Monster FM Bluetooth Transmitter - $7 (Moscow)

A bluetooth transmitter to stream music/calls from a phone, USB, or microSD into old car radios, with 2 USB phone chargers.
Also supports siri and google virtual assistant for operating the phone hand-free.
Like new, comes with original box and instructions.
Selling it because I changed my truck's radio and the new one has bluetooth and integrated USB chargers.
This transmitter works by connecting to your phone via bluetooth, from which it receives the audio signal, and it emits the audio on a radio frequency of choice, to which you tune your car's radio.
Very easy to set up.
It is powered through the car's cigar lighter just like any normal car phone charger.
Originally bought new at walmart for ~ $15, selling for $7.
