BLUETOOTH I am having truoble in receiving and making calls with mt bluetooth

If your Nissan Sentra does not come with Bluetooth built-in, you can still add it with an aftermarket Bluetooth receiver. These receivers can be found online or at electronics stores and are relatively inexpensive.
To install the receiver, you can follow these steps:

1. Turn off your car's ignition and open the glove box.
2. Locate the back of the car stereo and find the auxiliary input port. It should be a small, round port labeled "AUX."
3. Connect the Bluetooth receiver to the auxiliary input port with a 3.5mm auxiliary cable.
4. Connect the Bluetooth receiver to a power source, either through a USB port or a 12-volt adapter.
5. Turn on your car's ignition and switch the car stereo to auxiliary mode.
6. Turn on the Bluetooth receiver and pair it with your phone.
7. Once connected, you should be able to play music or take calls through your car stereo using the Bluetooth receiver.

Keep in mind that some aftermarket Bluetooth receivers may have slightly different installation instructions, so be sure to read the manual that comes with your specific receiver.

Go to your Bluetooth settings and forget the device. Then re-pair it for a fresh connection. This worked for me

Try deleting the headset from your phone and then repairing the two again.

Good luck from Headsets Direct!

Turn on your Nuvi, go to Tools in the next screen you should see Bluetooth..... go to Connections and Add Device

Once added make sure Bluetooth says Enable

it make a higher piched bbep when reciving calls. reference wit company

Hello.

From LG Documentation:

To make a handsfree call from the bluetooth device (Voice dialing)
- Briefly press the PWR/END button to activate “Voice Command”.
You will get the best results if you first record the voice dialing tag through
your Headset.

Hope this helps

it's simple,just turn visibility option to shown to all in your bluetooth option,but take care to turn of bluetooth after complition to make safe your mobile from viruses

are you using a bluetooth headset? if yes then check whether u have switched on your bluetooth headset & also your phone & bluetooth headset must be reachable, that is, both should be within range as mentioned in your bluetooth headset manual.  

Wireless device won't work for bluetooth.
You need Bluetooth Transmitter and Receiver.
