Head unit info
Abogrhen Sorry for being a bit harsh but you're not the first one that post without the device info. And this thing starts to be a habit among members. Some people don't understand that without "device info", the devs cannot help that much.
What is your vehicle model and is the SWC signal wire connected correctly?

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.

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

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
