Can check if InstructionList.find could help.

Eventually for a proper navigation would need some maths and knowledge of route geometry vs user location.

Please can you explain how I can get the current instruction based on the user GPS location.
Any time I used the instruction.find, it returns the next instruction and not the current instruction.

Thanks for your support.
