RN-42 HID COMBO

Hello there, i am currently trying to develop a combo of joystick and keyboard commands, which would allow me to controll a tablet in my car with ease. Basically making my own navigation system. I am trying to do all this using an arduino leonardo and an RN-42 bluetooth module. I have spent weeks trying to find a code that works and the absolute correct wiring, but nothing i do seems to do anything. I have managed to set my RN-42 as an HID device and change it's name in the comand mode, but that is it. Please, if someone has done this before, can you please point me in the right direction? Thank you.
