We received this yesterday and love it! Sounds great through the speakers. We purchased the newest model for a little extra. Glad we did.
Plug it into your cigarette lighter, (bluetooth is already on when you plug it in), turn your phones Bluetooth on, pair devices, switch to FM channel listed on display (107.9), play your favorite music apps. (Amazon, Apple, Pandora, etc..)
As long as your phones bluetooth is turned on and the device is plugged in, there is no need to pair devices again. When you start the car up it will automatically say "Pairing" and connect automatically.
You can switch songs from the unit, adjust volume and make calls which will come through your speakers for hands free talking.
I am purchasing another one today for another older vehicle we have. Very happy with our purchase.
