What is a Bluetooth Connectivity?
Pairing your phone wirelessly.
Simplified animation — not to scale.
In plain English
A short-range wireless link between your phone and the car, used for hands-free calls, streaming music and transferring your contacts list.
A simple analogy
"It's the car saying "hi" to your phone over a private little radio channel — no cables, no internet needed."
How it works
Both devices broadcast a low-power radio signal in the 2.4 GHz band. When you put the car into pairing mode and select it on your phone, they swap security keys once — after that, they reconnect automatically every time you get in.
