  @Dasaita Official  @Dasaita team @James Varney i just received the G12 unit under order:SP-DA4438, i follow the installation instructions, my car is Toyota corolla 2015 model ZRE171L-GEPNKV, i have the following issues

  1- reverse camera not working and the screen not responding at all even the black screen with yellow triangle not show up, i attached the camera power cable in the reverse light and the vedio cable to yellow CAM-in cable and triger cable to car back cable as shown in attached vedio

  2- the steering wheel control not working

  3- the AC & door indication not working

  4- External MIC not working ( select between Internal & External became avalible after the update), i do a test using voice recording app, Internal Mic resopnd when recording and the External Mic not

  i review the frequent problems in the page and i found that may be if i update the firmware and MCU the problem will be solved , so i update the firmware using 20231229 and the MCU MTCH_HA4Z_V4.09b_1 ( i will attach the system photo after updates)

  attached also the settings for the canbus

  still the same problems not solved

  i still waiting your replay, i can afford to loose the function of the door open indecator and AC information , but the steering wheel key, External MIC and the camera can not be comprmissed , may be the Canbus is not working !! since i can figur out that all the problem ( except the MIC are related to comunication between the new headst and the car data which mainly the canbus roll, at least let me know if there is any test i can confirm if the problem related to the canbus or othere programing issue  , if it is the canbus, i can search the local market for alternative canbus 

  resently i review the wiring

  for the MIC: i disconnect the cable and connected again, then increase the volume in the factory siting

  for the revirse camera : i disconnect the trigering wire from the car back wire still can not see the camera vidio or the black screen with yellow ! mark

  for canbus: i disconnect from the cable and install back, select wrong canbus type and reboot  then select canbus number 8 for corolla and reboot agin

  for steering wheel control, i Go to Facory seting => Other => SWC => NO, reboot then select SWC Key => reboot again then go for manual SWC  programing, the list is blanck

  @Muhammad Fadl Please ignore my message in the morning. Regarding to the back camera. Please kindly remove the connector(See the attached pic) 

  If still no luck, we are wondering if you could check if the connection is the same as this video.

  https://www.youtube.com/watch?v=CnkfOYrUrqw

  As to the Mic, we would like to tell you that the Mic settings in Factory settings > other is not available now, if you need to check whether the internal or external works, you need to unplug the external mic to activate the internal one.

  Regarding to the canbus, we are wondering if you could check the pins on the OEM canbus and swc plug. Would kindly send us photos of this OEM plug so that we could check if these pins have according wires on your car which could activate the functions as well.

  Thanks for your replay

  my car originally did not come with OEM CANBUS 

  for the reverse camera, i remove the connector as you highlighted, i cut the orange cable come out from the power cable and connect it again with the triggering cable of the camera cable, then the camera worked fine

  for the SWC, i used the two additional wires ( key 1, Key 2) with one brown cable from the power cable set to connect it with the car connector, the manual assign for SWC activated and work fine with me now

   

  

  for the MIC, i try to follow up the recommendation in the post (ZLink Microphone with Apple CarPlay Issue) where we should  use the firmware 20240111 update to solve the internal MIC bad quality and External MIC not responding, but unfortunately the update gave me error ( error image attached)

  i hope to solve this problem since the apple car play is useless with bad quality internal Mic, also i cannot figure out how to connect the iPhone Bluetooth with the unite without activating the Zlink (apple car play), every time i connect the iPhone to head unit by Bluetooth, apple car play automatic activated and when i close it and try to connect the phone Bluetooth, apple care play start again

  for the Door opening & AC indication still not solved

  for the car fuel consumption and trip data still not reading

  @Muhammad Fadl Regarding to the update, please kindly format the USB to FAT32 before putting into the USB stick. You should make sure the name of the file if "update.zip" and it has been put into the directory of the stick. 

  If still no luck, please kindly try to switch to other USB ports or use another stick.

  @Muhammad Fadl Regarding to your issue about the GPS, we are wondering if you have connected the GPS ant in a correct way. Normally, we suggest you wire it on the windshield. Here is the instruction.

  @Muhammad Fadl We are wondering if you could print the log of the GPS disable and then scroll back to the previous firmware to verify the issue could be resolved or not.

  Here are the steps of the LOG printing.

  1.Please go to settings > Car > Factory settings > enter "logcat" then go to the GPS monitor to check the GPS. 

  2.Return to the filebrowser and copy the log file.

  Here is a previous firmware version.(20231229 version)

  @Muhammad Fadl We are wondering if you could record how the internal Mic work with nose. In this case, we could forward to the engineer to check if it's software associated or hardware associated issue. Your cooperation will be appreciated.
