How many points before your license is suspended in TN?

I just purchased a Honda Ridgeline and it’s truly an awesome truck. One of the things that sold me was that it had some more upscale infotainment features than you’d find in other similarly sized trucks. The only problem is that the previous owner’s Bluetooth devices are in the infotainment system—how do I delete them so I can add my own?

What’s the best way to calculate the monthly interest on my car loan? I want to make sure that I’m budgeting enough for all of my payments.

I was looking at car loans and most of them say you need to show proof of income. I've only had my current job for three months. Before that, I had a long period of unemployment. How many months of income do you need to buy a car?
