Nulaxy KM19
The car running:
1) Find a vacant radio frequency
2) Plug it into your cigarette lighter, it will turn on automatically and sync your device to the radio frequency that you chose. This you do by pushing the CH+ or CH- button on your KM20. After choosing the frequency it will take a few seconds to get in sync.
3) Sync your phone to the device by pressing the phone button and make sure that you go to your Settings and look under Bluetooth and then look for KM20. That will take a few seconds to sync. YOU'RE DONE.
Now you can get your phone calls, make calls, listen to your music from the phone or listens to books from your phone. It doe take longer to read this than to set it up. What I love about it, it is wireless. You don't need to get a new radio, keep the original stereo for the car. And it does not take any space whatsoever. THE ONLY THING THE MANUFACTURE SUGGEST IS TO UNPLUG IT BEFORE STARTING THE VEHICLE.
