[MTCB Android Head Units Q&A] typos1:
There is a free version.

No probs :)

Klyde sources and supplies them.

They are all on the fileserver as the first page says.

No need, I put all the launchers on the fileserver.

No, not possible on KK.

You could change the amp IC for the Toshiba TB2929 one that the Roadmaster versions of these units use and also the AN21-U, it only costs about $5.

HuiFei is KGL's brand. All the companies make their own units using the same SoMs and the same software devs, none modify HuiFei/KGL units. MCU names use shortened manufacturer names - Kai Ge Le = KGL, etc, you would need to find what "MX" equals. Witson is a reseller yes. The HuiFei/KGL site uses a slow Chinese server, better to go on their Alibaba/Aliepxress site. The MCU chips are the same AFAIK, they just use very mildly modified software.

Glad youre enjoying your unit ! It isnt actually a new one though, its just a KGL quadcore unit, bet it was a pleasant surprise you got a quadcore when you were expecting a dualcore ! Try holing the power knob for several seconds to get into recovery or install the "quickboot" app if youre rooted.

As I mentioned a few weeks back, KLD are about to start making these units with DAB tuners, apparently they arent retrofittable though, unfortunately.

I also mentioned a few weeks back that KLD are about to start selling these with BT TPMS as an option (TPMS app is in the OEM folder on newer ROMs), theyre still testing it ATM, so no more info yet. You could try the same tricks to get Torque to work with a BT adapter, cant remember what this is but [MENTION=434511]agentdr8[/MENTION] will know as it uses his app.

As the pdf on the first page says, KGL and Roadmaster use the NXP/Phillips radio IC, JY use this as well, KLD use the TDA7706 chip (pdf needs to be updated).

You have an AN21-U, try that thread.

Glad you finally got it sorted ! :)

What screen res do you have ? 1024x600 should automatically have the 2 pane set up, I ve tried using xposed to change it to 2 pane on an 800x480 screen but it doesnt work.

Settings/extra settings.

As has been discussed at great length in the thread before and as mike.s says, the power injectors sold as "boosters" only work if you have an OEM booster, they do nothing if you do not. They shouldnt be sold as "boosters" but thats another story. I ve read that they contain a power injector AND a filter, as theyre only a few dollars it may be worth trying one with one of the proper boosters in the hope that the filter in the power injector filters the static thats amplified by the proper booster. If there are problems with the power injecting part that could be disconnected so just the filter works.

Front USB, if you dont have one you cant.

Klyde have tried apparently several times to upload the latest firmware but they say it keeps failing, so they are going to send it to me. I ll keep you posted . . .

The main difference between the firmware is the launcher and as the firmwares are compatible between units, you can simply install a KLD or KGL ROM and change the launcher to the JY/KYD launcher, problem sorted.

Theyre on the fileserver.

So do I, just gotta wait for this new firmware from KLD.

Are you using Malaysk's ROM ?

You have an AN21-U, so youre in the wrong thread, dont think you can upgrade to KK, but theyll tell you in that thread.

Its been confirmed by 2 manufacturers that Lollipop will be coming to these units at the end of the year using the RK3288 processor - the RK3188 is not Lollipop compatible.
