Question Carlink change DPI?

I recently bought FYT based head unit that comes with wireless car play (reseller called Xima). the app for wireless car play is Carlink. default resolution is about 480p. the Carlink app setting page doesn't give much options beside noice cancelation mic channel, car logo, wifi 2ghz or 5ghz.
Is there any updated version that allow me to change DPI and key mapping?

I believe CarLink 2 is what comes with the newer units. Check with your reseller to see if available.
Mine doesn't have the option to change resolution though, you may have to go into the Android settings for that.

so I managed to flashed the head unit with latest Joying firmware and app. Car link upgraded to Car link v2. (v21.1014.1122 to v2.21.1224.1818, strange versioning convention...) UI looks the same. gained 2 new options: FPS and auto connection. all the icons still looks pretty big. and I still can't map the Siri activation button.
Used to have car play USB dongle, the software provide a lot more options, such as changing DPI and key mapping. maybe I should keep using the USB dongle until I can find a solution.

I also bought xima multimedia this year, it have carlink1.0, I was also looking to update car link to version 2.0. How did you updated it with Joying firmware? Can you guide me?

Seems to me Xima's firmware is just slightly modified version from Joying firmware (and they make it looks worse).
All the instructions are in this wonderful mega thread:

If you did it couple of times, it's pretty straightforward. and here's my TL;DR version:
1. pick one firmware from Joying website that matches your HU. I picked this one:
"...firmware for 9 or 10 Inch 1280*720 model with MIPI screen/New UI (As below example)"
Updated file please click Here
2. backup your existing firmware just in case and grab the configuration file:

after backup, there should be config.txt file that defines the screen orientation and Bluetooth type.
mine shows:
ro.sf.swrotation=90
sys.fyt.bluetooth_type=0
3. based on config.txt file extracted from backup, update the config.txt in the firmware package you downloaded from Joying, and make update, this would ensure the correct screen orientation and functional Bluetooth.
ro.sf.swrotation=90
sys.fyt.bluetooth_type=0
4. Get the Change reseller ID script. ChangeFytmanufacturer , This is for changing reseller ID.

Xima doesn't have assigned reseller ID, so use 1 (Joying uses 43).
ChangeFYtmanufacturer, /lsec_updatesh/7862lsec.sh
change 99 to 1
sed -i "25i ro\.build\.fytmanufacturer=1" /oem/app/fyt.prop
5. Copy firmware from step 1, updated config.txt from step 3, and updated /lsec_updatesh/7862lsec.sh from step 4, into blank USB drive. those files and folder should be in USB drive root folder.
config.txt
6315_1.zip (firmware)
AllAppUpdate.bin (softwares)
Isec6315update (for flash the firmware)
lsec_updatesh folder with 7862lsec.sh inside.
updatecfg.txt
6. Insert the USB into HU, The HU should auto detect the firmware update program. just confirm and let it do the work.
and that's it.

Hi, I also flashed joying's firmware recently, what's the password for factory settings?

I've tried 3368 and 126 and a bunch of other password.. no luck

to your question, you can set smallest width in developer settings, this will change dpi for all apps. For CarPlay I think the dpi might be fixed, it’s supposed to look this way. Not sure if you can really change it.

smallest width changed from 720p to 480p works great. finally I don't have to deal with tiny font-size. Thank you!
3368 works for me after flashed Joying's firmware. not sure why.

Finally figured out:
besides changing "ro.build.fytmanufacturer", "ro.fyt.uiid" also need to be set.
in my case, I have mekede m600s, I need to set:
ro.build.fytmanufacturer=116
ro.fyt.uiid=4
with these 2 parameters set, then 3368 works for me.

Question New head unit unsure of model number. Vendor is is Navifly/mekede

Looking for some info as I got a new head unit from a friend and was looking at how to identify the specific model number and features and update firmware.
HWget info has manufacter as 116 boardtype F, platform 6315
it has a sticker that says 9inch/836/4g/6+128/720/B1/CP
I know it is a 9inch 4g capable, 6gb/128rom, 720 screen with built in carplay
I don't know what the 836 and B1 mean.
Some additional questions beyond simply identifying this:
EQ says "surround sound has been closed" when you select the surround tab
Can you get carwebguru to recognize the BT player?
How to tell if this can support 360?"
can 360 be added (am conformable with soldering on the mainboard)
carlink 2.0 does not connect to phone
what is "plug in serial device setting? Has options "accelerator / accelerator3b / kq TPMS / serial plugin 360"
I thank you in advance.

Ok well that's what pops up when I copied and pasted the information you gave into Google. You can't say something isn't real when I show you proof contrary. Also if you can give more info like an MCU number instead of the vague HWinfo results people can actually help you pinpoint a specific model instead of "supposedly fake" head units.

Manufacturer ID =116 already limits it to Mekede/NaviFly, Prelincar, Hencheng, Yiling, Hopod, prelincar, coho (and a few more) where some of them use the "YIN" identifier in the firmware. So you could use a Mekede firmware which is still regularly updated (latest update firmware 23 September 2022)

What do you mean with the MCU number? The MCU in all the 7862/8514a FYTs is identical. The MCU firmware inside that identical MCU might be slightly different dependent on the hardware, and that is determined exactly by the manufacturer id (displayed by the "vague HWInfo" , which lists much more info inside the zip, when that zip would have been shared).
Anyway, OP can flash a Mekede firmware with manufacture id 116, or a Joying with id 43 where he needs to update the AllAppUpdate.bin to put in the right manufacturer id (and/or bluetooth id). You can get that info all from the HWInfo.zip files.
The model number is completely irrelevant for a firmware flash. 9" 10" only differ in having 360 camera software or not.
Only difference make the Tesla style units as they use a different screen rotation and slightly differently built android apks.

I updated using medeke firmware to latest and eq surround sound is fixed, as is carlink.
Still no idea if carweb guru can be used for BT audio control (as I do like the look of some of the themes)
360 cannot be added internally since the IC is not sold independant the unit. maybe I'll find a donor unit someday.
Still no 100% sure on the "plug in serial device setting" but I'd imagine that is used for teyes front radar, or some other accessories. I have seen some 360 boxes that have an RX line to an android head unit so maybe that is what "serial plugin 360" is? which would let me add 360 without the IC, since the box would have it.
Appreciate the feedback.

The android auto is different. I cant use maps and music at the same window. I attached a video to show you how it looks. No Split-Screen design for some reason. Maybe its related to android 10?
my questions are:
1. How can I make android auto to work regular? As I see in the pictures in the play store?
2. How can I force android auto to work on full screen mode?
3. Is there an update to android 11/12/13 for my machine? Im running android 10. Moreover, I can not find the check for updates options
any ideas? also attached the version of the machine
thanks

1) Android Auto currently does not support split-screen, only at very few top-market builtin AA screens. So certainly not on these units using a reverse-engineered CarLink apk. Android Auto is kept simple to keep it as safe as possible.
2) You can't. Android auto copies your screen to the head unit (or car builtin in screen). It will be more or less your phone screen. That works nicely on a normal 8" - 13.3" landscape unit, but not on a Tesla style vertical screen. (And why use AA??? You have such a nice screen on a fully functional Android unit)
3) There is no Android 11/12/13 for your unit. If you see Android 11/12/13 units for the FYT7862, then they are fakes.
Please first read post # of this thread. Based on your question 3) you did not much reading yet. That is what this forum is for. Learning, not only asking.
Last summer Google announced that they are working on a new AA, together with Google Assistant, for many type of screens (as more cars get Tesla style screens) and for split-screen. I have no idea when that gets released and whether the FYT CarLink.apk will support it.

As far as I know: not yet.
As far as I know that is currently only available on a very selected set of built-in car units that support AA.
For my work I also regularly drive rental cars and all cars do have AA builtin (as they are never older than 1 year), but none so far with split-screen.
And please don't use webp images. The forum can't show them so I first need to download them. I don't want that.

Via AA, or directly and only connected via Bluetooth?
If you simply have your phone connected and play music on your unit in the Music Player via BT, it should simply work.
For AA via CarLink I don't know. On my unit I never, ever use AA: what a waste of such an expensive unit with such great funtionality to use it as an AA unit. There are special AA /CarPlay Android units below 100 euros for sale on Amazon and AliExpress, and these do it wirelessly as well.
I only use AA in rental cars.

UP

The App on the head unit is a hacked app written by the Chinese so they do not have to pay any royalties/licencing fees. Android Auto is written only for supported Head Units using unhacked software where the maker pays the correct fee.
So every change on the Official Android Auto app does not consider what effect it has on a hacked app, so if it stops working you are reliant on the Chinese hackers fixing the hacked app. Hence no reply to your request and why I do not use Android Auto on these units.

Hey there, @surfer63 !
I just purchased this 2k resolution 8GB RAM and 128GB ROM model from “Nevegetor”. The unit seems to be a newer style with a nicer, fuller screen and such. My question is - can I flash a Mekede firmware, as the UI that comes from this distributor is a bit bland? The unit should arrive in January. I am also going to need to figure out his to use my OEM camera in my 2018 Hybrid RAV 4.
