My phone is Bluetooth connected in my car and I just press a button on the steering wheel and give a voice command. Likewise if someone rings me, just press a button and talk, that's the only safe way to use the phone in the car.
Recent studies show hand-free phones are about as dangerous as drink-driving.
generally when it comes to anything with motorcycles it is a small community, try and get people to spread the word, example stuff for free? make videos? Market it i suppose, what would make someone go to your store instead of the one next door or why not go online...
