what mods did you make to the radio app? I wonder if theres a way to make it save station names...

So flash and backup at will now :)
[MTCB Android Head Units Q&A] derpderpy:
In the photo you posted for the KGL, at the top right I see MIC1 on the PCB. Did you snip those wires to resolve the microphone quality issue?

Does this just disconnect the mic completely from the bluetooth module, eliminating the unshielded path that causes the interference?

I saw the JY version on aliexpress for around $289. but since no one had heard of it, decided not to try it - and got the kld version.

its possible the JY does fix issues since its newer than the other units.

I think i will also go for the KD version...It will cost me 330$ (around 260€ , where are the old times with the good currency exchange :crying:)

Your unit came with 2.03 version? EMS shipping?
[MTCB Android Head Units Q&A] sadam34:
Hi Guys,

I believe I have the KLYDE version of the three radios.

I have a 2007 Seat Leon and I am suffering from battery drain with the radio in the car.

Drained my battery in about two days so there is a small drain on it to the point the car wont unlock without the key.

I removed the OBD as I thought that was causing the issue but it is not it.

I check the radio after 2 mins and it doesn't turn on after the car is powered down and it "powers off" with the ignition but it drains the car battery slowly.

Any ideas to the cause? I searched the thread before and couldn't find anything exactly similar to the issues I'm having.
[MTCB Android Head Units Q&A] makkan00:
Thanks. I remember that I bought one last year and it should be somewhere at my place. Will dig it.

Re: TV, you are lucky if you get the signals and they are there while driving.

No signals good enough in UK.

I installed Kufatec BMW kit in BMW and that works so good but as Typos said earlier, you need diversity antenna and tv module with two antenna. Kufatec kit had that.

My friend, give yourself a favour.

Dont buy this unit.

I had AN-21 unit and that had minor issues which I resolved one by one within a week.

With this unit, it has list of issues and despite of updating firmware, it does not work well. The only plus side is that it has good sound.

When you refer to E90, it has two underseats subs and it will require excellent front channel amp.

Go for N6 which is best unit for bmw so far (if you cannot go for oem navigation)

[MTCB Android Head Units Q&A] bom-desolation:
thanks for the suggestion

I don't think the dynavin N6 is android-based, and that's a problem since the stock iGo primo is not very good at route calculation. I would absolutely want to run TomTom for android on it, or at least Sygic
[MTCB Android Head Units Q&A] cadillackid:
there are a lot of good plug and play smart-radios on the market these days.. many of them are just that stuff it in the dash, turn it on and you basically have a less costly, often better version of what wouldve been your factory navigation option for your car.. things like the parrot asteriod(for the most part), Dynavin N6, Pioneer AVIC ,etc all fall into that category...

the radios mentioned in this mega-thread are in my opinion for those that wouldve (or have formerly) built a CarPuter.. Like dealing with a carputer there werre often hardware considerations, hacks, software changes, writing your own apps, etc.. anyoe who ever built a carputer knows the amount of hacking and tinkering that was needed to get completely setup and working right... (learning whats compatible and whats not, what apps run well and dont, firmware updates and mods, roms, etc)

the trouble is these radios are being sold as just stuff it in the dash and go by their manufacturers.. and alas you have those

that want plug and play buying them (through no fault of their own) and then having issues... its a marketing ploy and blunder on the part of the manufacturers to sell these units this way.. esp when they are so newly released...

[MTCB Android Head Units Q&A] Vietxtlife:
hi guys, anyone know how to install sygic or igo from sd card to the unit?
[MTCB Android Head Units Q&A] agentdr8:
The included File Manager app works fine. Just open the GPS card (or SD card) on the left, browse to the apk, tap once to highlight, again to execute.
[MTCB Android Head Units Q&A] bom-desolation:
Pioneer AVIC or Appradio is just ridiculously expensive, especially taking into account what they charge for a steering wheel control interface

We have a Dynavin, it was a big disappointment. Radio was awful, sound quality soso and it was WinCE based so navigation was not great.

If that N6 would run Android 4.x and let me put TomTom on it instead of iGo, and have proper radio reception this time, I would put the money down for it.

I have no issue with setting up a carputer, that's why I was interested in this unit, but it's still a big investment so I do want to make sure that key features work properly (bluetooth/handsfree, navigation, navigation not dropping out on an incoming call, etc...)

Putting time and effort into it is no problem, but I know there are plenty of E90 drivers out there so I want to make an informed purchase this time, not an 800EUR radio full of flaws like our first gen Dynavin was
[MTCB Android Head Units Q&A] typos1:
Navall has been selling these units and the previous 2.3 version for E46, E90 and Rover 75/MG ZTs for years with loads of satisfied customers.

They are based in the UK. It is possible they tweak the units a bit, I know the 2.3 versions at least had a customised interface.

[MTCB Android Head Units Q&A] makkan00:
Ok, I have two android units now to play with

I have AN-21

and HuiFei.

I have a fully working copy of igo and that works flawlessly in AN-21.

When I use that in HuiFei, it looses the GPS signals when I come out of igo and play with radio / music player

Some have suggested me to try tomtom / sygic but to me it appears to be HuiFei fault or MCU fault that it does not allow GPS signal retriever in the background?

Anybody else had this issue and any solution to that?

Why don't you get bmw original navigation (CIC) installed. They are reliable!
[MTCB Android Head Units Q&A] agentdr8:
So if you have a route planned in your nav app, and background it, it won't give you guidance info? I know when I've backgrounded Sygic or Waze, it continues to give me directional advice.

Each application that registers a location provider is responsible for maintaining it throughout the application lifecycle. Unless your headunit is killing off the app to free up some memory.
[MTCB Android Head Units Q&A] bom-desolation:
CIC costs about 2500-3500EUR to retrofit (3500 - 5000 USD), that's about 40% of what we paid for the car. Not going to happen I'm afraid :)
[MTCB Android Head Units Q&A] makkan00:
Yup, but when you background it, it looses the navigation signals. And iGO keep saying 'signal lost'.

No issue with AN-21.

On Huifei, when I open the application, it says registering IMEI. So it think that this unit is phone....

I guess I do not have much option than to try tomtom or sygic.

Again, when I installed sygic, it says downloading files. So could not make it to me :(

Great !

Does your RoadMaster have 4 audio RCA pre-outs, or just two ?

Cos its expensive and you cant put any apps on it !

Why dont you do some research about the Navall units, as I mentioned in my previous post ? Loads of BMW owners and Rover/MG owners swear by them.

There are 100s of Nav apps in the Playstore, why dont you try some more ?
[MTCB Android Head Units Q&A] makkan00:
I have CIC and NBT in my bimmer and I can tell you that its much more better than any of these chines units. Who need application when we have phones / tablets for them.

As far as we can connect our phone and get our tunes, they work flawless.

Coming back to nav application, I stick to developed nav applications than trying 100s of applications. I will have a look at sygic / tomtom when time allows.

Thanks for your help so far :)
[MTCB Android Head Units Q&A] typos1:
You cant drive along and use a tablet, are you serious !! ??

And if you are and you prefer the very overpriced OEM sat navs, then why have you bought a Chinese Android one ?? !!

I dont know what you mean about "developed" exactly - ALL apps are "developed".

There are lots of navigation apps available, all I m suggesting is that you try some others, why stick to just 2 when there are 100s available ?

Yeah, I m sure some will not be very good, but I m also sure some will be great, you wont know til you try them, most are free or have free trial versions.

New Custom Firmware

i downloaded this Firmware for my GS Unit and its works pretty well.

[MTCB Android Head Units Q&A] Skitals:
Possibly some good news. I found this new listing on Aliexpress that shows what looks like a HuiFei. RK3066, Mali-400 GPU, etc. But it is running Android 4.4.2! Looks like there are new application icons, a new radio app, new BT app, redesigned filemanager, etc. Since the hardware looks identical I assume this update should be available soon to all of us. Unit also has the new 1024x600 sreen, which is a new option HuiFei started offering on the 4.2 units as well.

Take a look here for the listing.

I also found these two (mazda and bmw) that say they have a 1.6GHz RK3188 CPU: The About screen is pictured for the VW unit above, and the kernel definitely says RK3066 and Android 4.4.2. I have a feeling RK3188 is a typo on these listings because RK3188 is Quad Core and these listings also state dual core. The clock speed also matches the RK3066, not RK3188.

Another one (Mazda) from a different seller.

And the BMW listing.
[MTCB Android Head Units Q&A] webdude12:
Looks very fimilar to this one: Audi A4 - 4.4 Unit

Except this seller is claiming RK3188 which is the quad core 1.8Ghz CPU.

I have asked for screen shots of the About screen to get the MCU and Build info. So guess we will see if I get a reply.
[MTCB Android Head Units Q&A] Skitals:
Yup, looks like the same thing. Except " RK3188 1.6GHz Cortex A9 Dual-core" doesn't exist. RK3188 isn't dual-core, and doesn't run at 1.6GHz. I'm betting these are all RK3066 like the first link I posted, which has the About screenshot to confirm. Which is good news for us since it means its identical hardware and everyone should be able to update to android 4.4.

[MTCB Android Head Units Q&A] typos1:
Interesting, just a minor point, but the frequency also matches the 3188 - thats 1.6 Ghz as well, albeit as you said quad core not dual core.

My Klyde has good radio reception in the rain, wonder why yours didnt ? Mind you the AM reception is not very good, but this is common for a lot of aftermarket and OEM radios nowadays. I think a booster would help, was it AM reception that you had a problem with ?

As I said above, the 3188 is 1.6Ghz not 1.8 (though it can be overclocked), its common for many Chinese sellers to overquote the clockspeed, I ve bought several Rock TV boxes and they were all over quoted by 0.2Ghz.

The only 1.8 Ghz chip Rockchip do is the RK3288, also quad core.

Thats ok, but I think youve missed my point - Navall units are HuiFei units !! (see podge3's post above your last one)

---------- Post added at 12:49 PM ---------- Previous post was at 12:29 PM ----------

Its the MCU and related complementary that is different, the Android side is the same (an RK3066 tablet board), thats why the Android updates are interchangeable, but the MCU updates arent.

The BT module powers the MIC input @ ~1.4V. All car mics are electret with internal impedance matching FET (including the parrot ones). The Android CODEC can also bias the MIC (it has a separate pin for that) but it was disabled in the build by not installing a jumper resistor from that pin to the MIC since they shorted the internal and external mics (very bad practice).

[MTCB Android Head Units Q&A] Skitals:
I'm pretty sure the radio reception is partly/mostly my car to blame. The VW dual fakra diversity antennas have a bad reputation with aftermarket stereos. I have tried FIVE different antenna adapters now, all with largely the same result. I have returned the Klyde and got a full refund due to the missing GPS atenna and remote control that was advertised as included. Back to the GS (running latest klyde software). Of note, I completely rewired the GS wiring harness and the audio popping issues I had are gone. The harness came wired with two different factory connectors so everything was split in a "Y". I removed the extra connector and rewired it all so nothing is split and it's much better.

I see now the RK3188 is also 1.6GHz. Looking at this listing, it lists the GPU as Mali-400MP4 @ 250MHz up to 400MHz. AFAIK, the Mali-400MP4 is correct for the RK3188, but the clock speed should be 533MHz up to 600MHz. The 250MHz clock speed matches the Mali-400 (Non-MP4) which goes with the RK3066. Based on that and the fact all the listings state "dual-core" I'm pretty certain these are all the same hardware... RK3066/Mali-400.

My GS LEDs come on when the running lights/headlights are on, and turn off when they are off. The dashboard dimmer knob doesn't affect the intensity of the headunit LEDs though.

I've noticed that the unit doesn't always power up when I turn on the key. If I click the power button, everything comes back up, though, so it's not *that* big of a deal. I'd say it powers up on its own about 20% of the time, and usually only if it hasn't been powered off more than an hour or so.

Thus I'm sorry that I don't have a guess for you what else to try but just claiming a replacement of the DTV box by your reseller.
