GALA is working!!!!

I updated my previous post with it.

Also it will be available on Google Play for 3€ soon. There is absolutely no difference.

Why 3€? Everyone can get it for free here. If you want to support me buy on google play which will let you receive automatic updates.

I promise to always publish it for free here. when I update. So no need to buy if you don't want to!

Try Factory Settings (Pw is 126) and there you can enable it - BUT it will not work I think... At least for me it didnt... no idea what was wrong...

Wow, this is good stuff!

I didn't get that deep into comparison.

I found more specs for my unit here: http://www.aliexpress.com/item/Free...itive-Touch-Screen-1080P-WIFI/1898813082.html

Definitely looks like it's a match.

Checked out szklyde store - somehow the only units he has for cx-5 are android 4.0 with 1Ghz

Good question. Well, there's a guinea pig now (me) that is gonna try to find the answers.

Maybe this will fork into a completely different thread

Here is a link to the video I sent my seller about the canbus issue that my setup has, anyone else have this or know a solution?

http://youtu.be/rLQr-X5AyKQ
[MTCB Android Head Units Q&A] agentdr8:
I've read through this whole thread and am thinking I'd like to pick up one of these to tinker with. Can anyone tell me if the built-in bluetooth supports SPP? I'd like to pair the HU with my Valentine 1 (via BT connection) so I can utilize YaV1. I'm guessing it does, since it can do bt OBD2 to Torque (right?), but I just wanted to verify.

Also, which seller(s) on Ali are best to deal with in single quantities? I'd rather avoid the issues that some had with units from Green Point.
[MTCB Android Head Units Q&A] cat2115:
You are right. It's not working, kept on force close. Could you or anyone hack this iPod to work if possible. Thanks.

Or can we use AN-21 iPod app for our unit?

What is the best device for selection when using MarketHelper?
[MTCB Android Head Units Q&A] lucky-jon:
Sorry if this is nothing to do with your issue, but just in case!

To my knowledge, there are at least 3 variants of canbus on VW.

Are you using a canbus adapter supplied with your head unit? I have a VW Transporter / Multivan, 2007. The vehicle has no accessory power wire, just permanent 12v. The head unit I have needs 12v perm and 12v acc to power on. If my vehicle had an accessory power wire, it would be very easy to install, but the stock head unit uses canbus messages to put the stock head unit in and out of standby. The purpose of the canbus adapter is to read data off the vehicle's canbus interface and recreate signals like Accessory power, may be reverse (for rear camera input), dash illumination, speed pulse etc. On the canbus interface I was supplied with, the orange and red wires between the two main connectors were fitted with a small plug and socket. This allowed the head unit to get its inputs directly from the vehicle or use the recreated version of that function from the canbus adapter.

In addition to recreating these signals for the head unit, the canbus adapter can also read steering wheel control commands off canbus, and convert them to analogue / resistive signals used by the key1 / key2 inputs on the head unit.

I think that the VW canbus adapters supplied with these head units are for the newer canbus 2 messages. I know this is not compatible with my vehicle. I think mine is the same as Golf mk 4 and for my vehicle year models 2003 (ish) - 2010.

The head unit has settings concerning Canbus in the Factory Settings menu. I do not see how these settings can have any effect on the external canbus adapters being supplied as there is no data path from the head unit to the canbus adapter. My guess is that the MCU and other hardware / firmware in the head unit has been designed with the possibility of installing the canbus interface inside the head unit.

Hope some of that helps.
[MTCB Android Head Units Q&A] Blaze Falconburger:
I'm incredibly tempted by one of these units to replace my under performing Parrot Asteroid.

Where is the best place to buy in the UK?

How is Android or the music app at handling large volumes of MP3's via USB? I don't want to use a library based system, just browse the files/folders on the disc. This seems to be a limitation of many head units for some reason.

I like the look of the E46 version - where have people got theirs from in this thread?

Thanks
[MTCB Android Head Units Q&A] kwalsh24:
yep I'm using the canbus that came with the radio, my car is a 09. I lso too have that same connector that basically bypasses the canbus and sends a direct signal to the headunit, but my car like yours doesnt have a 2v accessory line. I've sent the seller my video which I posted on here, one time they say I don't need a canbus adapter as my car doesn't have steering wheel controls, the next they say I do.

Its as tho the radio when on the 'accessory' option at the ignition, will run for so long, detect that there isnt a signal coming from the canbus system then shut down. Meanwhile, my stock radio would stay on till I opened the door, same with the radio I just replaced with this unit.

Ive tried to change the factory settings but that didnt change anything...

Lucky-john, how did you go about your issues with your 07? Did you replace the module?

I'm hoping to resolve this issue soon so I can start to mod the unit.
[MTCB Android Head Units Q&A] Viper87227:
I ordered one of these two weeks ago to replace my PAS... finally got fed up with it's quirks and general slowness. Hopefully my unit will ship soon (I was told expect a 2-3 week ship time). Once I get it, I'll post about how the transition from one to the other went. I had high hopes for the PAS when I bought it a year ago, and it turned out incredibly disappointing.
[MTCB Android Head Units Q&A] Blaze Falconburger:
I'd be interested to hear how the transition goes - this is more like the unit the Asteroid should have been, albeit in single din format.

I was an early adopter of the Asteroid and have suffered for 2 years or more now - why they didn't just open source it and let the community develop it further I don't know. I had been looking for alternatives for a while and wanted to see how these units panned out - they look OK so far. My major concern is the 3 band equaliser which seems limiting and hopefully can be modified.
[MTCB Android Head Units Q&A] kaween:
I was wondering about that too as I'm looking at an AN21-U myself. (Tiptoes to the AN side of the forum with this nuget) :D
[MTCB Android Head Units Q&A] lucky-jon:
I dealt with a UK supplier called Dynamic Sounds in London, UK. The guy I spoke to was called Mem and the canbus interfaces are made by Connect2, another UK company. I can't say much for Connects2, but Mem seems to know their products better they they do and he was very helpful. There are three Connects2 interfaces for vw's CTSVW001, 002.2 and 003. The Seat part 001.2 is the same as the vw002.2. Google Dynamic Sounds and Connects2 and it should come up.

I could not get 12v Accessory, just 12v ignition - but I have been trying to get Connects2 to fix their firmware to keep the accessory line on until the key is fully removed.

I don't think most sellers really know much about specific installs - just the products they have for sale.

Good Luck!
[MTCB Android Head Units Q&A] kwalsh24:
Yeah, I've Gwen testing the canbus unit, and it is indeed the same, thw red accessory power wire is turned off after a few seconds of engine off time. I tested it by tuning a test light to the wire, and yep its the canbus doing the dirty work.

So my next idea was to try and find the power at key wire at the ignition and remove the red accessory wire from the canbus adapter and run it to that ? I've seen that on a couple forums and it appears to work.

I'm also going to see if there are any other pins on the canbus that remain on till key is removed. If I find one iI may try to relocate to that pin.

Attached is the sticker of my canbus adapter.
[MTCB Android Head Units Q&A] kaween:
Probably not. I don't have an AN21 myself, but after a bit of digging I found the AN21 mcu is in fact an STM chip, and not a Microntek MCU like in the Huifei. Bummer. :(

I suppose I still have proceed with my own Gala project then (capturing the speedline, sending it to an Arduino board, recalculate the result and send out Volume control signals/modifications using the SWC interface itself). Ah well.

Hello Kalle. I immediately installed the ROM and the MCU files provided by the seller and since then the problems started. The MCU file of the seller is: MTCB-KGL5-v2.22, then later I reinstalled the ROM using the file: MTCB-KGL-v2.09. In both cases does not work anymore.

I am afraid I do not understand the first part of your post, are you saying a speaker does not work?

What car do you have ? Not all car's CAN Bus systems are fully supported, so you may not get the extra functions on your unit.

You do not need to back up your ROM as we have copies of original ROMs, for rooting on 4.4.2 and 4.4.4 you need to install a pre-rooted ROM, the first page shows where to download and how to install a ROM and an MCU update, it is very very easy. The recovery image is is you want to install TWRP. You only need a 1024x600 ROM if your unit has a 1024x600 resolution. Use Google translate to read the first page completely.

Read, the thread or do a thread search - BT OBD works in 4..4.4.

Car stereo or car?
[MTCB Android Head Units Q&A] typos1:
Legally most countries require the stereo not to be able to output video when moving, the brake wire is used so the stereo can detect when the car is stationary and play video, but in factory settings you can turn this off and play video when moving. You do not have to connect the brake wire.

Maybe try swapping reverse and brake around ?

Music information on the trip computer is totally irrelevant to the brake/reverse wires. It may be that you car is not supported CAN Bus wise or that you do not have the right CAN Bus setting selected in factory settings. What car is it ?

Or you have misunderstood things ?

OK so my "power Injector" for the radio aerial arrived and was fitted and now I have FM (with station names on buttons) and AM stations as well, obviously the one provided was either faulty or just wrong.

Still many questions about this unit after a long play while waiting for the aerial connector:

All my connectors are via headers out of the back of the unit (except GPS antenna)

1) USB/3G dongle input - I have two of these - no matter what I do I can only get the unit to recognise 1 USB stick. Is this a limitation? Can it be overcome by rooting? I do not have a 3G Dongle to connect!

If I use a 64Gb stick the unit recognises it and will play music/video for a couple of seconds then dismounts the stick - is this due to the 32GB limitation?

2) Ipod input - How does this work? plugged in Ipod and went into Ipod app it just exits the app without reconsigning the connected device - what am I missing?

3) Google Now - apparently there are issues with the current version - what version works and where can I get it? - the installed version is version 3.9 (Google Search) which only works from the Google app screen, I really would like voice commands working.

4) Can I change the stock 5 icons on the bottom of the screen - again has this been done by rooting or via another app?

I would like to take a backup of the installed MCU and Andriod before attempting to root so I can get back to where I am, any info on how to do this seems not to apply to my unit as it is a Klyde KLDS07 with no micro usb port - Is there another way without installing a pre-rooted o/s?

With over 1000 pages and 10000 posts in this threat it is really difficult to find information - can this be split done into sub threads relevant to specific topic i.e. hardware, rooting, etc?

Any help with my questions would be very welcome

[MTCB Android Head Units Q&A] Siffion:
Hi. The USB issues are most likely power issues to the USB ports. Can you try with a powered hub.

Go into the hidden options menu code is 126 and see if IPOD is switched on

No need to backup MCU as they are all available ref the link on page 1. Just make a note of what's installed at the moment so you can rollback if needed.

Same with the rom, iirc you need root to run titanium pro or similar to create a backup. I may be wrong though.

Icons at bottom of home screen can be added and removed, just remove the old by dragging to the trash can. Add by holding down new icon and place where you want it to stay.

Google voice, I'm also having Google app crashes so if anyone else can assist here it will be appreciated
[MTCB Android Head Units Q&A] Wagy:
OK Thanks for response IPOD now working although it was a bit more basic than going into factory settings, as I said all connections are via headers at the back and it appears you can connect the cables into the wrong header! :cowboy: now all sorted for IPOD music :good:

Anyway after taking this closer look at the headers I found one is actually called rear USB - I haven't been supplied with appropriate cable/header plug but I will investigate if this can be used I can probably make a cable easy enough

I did try a powered USB hub with 3 sticks in it, worked fine on PC all 3 sticks mounted but only one stick is mounted on HU, same thing irrespective of which USB/3G port used no idea what's going on here, obviously other units are OK, I did only use a 500mA power adaptor but this should be enough for a couple of sticks.

Thanks for the home screen Icons tip all happy here too :good:

I believe the on-board flash must have a backup of MCU and Andriod so maybe I will just put the rooted o/s on as I should be able to get back via recovery console.

It's probably an inductor, not a capacitor, since the designator is "L". Can't tell from your photo, but are there any numbers or anything printed on it? That would help determine its value.

[MENTION=6045678]mikochu[/MENTION]:

Uhgh, looks like you lifted the pads. Are they still there or are they attached to the smd inductor?

You have to be really gentle with surface mount parts, its easy to rip the pads.

If you are a noob with a cheap soldering iron, you should get some solder wick or a solder sucker and some chip quik. Melt the solder, remove as much as you can with the wick or sucker. Then apply some chip quik. The chip quik will stay molten long enough for you to melt one side, quickly melt the other and remove the part. You may have to go back and forth a few times. Tweezers or a chip popper would be helpful.

Id ask the more knowledgable people about a good guess on the value of the inductor or if someone can measure it.

Some Klydes do have RGB LED. RGB LEDs are not an indicator of who makes your unit.

[MTCB Android Head Units Q&A] RyanBRZ:
Yes. Think about how it works normally. It gets signal to the trigger wire when you put your car in reverse. You will just need to put a toggle switch onto a lead to make your hu think its in reverse when you flick the switch.
