I know the tune is vital. I just need to find someone to do it. I actually am in SC right now but I'm moving to NY this saturday so I dont know anyone in NY. If someone told me a way to find someone who knows how to tune in NY I'd gladly pay. And I will be monitoring for knock. I'm ordering this to allow me to see everything on my phone. Seems like a nifty little device
