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 Questions before touching new unit

Hello guys,
I just found a local shop in my country for head unit and they installed the unit for me.
Everything was working except the 360 camera but they put a relay and now it's fine.

I would like to change the interface I really don't like it,
I tried different Car Launcher but still not very happy..
I prefer to ask if it's possible before crashing everything (I did a backup in case)
I don't have any information about the vendor
Then if I understand I will have to choose between Mekede, Joying and Teres
Thank you for your help

FYT = 1

Yes I found that in the backup I did with your apk
So it means that I can proceed ?

You can just install launchers and uninstall them if you don't like.
You can toggle between the home launchers also in the apps default.

Im looking for something customizable
For exemple I’d like to see my km range on the main screen or the average consumption.
Also for the speed, it use the gps value but is it possible to get this value directly from the car ? Same as the rpm

launchers are the way.
I like AGAMA but CarWebGurus has good support and customizations as well as Fcc CarLauncher or Car Launcher (free/pro)

Thank you I will check them out !

I have the exact same unit. What is the brand and model of this unit?

There are no 'brands' only made up sellers of various chinese origin factories. FYT =1 according to first post

Support desired px3 update

Hello,
First of all, I would like to let you know through this way that English is not my native language and therefore the sentences and words will not always be fluent.
Secondly, I don't know if I posted this question in the right subtopic. Moderators, please feel free to move this question.
I recently purchased a 2012 Volkswagen Polo. This, when purchased, already had an Android tablet built in. I have no idea what model tablet it is but I have the following information available:
Model:
px3 (1024x600 O)
Android version:
7.1.2
Level of Android security patch:
May 5, 2017
Kernel version:
3.0.101+
[email protected] #894
Thu Jan 25 18:26:25 CST 2018
Build number:
px3-usrdebug 7.1.2 NHG47L eng.hct.20180131.123949 test-keys
MCU version:
MTCE_GS_V2.83_3
Apr 13 2018 21:00:04
CPU:
ARM Coretex-A9 @1.6GHz (x4)
Memory:
2048 MB
I was curious if I can find a newer firmware version somewhere for this tablet incl. instructions on how to install it.
I have sporadic problems with the radio (it sometimes goes louder unwanted or forgets my set favorites). In addition, I see several videos passing by where the interface is just a bit more slick and updated.
Can anyone help me with this? Thanks in advance and apologies if I seem a bit stupid / ignorant (I am however an ICT-er so I understand somewhat how certain things work).

You might be better off replacing the unit.
You could replace the SOM with a PX6 board (4gb+ ram) and then upgrade to Android 11, but these MTCx units remain behind on what is offered by the FYT units with UIS7862 processors.

Question Seeking advice on flashing alternative software to "Nevegetor" HU

surfer63 said:
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.

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.
