Regarding your post #860 - many thanks for that! :good:

What is the technical difference between the regular and the OEM app?

Thanks
[MTCB Android Head Units Q&A] ndbssie:
Lock screen is an option i really want/need.

Tried it with tasker with System Event/ Device Boot to accomplish this.

When i turn off ignition and after a while i turn it on again the HU is started and also Tasker is executed.

So far so good.

But when i turn off the HU by pushing the power-button (i can see Tasker is shutdown before the HU is) and turn it on again Tasker is not executed.

How can i make tasker run after poweroff/on by the push button?

An interesting information : All the HUIFEI units with display size 7" and 8" are now available in an upgraded version with 1024 x 600 High Definition. It doesn't include the universal units with 6.2" display for now. Seen in Android-caraudio.com .

I believe the microsd slots themselves are part of the front panel, so if you're getting a new one, it's likely to fix that issue if it's hardware related.

Same model?

Hi everyone.

I have just purchased a similar unit ready to fit to my new car that I pick up on wednesday.

I cannot post a link but its being sold on ebay (uk) for vauxhall astra's (Duel Core 1.6Ghz cpu, 7inch screen android 4.2.2.)

Is this the same as the units that you are all using by any chance or yet another varient?

Thanks in advance for any help

Regards

Mark

It's hard to tell without seeing a picture of the back of the unit or looking in the "About device/tablet" screen on the device.

This one http://pages.ebay.com/link/?nav=item.view&id=281376782040&alt=web looks like a huifei/kgl from the picture of the back

The problems, were that I still had to buy an aftermarked mount to secure it to the dash, they the volume would change at random all the time, and switch modes also, so it was unusable. I updated it, and that fixed those issues, but I still cannot get it to get radio signal, and hooked up an amp to power my speakers, but there is a constant annoying hiss and crackle. And worse, there is no subwoofer control, and the built in amp is crap, only controls balance, fade, and treble/mid/bass. I'm really lost on what to do as it makes my car sound like crap.
[MTCB Android Head Units Q&A] sprfly:
I think they will only be sending the plastic pieces and not any of the circuitry. They are sending it because the buttons shown in the listing did not match what I received. My plan was to swap the buttons and then just reassign their function to get, in the end, what I had originally intended. However, now with this latest issue with the SD slot I am thinking I need to send it back. On the other had I won't get one this cheap again :confused:
[MTCB Android Head Units Q&A] that_dood:
Did you figure this out?? I'm having the same issue. Can't really tell I have a sub even there
[MTCB Android Head Units Q&A] mrd0c:
I guess you are talking about the rear speakers problem.

I think I know what is happening, but note that I may be wrong since I couldn't try this solution yet, and I have no knowledge in audio.

As far as I know this problem is caused because the rear speakers and sub in our car are amplified, the front ones are not.

The signal needed for front speakers (high impedance) is different from the signal needed for the amplified rear speakers (low impedance)

Our original Audi radio output each signal in the correct impedance, but the HuiFei unit output high impedance signal for every speaker.

So what is needed is a 'High / Low impedance adaptor' for the amplifier.

If I'm not wrong, mikejclark is using an adaptor that solved the problem, and I believe is that one.

@ lock screen wanting person

you need to find the keystr file (or make one if need be) and change it to on. I have been playing with multiuser and it somewhat works but needs a lockscreen. or maybe try to run this

sqlite3 /data/system/locksettings.db "UPDATE locksettings SET value = '0' WHERE name = 'lockscreen.disabled'"

after playing with it yes the sqlite is installed on the unit and it will enable the lock.

You can also get usb debugging by playing with some settings in these files too

I will play with it to see how stable multi profiles is. Seems to work though. Start car pick a person. Wish tasker would update to change profiles by bluetooth connection. That would make more sense, and just be excellent. Anyone know the developer?

Poweramp has a setting to pause or lower volume when other sounds are played (eg nav, text msg, etc). I think it's under the Audio settings maybe.

The closest that I've seen & used is the Pioneer AppRadio 2/3, and the Parrot Asteroid. Neither of which I was overly satisfied with, which is why I went with these headunits. They are far from perfect, as there really is no such unit that pleases everyone with zero problems. But they're about as close as you can get to a customizable Android experience in a car, while also having an integrated am/fm tuner.
[MTCB Android Head Units Q&A] robertusIT:
so about your experience, between parrot asteroid smart and pionner appradio, you prefer.. ?

because parrot have a price of 500€ and works also without my phone, but pioneer SPH-DA110 is 280€ and without phone you can do nothing. ( i don't know which product is appradio 2/3, i found only SPH-DA110 )

How to setup car clock

Hello,

I have a KGL-7091 unit and I don't know how to setup my car clock using this unit.

Before I replace the original radio by this android unit I used the radio button to setup the car clock.

Some one know how to do this?

[MTCB Android Head Units Q&A] typos1:
Basically, you have 2 choices, these RK3066 units, or an AN21-U, forget the Parrot and Pioneer, they are overpriced and not very good.

Sharing Digital have recently released an Android headunit that is entirely button free, (I think its RK3066 based like these units), thats your only other option if you want no physical buttons.

[MTCB Android Head Units Q&A] typos1:
Nice idea about upgradeable units, but I m not sure it would happen as it would all be down to the manufacturers and they would rather sell you a complete new unit.

The Chinese can be a real pain to deal with, so I know how you feel ! The language barrier doenst help, Chinglish can be real hard to understand !

As I was saying to ptclabs a few days ago, this field is an area where the Chinese are actually ahead of the established western and Japanese/Korean brands. Google and Apple are moving fast with their car centric developments - I dont think you can afford "play the waiting game", things are moving too quickly for that.

I actually think, now we all have smartphones, that the best thing would be something like these units but without the Android bit and with an MCU that can handle FULL Mirrorlink capability so you you just basically control your phone/tablet from the headunit - the Android bit would be in your pocket (or the Apple/Windowsphone bit, it would have to be compatible with at least the main OSs). Why have 2 androids when 1 will do ? Plus all your personal stuff wont be accessible by anyone else if your car is nicked (esp your home address on the sat nav) and if all cars had this set up we all could simply listen to our music/use our navs/use our phone/view our photos etc in whatever car we happen to be driving.
[MTCB Android Head Units Q&A] typos1:
No, just cos your SWC works does not mean you have full 2 way CAN Bus working.

What MCU version are you on ? The reason I ask is because someone recently posted that the latest update enabled 2 way CAN Bus and that they coudl see the info from the headunit on their car dsahboard and that they could work their HVAC from the headunit. I think it was a HuiFei unit they had. What MCU version are you on ? I m sure they had a VW, maybe it does not work on Renaults yet ?

The idea to make the units upgradable is less of a marketing ploy as it has to do with manufacturing. The more you can standardized and use tooling and circuit boards over and over the better of you are..

I spent 10+ years in the car audio industry and now 15+ in tech there are a few things I can say about both.

1. In Car Audio, people buy one replacement radio per car, unless the replacement breaks. But they are brand loyal. Once they have a brand they trust, it takes something major to make them jump ship.

2. In tech, laptops have offered upgradeable hardware for years. Anyone care to guess the percentage of people that actually upgrade? Less then 5%. Laptop gets to slow, they buy a new one.

I just see a gold mine here, have the backing to start digging, but can't get anyone to tell me where the land is. Its frustrating. :)
[MTCB Android Head Units Q&A] agentdr8:
Sorry I wasn't clear. It's the AppRadio 2 (SPH-DA100) and AppRadio 3 (SPH-DA110). The AR2 has been discontinued by Pioneer, but some prefer it over the AR3, due to 3rd-party app support (ARliberator doesn't work with the AR3 last I checked; but ARUnchained does).

I didn't like having to connect my phone via MHL to the AR2; it was cumbersome and made the phone really hot when using nav (Maps, Sygic, etc). I always was irritated having to hit the disclaimer OK every time the unit booted up. It would have been much better if the unit didn't lose power when cranking the car, like when you stop to get gas, and then have to restart it. It disconnects the phone, which then makes it take that much longer to get music/nav going again.

The Asteroid would have been better if it was running a modern version of Android, and had built-in Play Store support. It's like a more polished version of these HuiFei headunits, but with its own limitations. Maybe if Parrot tries again with a newer, more open platform, at a lower cost, they'd have a winner on their hands.

I think with Google embracing the platform for automotive applications in Android L, there will be a lot of new choices in the coming months. Hopefully the major players (Pioneer, Alpine, Kenwood, Sony, etc) will take notice and produce something worthwhile. Until then, the KGL suits my needs just fine, even if the overall aesthetics leave much to be desired.

Opinions?

So I am coming up against my paypal return window. I was originally going to send it back because of the buttons not being what was in the ebay listing and the missing mounting brackets. However, I then got the seller agree to a 90$ refund and they said they would send me the buttons I wanted(how true this second part is I'm not sure). Now I have come to realize that my GPS card slot is probably bad, it won't recognize or mount any card I put in, it acknowledges when the card gets removed though which is strange. At this point I have paid 225$ for the unit as I also used a 35$ ebay coupon. I have a paypal dispute that has been ruled in my favor for a full refund, I only have to provide tracking information by the 5th. If I return it I'm back at square one and have to find another unit to buy and I know I'm not going to get one for as low as I have this one for currently. Would you guys send it back or keep it and just deal with the GPS card slot not working. The media slot works and I was able to have to maps working from that slot but then that slot is occupied by the maps card. Would you send it back?
[MTCB Android Head Units Q&A] agentdr8:
If you get a large enough microsd, you can use it for both maps and music files. I guess it depends on whether or not you want 2 working slots or just 1.

Since yesterday i am using the 2.02 update.img together with KGL4 from 1.99 version. I was unable to use the KGL that came with 2.02.

Still there is only very simple CANBUS support for my car. SWC is bugged with that software version. If you click VOL+/VOL- the unit ticks volume up/down 3 times.

At least i can see door status in the display, that feature didnt worked on earlier version 1.77.

Multi user

I have it working fairly well it seems stable.

I had to use scripts and shortcuts to change the user because of the lack of a stable lock screen. The lock screen only is displayed for the second user though. I can get the primary user to lock but it is somewhat unstable.

Now the last step is to get it to run the script when it connects to my wife's bluetooth and not mine. That is the last step. I think tasker can handle that.

Everything seems to work. have to restart twice to get the wifi working on second account when you first add the account. It restarts once automatically.

You know its on the second account when the lock pops up.

No more biggie and crap on my iloveradio. Much better. No more emails every 3 minutes either.

Spent the afternoon ripping my hair out about the lock. He has to have it disabled by program and not flag..Some prewritten apps will override it, but it is unstable as your telling it to lock and unlock at the same time. Why the hell would he do that? Maybe it was just easier than making the apps not sleep with the lock on. Makes no sense to me at all. Seems it is attached to the "preinstalled" profile with the chinese name.

You can even get to the lock options by using hidden menus. Even set a uinlock code if you wish...

Anyone have any good ideas on how to delete that profile? Like doing a factory reset without doing a factory reset. I think we would have to pull apart the rom and delete it from there as it seems to recopy a bunch of crap every time it restarts in to the system directory.Including this profile.

If you want a stable lock screen. run multi user and make a new profile. Set the unit to switch to the new profile on every start by script. Requires root.

'membering from my head it is

am switch-user userprofilenumber

you will also have to enable the screensaver in data/data/com.android.IFORGETDAMNIT.settings/database/settings.db if you want it to relock other than on start.

hidden menu is your friend also.

Apparently it only works on VWs/Audis, so it should work on yours. I do remember the first person to report 2 way CAN Bus working said he had the same problem (post 2628), I dont know if he sorted it, maybe pm him (or her) ?

Apparently 2 way CAN Bus is only working on VWs/Audi at the mo (see below). you could try installing the latest MTCcanbus apk, but I m not sure if it will work. I dont know what would happen if you tried other CAN Bus options in the menu, I would assume that it just would not work properly, i dont think you will break anything, but I could be wrong. Maybe get in contact with KGL and ask them to develop 2 way for Renault, tell them you cant set your clock etc.

It is a good idea. Do you also mean having the ability to update the CPU as well as the memory ? Effectively change bits on the motherboard like a laptop or pc ? I dont wish to be negative (because it IS a good idea) but because of the speed that tech moves at nowadays, would the motherboard necessarily be able to handle a more up to date CPU ? And it would obviously have to be compatible with a higher amount of RAM for it to work as well, so there will be a limit as to how much updating you could do before the motherboard would not be able to handle it. I think these RK3066 use 40nm tech, they are already quite out of date - Rockchip launched the RK3188 quad core last year using 28nm tech and this year the 3288 (faster, still 28nm). So you d have to get a motherboard specially made (without soldering, so the CPUs are removable).
