Could anyone here clarify exactly what files need to be on a FAT32 formatted USB drive in order to update? I have downloaded HOLDEN_KS_Auto_DSP_0219.rar and alfa_v3.2.2.zip
It appears that the contents of the RAR should be copied to the root of the USB directly, but then the instructions show a vehicle specific ZIP file that should be there as well, and it doesn't look like alfa_v3.2.2.zip goes anywhere? Thanks!
I confirmed via chat messages with the Kremersino store on AliExpress that only HOLDEN_KS_Auto_DSP_0219.rar is needed to update the firmware. No need for alfa_v3.2.2.zip - not sure where that came from.
So for future reference, I found a 1GB USB drive formatted to FAT. I simply copied the contents of HOLDEN_KS_Auto_DSP_0219.rar archive to the root directory. With the Ksmart unit powered on, and the OEM screen switched over to the Ksmart side, I plugged in the USB drive and I was prompted to update right away. After reboot, I see now that HOLDEN is the boot screen.
Then, I needed to re-pair my phone via Bluetooth since the device name changed. On my Pixel 7a once paired, I have Phone Calls and Media audio selected, but no access to contacts and call history.
These are the settings I am using for future reference. Bold are changed from default values:
System version: Linux_3.4.0_2023-12-05
MCU version: gm09_3.1.2_305_7_255_0
General:
- Volume = 30
- Navigation Volume = 25
- Auto Start Phone Link App = False (Preferred since I need to switch back over to OEM side to turn on stereo after Bluetooth turns on and connects to phone)
Car Setting:
- Reverse Camera = OE Camera
- Front camera time out = 0s
- Steering camera time out = 0s
- Dedicated right view = Off
- Reverse Guidelines = On
- Reverse radar = On
- Car type = 1
- Display type = 1
- Sound type = 1
System> Factory Mode > Phone Link Settings:
- Android Link Type = USB && Wireless Android Auto
- iPhone Link Type = USB && Wireless Car Play
- Mirroring Link Type = Wireless Mirroring
- Right hand car driver = false
- Disable Phone Link Audio = True
System> Factory Mode > Reversing Camera mode:
Lastly, navigate into Bluetooth menu/section on the Ksmart side, there is a
check box for Auto-Connect, ensure that is checked so that your phone will connect automatically and be ready to start Wireless Android Auto when you select it (if you have Auto Start Phone Link App = False in General)
I'll update again in a few days of daily driving... my one outstanding issue is having to manually initiate the Bluetooth connection to the Ksmart module from my phone in order to be able to get Wireless Android Auto to connect
Everything is working nicely (again) for me now! Just need to verify phone calls, Google Assistant and I will keep this post up to date with my findings.
