[MTCD  Android Head Units Q&A] BlueVan:
The extra 1GB adds more than perhaps you'd think because the Android system is consuming a lot. Say the system's consuming 0.8GB like my phone right now. If I had a 1GB phone that would leave 200MB for apps/app data. Add 1GB and you have 1.2GB for apps/app data, 6 times the space, Android is not having to spend so much time shuffling stuff from RAM to storage and back.
[MTCD  Android Head Units Q&A] Hilari0:
The Intel Sofia CPUs are quite strong CPUs, benchmarks aren't telling the whole story, as you can't really benchmark two completely different architecture and get any sensible results out of it. Antutu is optimized to benchmark ARM architectures, not x86 architectures, which will give a huge hit on the score for the Intel CPUs. And it's not impossible that the Sofia chips will get upgrades, as Rockchip had a big hand in making them and are still supporting and making them despite Intel pulling out of the Atom architecture.
[MTCD  Android Head Units Q&A] ikerg:
I am not saying that Intel sofia never will be upgraded....just the px5 is not suitable for Intel upgrading

[MTCD  Android Head Units Q&A] Techrev:
Yeah, well, there's no mystery with the PX5. It's strong, and it's the same platform I'm used to. If someone decides to do a side by side with the Sofia and the PX5 I'd like to see it, but there's no point in speculating. Most benchmarks do pretty well going across different architectures, tbh. Until there's more to go on than that, I don't see a reason to take them at anything but face value. There are way too many shills in here pushing their stuff, it's actually, pretty annoying. Post evidence to support your claims, but people spending half a thread trying to convince people of something they have no evidence to back up is pretty annoying. IMHO.
[MTCD  Android Head Units Q&A] Hilari0:
Well, you don't have to go further than some benchmarks between nvidia and AMD to find that benchmarks was more optimized for one over the other, it's a well known fact. ARM and x86 are completely different architectures, and seeing that pretty much everything that runs Android runs on ARM, it doesn't take a lot of rocket science to figure out that Antutu has been optimized and coded to run on ARM architecture. The measurement if A device is faster than B device is more than a benchmark, unless they run on the same architecture, which is why it's easier to benchmark different Android phones and even iPhones against each other, as they all use ARM. Some real world tests would be better.
[MTCD  Android Head Units Q&A] BlueVan:
I agree with TechRev. Plenty of tedious benchmark discussion threads all over the Internet. Let's keep this on topic. Sofia and PX5 2GB/32GBs are both strong.

If I had to buy a new HU now I'd go for one of the 2GB/32GB Sofias because there are a lot of models.

But I don't, so I'm waiting till we're a month or so into Chinese New Year and we see what PX5 units appear.

Ideally for me Joying will do a VW Jetta PX5 2GB/32GB with physical volume control/power switch but we'll have to see if that happens.
[MTCD  Android Head Units Q&A] dude-nl:
Trust me, it is the difference. I upgraded from 1 GB to 2GB on my rk3188 and no lag, hickups or what so ever...

With 1 GB there is only about 100-200mb RAM left what is not enough to run Android smooth.
[MTCD  Android Head Units Q&A] Nomader0:
is there anyplace we can get the RAM chips? i believe you got it along the group buy, correct?
[MTCD  Android Head Units Q&A] dude-nl:
Yes, I bought them in the groupbuy...

You need to be familiar with SMD soldering. It's not basic soldering.

I let my Mobile technician replace the RAM for me.
[MTCD  Android Head Units Q&A] Nomader0:
yes i know.. it is BGA chip.. but do you know any other way to get the chips, since the group buy is over and the second group buy is not alive
[MTCD  Android Head Units Q&A] dude-nl:
It's not alive because people don't read.

The 2nd groupbuy is already finished. Got mine from there.

You can contact the starter of the 2nd buy. He can provide you with the information where to buy. Maybe you can buy yourself then or start a new groupbuy.
[MTCD  Android Head Units Q&A] Nomader0:
i'd rather wait a bit to see if the PX5 boards are going to be sold as an upgrade.. that would be an easier swap, if not i would see about upgrading the RAM
[MTCD  Android Head Units Q&A] Techrev:
I'm feeling similar, though I don't have an MTCD unit, so I won't be able to upgrade anyway. The PX5 just seems like less hassle to me, and there's a cpu speed increase. Right now I have my RK3188 limping along somewhat by killing as many apps as I can that I don't use. It's a pain, but not so bad I can't live with it for a few months.
[MTCD  Android Head Units Q&A] Nomader0:
just disable google services.. you will be surprised with the speed increase..

[MTCD  Android Head Units Q&A] Techrev:
Except I use Google Maps a lot, unfortunately. Since I use PowerAmp for music I was able to kill the Radio app (which I never use) and a few other things. It helped a lot, but it's still swapping out more than I'd like. I was, more or less, fine before I upgraded the ROM to 6.1, I'm just too lazy to roll it back to 4.4.

**I could try switching to Waze or something, and see if it helps to disable google services, though.

**Edit: Thanks, this worked very well for me for the time being.
[MTCD  Android Head Units Q&A] _javi_:
I think it will be an instant success in sales if you provide the PX5 board as an upgrade for us PX3 users.

If you dont make it, maybe others will do.

Hello!

I have the GYR Audo (seller) / HotAudio (manufactured) Mitsubishi Lancer 10.2" Android 5.1.1 MTCD Quad-core RK3188 Cortex-A9, 1GB RAM headunit. I am extremely interested in upgrading the core board to the PX5. It sounds like a much needed upgrade, the headunit can get really slow at times, and the radio chip isn't quite as good as the stock radio: doesn't get as good signal strength.

I think [MENTION=6942549]hotaudio[/MENTION] stands to make great profits by allowing people to purchase the PX5 board alone for upgrades.

If the PX5 upgrade isn't compatible with my unit, how do I upgrade the RAM?

Does anyone know if the internal bluetooth adapter on these new octa-core units are bound (only visible) to the MCU? The problem with other MTCD units is that Android is not able to communicate with the Bluetooth adapter directly which prevents you from pairing non standard devices like a mouse, keyboard or radar detector module.

[MTCD  Android Head Units Q&A] dontpannic:
OK, So I currently have a KGL MTCB RK3188 1024x600 unit - if it were possible to get hold of a new board, would the PX5 board be a straight swap into this unit and work?
[MTCD  Android Head Units Q&A] marchnz:
Yes, appears to be a straight swap for MTCD RK3188 SOM.

We have mulitple posts for this same request - to purchase the SOM. Unfortunately reseller apparently wont supply as "spare part" and hopeful this changes as other resellers have offered in the past (e.g. Joying 3088 - 3188.)

Suggest that a supplier will eventually be found or HA provide (post initial sales of complete unit) as spare part.
[MTCD  Android Head Units Q&A] ikerg:
[MENTION=6942549]hotaudio[/MENTION] is not a reseller...is the manufacturer. I think they have done their business case and perhaps selling the board affects the core business of selling full headunits.

[MTCD  Android Head Units Q&A] marchnz:
Appears most likely. Who would want to purchase a unit that parts are not available for? I wont be. In contrast - Joying have been happy to supply parts on enquiry in my experience and even offer upgrades.

You could argue aftersales service, but if parts are not available, is too much of a risk.
[MTCD  Android Head Units Q&A] ikerg:
Parts are available....and board is going to be sold as a spare part for px5 new headunits

Are you affiliated or an authorised reseller of these HA units?

Who is the contact for spare parts and how has this been validated? I dont see any information on the reseller website. Note that the advice I have received is that the SOM is not available.
[MTCD  Android Head Units Q&A] dontpannic:
Thanks. What about MTCB?
[MTCD  Android Head Units Q&A] marchnz:
MTCD only as MTCB uses a different header connector similar to RAM modules. MTCD uses a cheap header/socket.
[MTCD  Android Head Units Q&A] typos1:
All but one of the MTCB manufacturers have stopped making MTCB units and now make MTCD units instead.

The exception is Klyde, who have simply upgraded the MTCB MCU software and called it "MTCC".

Most, but not all, KLD MTCB MCUs can be upgraded to MTCC MCUs as the hardware is the same.

Back in November, Klyde started selling their own PX5 based unit. I have not seen anything about these anywhere other than Kyde's website as yet, but potentially, if theyve used MTCC boards/MCUs and the same RAM type SoM connector, anyone with an MTCB or MTCC RK3066 or RK3188 unit could upgrade to a PX5 SoM, including non KLD units.

But until someone gets hold of a Klyde PX5 unit, we just dont know.

For obvious reasons you cant upgrade MTCB/C units with MTCD boards or SoMs.

[MENTION=6942549]hotaudio[/MENTION], is there any particular reason why you didnt post this in the MTCD forum where it belongs ? :)
[MTCD  Android Head Units Q&A] Techrev:
This is interesting. I apologize, since I didn't know these details. I will look for more information on the Klyde units.

[MTCD  Android Head Units Q&A] 93starletgt:
Hi there. I need some help, please!

I have this exact same head unit that I bought from Dasaita on AliExpress.

Today I attempted to install it in my 2013 Kia Rio. I used an ISO to Kia harness (for my specific model). After plugging everything I noticed that when turning the ACC off in the ignition key, the radio turned off instantly (like when unplugging a TV from the wall). When turning the ACC on with they key a couple seconds later, the radio did the whole boot cycle again. Also noticed I lost my radio stations and presets as well. That wasn't normal, so I switched the constant (yellow) and memory (red) cables in the iso harness and this fixed the problem, although creating a new one. Now, when turning the ACC off I finally see the proper "Powering Off" message (good so far) but only the screen powers off, and the whole unit remains active. I tried searching for the "Dormancy settings" using the 126 password, but the setting just doesn't exist. So decided to remove the key and wait to see if it would eventually turn off... and an hour and a half later, I inserted the key on and moved it to the ACC position, the screen turned on automatically but still in the PlayStore, where I left it.

This will of course drain my battery. If I tried to turn it off manually by long pressing in the knob, it will display the powering off message, but again it won't turn off. I think the wiring it's connected the proper way and I shouldn't go back to the way it was connected before I switched the cables. I find it weird that the ACC delay/Dormancy settings aren't the factory settings or anywhere else. Is it a software issue maybe? Any suggestions?

I appreciate your help! :)

I just installed the latest firmware and it still goes automatically into some kind of sleep mode when I remove the key from the ignition. I came back two hours later, inserted the key to ACC and the screen came on instantly showing the PlayStore (right where I left it previously before removing the key). I have also tried every option in the 126 password protected setting and tried long pressing the power button for 10 seconds. It Always goes into sleep mode, it never shuts down. This of course drains the battery of the car.

I concur with this - I have a PX5 unit in my 2016 Corolla - doesn't appear to have any sort of adverse affect on vehicle startup, albeit admittedly, I haven't found reason to measure any sort of power usage from the unit with the vehicle turned off.
[MTCD  Android Head Units Q&A] aeonfluxcapacitor:
Hey fellow Corolla 2016 owner, I just installed a PX5 unit in mine today and it took me a while to realize I had to set the canbus in the factory settings (password 126) to get my steering wheel controls working. What can bus came with yours? Mine says Toyota Prado 2014. And what did you set yours to in the canbus settings? A couple different options seem to work while the one marked Toyota Pardo 2014 (yes Pardo) did not.

I was able to get my SWC working using one that said Camry on it but the app for mapping/learning them does not seem to have any effect. A couple buttons don't do anything like "display" and I was hoping to map it to something useful.

Also where did you mount the GPS? I'm so fresh off the install that the unit is still hanging outside of the dash. Any other pointers? :)

All in all, having spent $$$ on this gamble (6.0.1, 2GB, 10"), I'm really digging it. Now its time to consider data plan options.
[MTCD  Android Head Units Q&A] droc.noles:
Here's the canbus setting I've used:

My canbus was the same as yours 2014 Toyota Prado - had to check with the seller as to whether or not this was correct until I figured out that the above canbus setting works for most of the steering wheel controls. I hadn't had a reason to check mapping until your mention that the display button isn't mapped (I don't use the steering wheel controls all that often, I admit) - not sure if that button can be mapped with any of the canbus presets in factory settings.

As to mounting of GPS / mic - I have not yet done anything with that until I know the unit is going to pan out. So far, I have just left these two in my glove box. GPS seems to function just fine there from my limited interaction with Google Maps to date. The mic, however, for obvious reasons, doesn't function all that well being stashed away like that.

A few things that I'm trying to get sorted, that I don't have an answer for yet:

Bluetooth randomly forgetting all connections at times

Poor WiFi speeds

Intermittent popping / skipping in audio every couple of minutes for a few seconds when using any music player short of the Radio app

USB Audio testing with Audioquest Dragonfly has proven to be unusable so far - popping / noise completely washes over what appears to be perfect audio playback in the background - this is with native playback in Google Play Music. Tinkering with various settings in USB Audio Player limits this popping / noise to just every couple of seconds, but still unusable at this point. I would like to get this working in an effort to bypass the internal DAC for an expanded stereo setup eventually (external amp, speakers, sub, etc)

So far though, all issues accounted for, I still like the unit. Very nice having such a large display in dash. I've got OBD working as well, which is nice to use with Torque on this display.

[MTCD  Android Head Units Q&A] droc.noles:
Indeed - was pretty relieved to see that the temp readout on the stereo matched the vehicle's readout.

I'm contemplating trying to disconnect the external mic without having to take down the dash again if I can. I had assumed that the internal mic was rubbish during install - wish I would have at least tried the internal first.

I am indeed in a US Corolla - I had to dremel a few pieces off of the top of the kit, and it gave me a little trouble getting the plastic clips tapped into place when installing - at least it's in and done.

WiFi continues to be dodgy for me. Still looking into a better solution for this. Right now I'm allowing a HooToo Tripmate Nano to negotiate connections, whilst connecting the stereo's WiFi to that. Not elegant, but it's working okay right now. I had looked into possibly USB tethering as well, but this stereo doesn't even seem to have the option to do this.

Bluetooth and audio glitching still is plaguing my unit. I do not have the extra audio output harnesses connected, so I know that's not an issue. I'm wondering if the audio glitching has something to do with an app that is pegging the CPU at times or something....still searching for answers on this front.

As to Bluetooth, this is just flat out not working well. Most of the time the connection to my Pixel just fails to even register after awhile, so calls just come through on my phone direct instead. That doesn't even account for how often I crank up the vehicle to find out that all Bluetooth connections have been forgotten, which happens every few days.

I'm still liking this unit as well, even with the current issues. Hopefully we can get these bugs ironed out.
[MTCD  Android Head Units Q&A] LogicGate:
First, very glad this thread was started. It's interesting to see how many of the issues I have are reported such as the Bluetooth not working and loosing all paired devices. Also the echo issue is very much a big complain for everyone that calls me too. The launcher is definitely not by choice, but there are plenty of launchers to choose from, such as my favorite Car Dashboard.

So here is my list:

* Bluetooth Issues and paired devices gone

* Call Echo Issues

* WiFi has terrible receptions (will fix with a new antenna)

Really would love:

* Ability to control the steering wheel button functions such as adding Pandora or Spotify as a "Mode" option

* Code for getting ROOT! What is the Factory Settings password to get root!? *#hct#root# doesn't work. :(

* Share internet with the radio without starting a hotspot on my phone (Note 4)
