Abogrhen This has never happened before, assuming it's a software issue and the learn icon doesn't disappear but doesn't work when pressed. Assuming the SWC button doesn't work, but nothing was done, just relearned and then worked again, being able to learn on proves the cable connection is fine, confusing me.
SWC button no response after sleep

I tried the shutdown setting
But no difference
Try using a CANBUS bus box to see if that solves the problem.

Thanks for the suggestion
But as far as I know
There is no canbus available for my car
(Hyundai elantra 2010 )
As it older model with standard ISO connection as the car came with JVC unit from factory and later on upgrade it to Kenwood unit
Before moving to android head unit
And all of them worked with SWC button
And as the buttons work fine when programmed it's clearly a software bug
Any way i have ordered my self the dudu Bluetooth remote to solve the problem for now
But i hope that you can flag this problem and try to get into it later on
11 days later
hy, im driving also hyundai ix35, 2012 (year of production - car model without CANBUS), only cable, i have question regarding head lights ON/OFF, doors ON/OFF (it shows on car command displey/desktop)...does lights on/off, door on/off only works with CNBUS, or it support some car models without CANBUS?? my swc works solid, only sometimes it dont show volume up/down graphic on screen, and and some buttons are slow to response but i think it is related to usage during years
It is not possible that your car doesn' t have CANbus.
CANbus is one of five protocols in OBD-II
2001: The European Union makes EOBD mandatory for all gasoline (petrol) vehicles sold in the European Union, starting in MY2001 (see European emission standards Directive 98/69/EC).
2003: The European Union makes EOBD mandatory for all diesel vehicles sold in the European Union
2008: All cars sold in the United States are required to use the ISO 15765-4 signaling standard (a variant of the Controller Area Network (CAN) bus).
See also ISO 15765-4.3:2001 “Road Vehicles-Diagnostics on Controller Area Network (CAN)—Part 4: Requirements for emission-related systems”, (December 14, 2001)
So, by law, worldwide, every car has to have CANbus for control of emissions.
Actually your car does not have "a" canbus, Most cars have 5-9 CANbuses connected to the several systems in the car.
What you proablably mean is that you ordered a unit without CANbus decoder.

Hi although you're replying to @obelix80
Your are correct that all cars have obd2 protocol connection nowadays
What we mean here is newer cars have a connection to the car radio that make it (smart) by getting some information from other systems
Like if the door is open or if the head light is turned on and many more
So need to decode the signal
So you use a canbus decoder
Unfortunately some economy older
Japanese - Korean cars think 2015 and older do not have that
And use simple ISO radio connections that not communicating with car at this level
My car came originally with an aftermarket style one din stereo
OK. I understand.
Your car simply does not have the CANbus Hi Lo wires (and some more) connected into the ISO plug, or si it seems.
Is it not possible via Hyundai or some other source to get an extended ISO plug?

I can't comment about the other guy
But for me
Adapter harness is pluged in
and have the prober connection
And it communicating with head unit
Also i have used an older unit and it works fine there
My only problem with this unit
Is after programming the key for the steering wheel
They work fine
until reboot or restart or deep sleep
They stop working
For now i have installed a Bluetooth remote control on the steering wheel that i got from dudu
I hope they can fix the issue

surfer63 or this one, description said it is responsible for comunicating about lights, acc, doors etcc... https://vi.aliexpress.com/item/1005006686987452.html?pdp_npi=4%40dis%21BAM%21BAM%2079.94%21BAM%2063.95%21%21%21308.64%21246.91%21%40212a6e3217347333249763523e79ce%2112000038015784139%21sh%21BA%21728591981%21X&spm=a2g0o.store_pc_allItems_or_groupList.new_all_items_2008437776057.1005006686987452&gatewayAdapt=glo2vnm#nav-review
but im not sure, i asked seller, and every seller i asked said to me to send him picture of my original car radio unit, and when i send him he said that they dont have canbus decoder for my car...so i find it weird....dont know why it is importanat original car headunit
If I turn off the device completely (turn off the ignition and remove the battery), will the device forget these settings?

Kriss Not necessarily. Depends on your vehicle, canbus/no canbus. These are some exceptional cases. If your car/head unit uses a can us decoder this sould not be the case. I don't know what to say about disconnecting the battery.
