distribution.

Sorry if I'm coming across as 'that guy'. Don't mean to :)

Love having you and Webdude talking this stuff through - I don't understand it all but learning a lot from you both. As my unit is on the way I'm primarily interested in reducing the boot time of the unit and removing anything that is unnecessary. Also want to be able to load up the most current version of Google Maps and download some offline maps. I need to re-read the thread but if anyone has quick info on either of these it would be much appreciated!

How is this head unit sound quality?
I'm going to power 4 x Kicker 40CS654 with it.
How this devices play in comparison with regular Pioneers or Kenwoods, etc. ?
Thanks a lot.

Most of the time you can write a kernel module to force you to have access to the partitions, even if the bootloader is locked. This only is good in recovery mode, but does help.

And while you are correct without the MCU, we cant do a fully custom rom, But the ability to De-Odexed, Zip Align, add init.d support etc can make this radio really shine. Also should be able to tweak none radio programs, decrease boot time, etc. Everything a "custom" could make nice.
