Universal car audio adapter

The Jansicotek BT70 plugs into any 12 to 24 volt socket and streams audio from a phone or TF card to the vehicle FM radio. A 270 degree gooseneck lets the 1.7 inch LCD face the driver for song titles, caller ID or battery voltage. Two USB ports charge a phone and a tablet simultaneously.

Thermals noise and power draw

The unit draws power directly from the lighter socket and runs cool during normal operation with no fan or audible noise. Bluetooth 4.2 with EDR maintains a stable link while consuming minimal energy. The QC3.0 port negotiates 3.5 to 12 volts at up to 3 amps without overheating the adapter.

Bundled accessories and software

A 3.5 mm audio cable is included for a wired AUX connection when FM reception is weak. The LCD backlight shows incoming call numbers and battery status automatically. TF cards up to 32 gigabytes in FAT format play MP3 or WMA files without a phone. CVC noise cancellation sharpens hands free calls.

Questions about this item

How do I install the BT70 and what step is often missed?

Plug the unit into the 12-24 V accessory socket, then rotate the 270-degree gooseneck so the 1.7 inch LCD faces you; the step people skip is tuning the car radio to the exact FM frequency shown on the display before pairing.

What maintenance or replacement will the BT70 need later?

The TF card slot supports FAT-formatted micro SD cards up to 32G; if the card fails or you want more music, replace the card — no other user-serviceable parts are inside.

What limit appears first during a long drive with both USB ports in use?

The QC3.0 port steps down from 3 A at 3.5-6.5 V to 1.5 A at 9-12 V, so sustained fast charging at higher voltages will hit the 1.5 A ceiling first.
