Which unit did you have? I read different reviews about 1gb ram units. Some say it's reasonably enough, while others say it's not enough at all even for light use. I'm confused
[MTCD Android Head Units General] CadillacMike:
I have the issue where it does not initially find a signal
[MTCD Android Head Units General] demo84:
It wasn't Joying unit but still 1GB ram. Awful

No issues here
[MTCD Android Head Units General] KamaL:
I see.

Do you have The JOYING 2gb version now? Did you notice a considerable improvement in performance?
[MTCD Android Head Units General] rhino6303:
Would someone mind checking if the 2 gb joying intel units are otg compatible? I couldn't find it in ther descriptions. Thanks.
[MTCD Android Head Units General] demo84:
Yes I do have .Huge difference, you can't even compare them

It's single din unit
[MTCD Android Head Units General] demo84:
What you looking to connect to the unit?
[MTCD Android Head Units General] KamaL:
Good to know. I'll look for a 2gb model then.

Regarding otg, one interesting thing is using the USB connection to connect to an Android smartphone both for charging and for USB tethering this is easier than wifi tethering, consumes less battery and charges all at once.

This would need a high voltage from the USB ports, which I'm not sure is possible
[MTCD Android Head Units General] ProfEngr:
Not high voltage, but relatively high *current* output. Most modern phones need at least 1.0Amp to reasonably charge with the screen off. A Note 4 (if the screen is on) will need more than that. Typical USB sockets will source a maximum of 0.5Amps. You might try OTG with a powered hub, but that's just me speculating. I've done this with a 1st Gen Kindle Fire for watching movies, but the USB Y cable would either allow the battery to charge the Kindle or allow the Kindle to read the USB sticks; not both unfortunately.
[MTCD Android Head Units General] dcman008:
Are there any custom ROMs for the 2gig units?
[MTCD Android Head Units General] KamaL:
Yes, I meant current, you're right.

A powered hub could be a possible solution, will look into that

My obd2 connector. I have a bluetooth connector as well but want to be sure I have a backup in case I can't get bluetooth to work correctly.
[MTCD Android Head Units General] WILD9:
Still a little confused about the Bluetooth on these new units. Are you now able to connect devices other than phone audio profiles such as tethering/OBD readers/keyboards/mice etc or is it still the same problem as the older units? How is the Bluetooth audio quality now for both calls and music, I know there were some issues on the older devices?
[MTCD Android Head Units General] m3co:
I pull the trigger in a unit, should get it this week, will happely help you guys to take any doubt in it if i can, hope every thing works, looks a great unit, too bad the camera cames in seperate and takes a little long to get here (europe) but in mean time i can test everything else.
[MTCD Android Head Units General] doitright:
Hey, if you're really a "ProfEngr", you'll know that V(oltage) = I(current)*R(esistance).

In other words, in order to ACHIEVE the higher current, you actually need to bump up the voltage.

The "fast charge" chargers these days, will actually have multiple different voltages listed on their side, corresponding the the different charging rates that they support. The charger that came with Nexus 6, for instance, output 5v, 9v, and 12v.
[MTCD Android Head Units General] WILD9:
You've misinterpreted the implications of V=I * R somewhat. You can increase the Power (Watts) by increasing either the voltage or the current. Heat becomes an issue with high currents at low voltages so Quick charge etc use higher voltages to mitigate this but there is no reason you cant have a higher current at the same voltage other than this. Standard USB ports/chargers run at 5V from anywhere between 500ma and 2.4A depending on design.

If you imagine it like a water pipe I can let more water flow by increasing the pressure or making the pipe bigger.
[MTCD Android Head Units General] doitright:
The pipe (R) is constant.
[MTCD Android Head Units General] CadillacMike:
Bluetooth phone calls on my MTCD were isolated to one speaker, i do not have that issue on my Intel, the audio sounds normal

Bluetooth audio on my old MTCD was fine, and it is just as good on my new Intel

on the old MTCD, I was able get a OBD2 to work fine, but i could not get it to connect to my Intel, phone connects fine, I have not tried any other devices
[MTCD Android Head Units General] WILD9:
The pipe analogy is related to the formula Watts = Amps * Volts (Water flow is a function of volume and pressure) and doesn't really have an analogy for Resistance

Do you understand that standard (non Quickcharge) USB Ports always function at 5V but can provide higher or lower current depending on the design? An older computers USB port is generally able to provide ~ 500ma whereas a modern phone charger will provide 2.4A at the same 5V voltage.

I'm going to let someone else explain this better than me I think.
[MTCD Android Head Units General] doitright:
Do you understand that this (1) isn't a hard limit, and (2) exceeding 500 mA could burn the circuits in certain devices (both the supply and the drain)? As such, correctly built USB circuits will cut off if the current exceeds a certain threshold, not that all actually do.

And that the voltage you are looking at when measuring the power isn't actually 5v, but rather the voltage DIFFERENCE between the power source and peripheral? So say you are charging a typical phone battery, it is at 3V, your voltage difference is 5V-3V=2V. That is the number you are working with in order to determine how fast you can charge. As the battery voltage goes UP, the difference goes DOWN, and the rate of charge goes down with it.

Now throw a voltage inverter into the peripheral, and you could bump up that voltage DIFFERENCE, thus increasing the rate of charging. Further, a USB powered device is different than using USB to charge, since with a powered device, you are dealing with the full 5V rather than the difference.
[MTCD Android Head Units General] WILD9:
This is generally correct but the discussion started with someone hoping that the USB port was able to supply enough power to charge the phone whilst it is in use. Assuming the headunit doesn't support quickcharge or USB PD Spec (which would both be unusual on a data port) the USB ports on this device will work at 5V so the only relevant factor is how much current it can supply to the device and how much of that current the device is able to use.

Taken from the USB Specification Wikipedia page for illustration:

USB power standards

Specification	Current	Voltage	Power
Low-power device	100 mA	5 V	0.50 W
Low-power SuperSpeed (USB 3.0) device	150 mA	5 V	0.75 W
High-power device	500 mA[a]	5 V	2.5 W
High-power SuperSpeed (USB 3.0) device	900 mA[b]	5 V	4.5 W
Battery Charging (BC) 1.2	5 A	5 V	25 W
Type-C[c]	1.5 A	5 V	7.5 W
3 A	5 V	15 W

[MTCD Android Head Units General] wanb1i:
I agree with doitright, I had the same issue. Personally, I believe that these units are not "in stock", but "in production" and are actually "made to order". Which is what causes their pre shipping delays.

Use the head unit to log GPS, its a valid speed measure that the court will accept. As long as it reads lower than the COP, it will call into question the accuracy of the COP's device -- essentially, they can't hold you to anything higher than the LOWEST documented speed.

Got it and I love it but I need some help!

Hi all..

I got my 2gb 5.1 from joying on aliexpress

since i am new to the forum i cannot post links but if you go to aliexpress and search for the title of the product i bought:

2G+32G New Android 5.1 Quad Core Universal Car Audio Stereo GPS Navigation Double 2 Din 1024*600 HD Car Radio Multimedia Player

i got it during their 1111 sale for $340 canadian dollars. it only took 2 weeks by ems. i was very specific about them using ems because you never get charged a customs/duty charge if shipped ems ;)

So i got it installed professionally into my 2006 lexus rx 330 and it works great but i have one main issue. well 2 issues. radio signal is not great. but my main issue is this. there are 2 video outs on the back of the headunit but they don't work and joying said yeah sorry, they don't work so wtf? why would they have them on the back of the unit? so the reason i need a video out is because my vehicle has a factory dvd player for the kids but in the trunk there is an analog in (rca red white yellow) presumably so the kids can play a video game etc. on the dvd player's screen. Well i want to use kodi from the head unit to play movies on the back screen so i had the installer run the yellow rca from the video out to the trunk video in which, should have worked but it does not because as per joying "headrest monitors not supported".,

So, question is.. can i use one of the usbs (there are 2) to mirror what is happening on the headunit onto the back screen. so usb to rca video cable? or will it need to decode it? does video even come out of the usb or do i need an app or something|? any help would be greatly appreciated -especially by my kids zoe and apollo!

oh yea and the odb elm wont connect to bluetooth. joying support said to update the firmware. this is the link to the latest firmware (if anyone wants it) as per joying:

[MTCD Android Head Units General] doitright:
The actual model number for the unit would be helpful...

Is it a standard DDIN shape with 7x4 inch face?

Does it have a KNOB up at the top/left? UL135N2

Does it have a KNOB at the mid/left? UL124N2

Does it have an all glass panel with NO knob? UL128N2

Is it non-standard display, like 8" or 10"?

Ok, so yeah. You've just discovered that ANDROID cannot output to the yellow-wire-outputs. However, as far as I understand, that doesn't mean that they are completely non-functional! From what I can tell, it is a kind of pass through video cable. One of the yellow wire connectors is a video INPUT. Now thing is... I'm not sure if that is just an idiotic video cable splitter, or if it is capable of ALSO playing the video on the head unit itself.

Point is, of course, that you're going to need a separate video SOURCE in order to make those connectors output ANYTHING. Perhaps a Raspberry Pi 3? Next up, you need to think about controlling that rpi3, you might set it up to act as a UPNP/DLNA player. Now this is where it gets fun -- XBMC/KODI (and many other programs) can be configured as a UPNP renderer. In other words, it becomes a screen, and you run a client (control point) and server on the head unit. This would allow the head unit to feed a video stream out to the rpi3, which plays it back on the screens.

Sure the court will uphold the accuracy of a chinese headunit. :) Anyone having faith in the above advice is potentially in for a big surprise.

---------- Post added at 08:01 AM ---------- Previous post was at 07:57 AM ----------

Yes it appears that most manufacturers build in speedo error so the vehicle will read slightly higher. Your thoughts as to why that may be.
[MTCD Android Head Units General] doitright:
I don't think you understand how the law works. It doesn't MATTER if it is accurate. All that matters is what you can reasonably be expected to understand. If you are going 200 mph in a 55 zone and your chinese radio is reading 55, then that is not reasonable for you to believe. If you get tagged at 60 in a 55 and your radio reads 55, then you get off. If you get tagged at 70 in a 55 and your radio reads 65, then you get hit with 10 over instead of 15.

I.e., it isn't SO FAR OUT that you have any reason to doubt its accuracy.

WORST case scenario, is the court tells you not to go by the chinese radio in the future.

---------- Post added at 02:42 AM ---------- Previous post was at 02:20 AM ----------

Off topic... but DOT rules allow for mechanical speedos some leeway. If I remember correct it was something like +-5% at 65MPH. Things like changing rims and tires will change how a mec speedo will read. OEM are hard pressed to make 10 speedo part numbers when one car model has 10 tire and rim combos.
[MTCD Android Head Units General] WILD9:
Has anyone moved to one of these from a more mainstream aftermarket headunit like a kenwood/pioneer/alpine? Whats the sound quality like?

Also does "OK Google" from any screen work with these?
[MTCD Android Head Units General] doitright:
Good thing that your opinion doesn't have any bearing on how the law works.

And this isn't anecdotal. This is HOW THE LAW WORKS.

---------- Post added at 02:40 PM ---------- Previous post was at 02:32 PM ----------

They don't actually make separate part numbers.

While any car model may have 10 tire/rim combos available, the thing you need to be aware of is that typically ALL of these combinations will have the same circumference (within a certain small variance), which means that the same speedo will read the same with all the different combinations.

The vehicles available with tires of different circumference are typically where the manufacturer offers a 4x4 version and a 4x2 version -- things like mid sized pickups and suvs. In these vehicles, they typically have a "large" size for the 4x4, and a "small" size for the 4x2.

On top of that, unlike how cars were way back in the 1970's, speedometers are no longer mechanical devices with cables and springs. There is a sensor that reads the rate that the output shaft of the transmission turns, and that sensor feeds the car's computer, which calculates the vehicle speed based on the tire circumference and differential gear ratio. That speed is then fed into the dashboard display, which typically has a needle that is controlled by an electromagnet to make it LOOK like an old fashioned mechanical gauge. In other words, the tire size and gearing compensation is now all done in SOFTWARE.

My AM radio station sounds like poop, but that's reception related since I can't figure out how to set the radio to tune to north american frequency standards, which means I'm locked in to a frequency that is 2 kHz away from the target.

I honestly am not an audio head. Took the factory radio out right away because it didn't have nav or BT, replaced it with a kenwood. kenwood was a complete and utter piece of poop that took a year to boot up, small screen, and how the hell many stupid labels do they actually need to paint onto the front of the thing??!?!?!

I'm running RemixOS 2.0 on my Pine64 2GB but I can't change the output resolution of the Pine64 to 1366x768.

1366x718 is the native resolution of the Nexdock.

Nexdock works together with Pine64, but all text is hard to read because of the wrong display setting.

Any solution or Remix OS update to fix this issue?
[Supported Devices] nightranger73:
I'm on the same boat as you.

Running debian the display is using the right resolution but obviously there's no GPU acceleration and no bluetooth working.

Bluetooth will get a fix in the future probably but I have little hope for GPU on debian. That means no usable Kodi-

At this stage of development Android (and RemixOS) seems to be the better solution for the Pine64.

On PC you can change the vesa mode at boot but I don't know how to do it on Pine.

I've seen many posts about this around the internet and from what I've read it does seem to be faulty hardware.
