What this device does

The ESTONE BT70 is a Bluetooth FM transmitter that plugs into a 12-24 V vehicle socket. It streams audio from a paired phone or tablet to the car radio on an unused FM frequency. A 1.7 inch LCD shows the song name, incoming call number and the vehicle battery voltage. Two USB ports provide a 2.4 A smart charge port and a QC 3.0 fast charge port for phones and tablets.

Who it suits and who it does not

Drivers who want wireless music and hands-free calls through an existing FM stereo will find the BT70 simple to set up. The rotating 270-degree gooseneck lets the screen face the driver in most dash layouts. Buyers who need a digital audio output such as optical or HDMI, or who require a built-in DAB+ tuner, should look at a different product because this unit only offers FM and 3.5 mm AUX connections.

Behaviour on long journeys

The BT70 runs from the vehicle electrical system, so it does not rely on an internal battery that could drain over time. CVC noise-cancellation technology keeps call clarity steady during extended drives. The transmitter can be switched off with a long press on the next-track button while the USB charging ports stay active. A TF card slot accepts FAT-formatted cards up to 32 GB for offline playback when a phone is not available.

Questions about this item

What power socket must my vehicle provide for the BT70 to operate?

The unit draws power from a standard 12-24 V car accessory socket, so any vehicle with that voltage range will run it.

Can I still play audio through my car's original 3.5 mm auxiliary jack while using this transmitter?

Yes, the BT70 includes a 3.5 mm AUX input and output, letting you route sound through the factory aux port alongside the FM signal.

How do I confirm the transmitter is broadcasting on the correct FM frequency after I plug it in?

The 1.7 inch LCD backlight display shows the active FM channel, song title or caller ID, and the car battery voltage at startup.
