You can talk to your JVC receiver using Amazon Alexa. With the built-in Alexa, you can play music, make calls, listen to audiobooks, hear the news, check the weather, control smart home devices, get directions, find parking, and much more—all while keeping your hands on the wheel and your eyes on the road. You can connect two phones all day long via Bluetooth with secure and easy pairing. Calls to either of the two phones can be answered with the push of a button on the main unit. Low battery information: When the battery of the connected Bluetooth device is nearly empty, a beep will sound, and "Low Battery" will be displayed on the receiver.
