Not really,I live in the UK . It cost me £16 a month for 10 gb of data on a one month rolling contract. If I decide to leave just after a month the wifi is mine. Yes probably a little bit more expensive than a usb dongle, but it depends on how much you want a hassle free data connection I suppose. Just an idea anyway and if am using little data I can just get pay as you go sim with x amount of data on which will probably cost a lot less.

superb

thanks wokro for figuring this out.

i looked all over the internet for photos that matched my head unit and until recently almost gave up on the HU completely as receiving calls on bluetooth is important for me.

until i found wokro's post 10685 people could not even make out what i was saying on bluetooth calls before. now it is is working well. :)

i followed wokro's notes on where to solder in an external mic and added a new 3.5mm mono socket at the back of the HU. i ended up soldering the mic ground to one of the grounded pads next to the vertical BT board as my soldering is not great.

I'm sorry, I searched ebat.it

in fact the description is a bit smoky

says win ce6, android 4.4 and 4.1 seems on some pictures

however the louncer in the images is the same as mine Klyde 4.4.4

the seller declares on the ad:

· OS: Android 4.4

- Nand(flash): 8G

- HD: 1080P

- Storage memory： DDR3 1GB

- CPU: A9 processor with Dual- Core

seem RK3066

as all sellers have avoided showing the version of MCU

does not mean that this is the item you are looking for, but with a little patience you can find the right item :)

Update to 4.4.4 than this problem will be solved. I had the same issue.

I contacted tomtom, but they couldn't help me. Haven't found any other solutions as well.

By changing to 4.4.4 I got root as well.

With the xposed framework with the AppSettings module installed you can change the size of the tomtom app.

Just this morning when I've re-soldered the SGND on the BT unit as you recommended, I've realized that you've been really modest with your opinion.

I think your missing the (/mnt/internal_sd) in front of /data/data/ just like the tomtom above it. When its working right you can go to mnt/internal_sd/data/data and then when you go to com.slacker.radio you will see the disk space change to your external drive. Worked with here maps perfect with me but I had replaced the tomtom line. DSA I believe said you could run more than one line. He will have to confirm. Good luck

Thanks, maybe I will try replacing the lsd line for tomtom since I don't use that

I don't think the native installation for slacker is on /mnt/internal_sd/

If you look at my first picture, you can see the location and it is simply /data/data/.

The original install is on the smaller partition, of my nand, not the "internal sd" which the system treats as the internal sd.
[MTCB Android Head Units Q&A] fareed_xtreme:
Appreciate your detailed answer. Now I know that my unit (which is en-route from HongKong) is actually a variant of the JY and uses the JY ROM. So I guess this is the ROM that should be rooted and safe for my device?

[MTCB Android Head Units Q&A] markcm:
I made a (/com.slacker.radio/) directory in two places, one was on the data partition of my NAND (/mnt/internal_sd/) which in my case is 12GB because my HU came with 16gb NAND.

Ok so I installed the latest Malaysk rom on my rk3066 and it is way more sluggish and unresponsive than the old coudu rom I had on there. I updated the MCU at the same time. The apps I have are all the same versions as before so no change there. Only change was to the July 7 update from Malaysk. It's a nice looking rom but it's painfully slow, especially at boot. Could there be something wrong with the install? Or perhaps something i can do to remedy the situation. The only thibg i had was a failed to mount meta data before the install began, could that be anything that caused this major slowdown? Also some apps just fc or run super slow. I even had all the same mtc apps and xposed modules as this rom, and only updated to regain extra settings (sleep acc setting) . Any help or ideas are appreciated.

Until [MENTION=6041319]dsa8310[/MENTION] straightens us out I would follow his instructions in post#16156 using your paths. Only make one target directory, delete all the others. Copy data from /data/data/com.slacker.radio to your new location. Delete that directory. Use one lsd line.

lsd "/data/data" "com.slacker.radio" /mnt/external_sd*/*/ (or /mnt/internal_sd*/*/ if thats where you moved it)

Thanks in advance!
[MTCB Android Head Units Q&A] jeroensteinvoorte:
If you de solder the condensator you effectively disconnect the bleutooth mic in from the rest of the unit. So you have to solder a wire directly to the bluetooth module. So you keep interference and other noise generated by the unit away from the mic in.

Different KLD2 MCU versions and radio issues

As mentioned before, the latest MCU image for KLD2 board is 2.67.

Mine board came with v2.55, so I updated the MCU to the newest version.

Now I reverted back to v2.55, and it works again. :)

3g dongle issue

Hi,

I bought this dongle which uses qualcomm chip (don't know the dongle brand) :

http://www.aliexpress.com/item/2014-HOT-selling-7-2Mbp-3G-Wireless-Modem-HSUPA-usb-modem-Qualcomm-6246-with-EDGE/1952230438.html

When connecting it to the hu (KLD using malayks rom) I can see the cellular signal but the I get a triangle with "!" saying voice call and data restricted (or something like that).

How can I solve this?

Thanks.
[MTCB Android Head Units Q&A] The_SilverOne:
no but I saw the install erased /data. I had no apps nor anything on there when it booted for the first time with the new rom so I thought it the factory reset was not necessary.. is it something i should still do even though during install /data was erased.

Here is my progression with roms

STOCK with stock launcher

coudu with stock launcher (then installed nova launcher)

Malaysk with next launcher (with nova launcher as default launcher)

The first two were stupid quick and almost indiscernible between each other speed wise. The Malaysk rom is painfully slow. I used to get in the car start it and drive off with music playing within 45 seconds at the most. Now it takes minutes to boot and minutes to run through its start up. Also some apps like Dailyroads do nothing but FC on me.

FYI all user apps were reinstalled after the fresh install and are the same versions as used before (just so no one thinks I was lazy and just updated the ROm without doing much else)
[MTCB Android Head Units Q&A] jperezch:
The software of this units comes in two parts: the MCU and the Android itself.

The MCU part is manufacturer specific. In your case you sholuld stick to HA versions.

The Android part is processor type and screen resolution specific. You can install any version whenever you choose one for RK3188 1024*600, no matter the manufacturer.

The most up-to-date and complete firmware versions are Malaysk's ones. He uses JY launcher and apps in his latest versions.

You can get them from the following links:

FreedomePop in USA

Has anyone used the head unit with a Freedomepop Sim Cards in USA?

Freedome pop is based on the 4G LTE CDMA network of Sprint and they offer free accounts for 500mb to 1GB per month

so I am not sure the USB modems that go arround are compatible with CDMA 4G network .
[MTCB Android Head Units Q&A] markcm:
I ordered a freedom pop hotspot a month ago, it just shipped today.

Be aware, the free service is not LTE, it is WiMAX which has very small coverage areas and is being phased out later this year.

I paid about $4/mo to get 500mb of 3G service on mine.

Sprint service coverage in the Pacific Northwest is really poor...

Well, I obviously can't hear myself, but those I've talked too say its a big difference. I'm taking their word for it :fingers-crossed:

It was a breeze to put in. Its a 3.5mm plug, same as the head unit. The cord was long enough without the need for extension. I clipped it to the driver side sun visor. I ran the wire under the seam where the roof meets the widow, down the passenger side a pillar, and then came back up under the glovebox and into the radio. I had maybe 6 inches to spare, so it was close, but it made it.

Well, least I'm not the only one, I'm thinking it's software as it works fine on SD music playback, just not on tuner/radio playback
[MTCB Android Head Units Q&A] agentdr8:
This is probably right. After futzing with my Xposed module for hours last night trying to override the ModeSwitch() method, it became apparent that the hu keeps track of which audio channel is active. It does this by storing a parameter in an instance of AudioManager, and when you cycle or change foreground app, those apps set the value to something else. So far I've managed to get nav, radio, and Poweramp all trying to output sound at the same time. Wasn't what I was going for, but it means I'll have to look closer at how the MTC apps switch audio channels.

One possibility of why it's working with SD music and not radio is that the av_channel for music is "sys", as it is for nav, or any other Android system sound. It's using stock Android input mixing for nav output at this point. Once in radio it switches to "fm", and uses the app defined in Settings->GPS as the GPSPKNAME, which it then searches running tasks for. If found, and mixing is set, it's supposed to adjust the current av_channel volume by mix value, and play the nav output on the sys stream, overlaying the two. Since it detects the gps app fine in "sys" channel, maybe there's something wrong with the MTCRadio app.

Communication with KGL?

Hi all, new user here.

After reading about different sellers, I got the impression that Kai Ge Le is a reputable seller, since they also manufacture the HuiFei units.

So i got in touch with their sales rep Keylo, who is also on this forum.

Since their Alibaba store is for wholesale only, she referred me instead to their Ebay Store, which they just recently opened:

Search for the seller called "carparts852" on Ebay.

The person in charge of their Ebay sales is called Dana. I found the model I wanted among their auctions, and sent an Ebay message asking for a shipping quote (including optional items like reverse camera, DVR and DVB-T2).

This is when the whole deal stalled. I get no reply through the Ebay messaging system, and Keylo doesn't answer any more.

Has anyone dealt with them recently? Maybe it's some kind of public holiday and nobody is checking their mail in China???

I know someone on the forum was dealing with Hanker Yu, he's a colleague of Keylo. But I don't get any response from him either. Any other way to grab their attention?

In all seriousness, they're sometimes responsive, and other times not. Single unit orders don't make them any money, so I'm guessing they have less incentive to respond. It's good they setup an ebay store though for consumer purchases. Maybe give it a few days for Dana to respond.

Hello community,

I tried by all means for asking my seller how to connect my unit to the PC, he doesn't have any clue, now i am 100% sure there should be a way else how did they program it in the process of manufacturing?!

My unit is KGL-7610 it is a Universal HuiFei Unit, can someone just inform me if there is any way for connecting the front USB from the board directly? which wires are needed to be soldered?
[MTCB Android Head Units Q&A] agentdr8:
Mine is also a universal (even though I ordered a Nissan-specific part; oh well) without front usb. I haven't had the chance yet to take the faceplate off, but my theory is that the miniusb is either still there, just behind the faceplate, or the solder pads are still there. I can't imagine them assembling a unit with it to do the initial flashing/programming, and then desolder it from the board.

If you manage to get yours apart, take some high-res and well-lit photos of the board behind the faceplate. We can figure it out. I hate testing mods on my unit without having access to a custom recovery.
