CRUST CS45 Car Bluetooth FM Transmitter with Call Receiver
Overview
The call receiver side matters most for daily driving: the built-in mic takes calls through the system, which is also the legal way to talk while driving. USB ports charge phones simultaneously, and music streams from any phone over Bluetooth or a pendrive.
Audio quality is FM-broadcast quality - good, not audiophile. The candid alternative for newer cars is AUX or built-in Bluetooth. But for the millions of cars on Indian roads without either, this is the upgrade that fits in the cupholder.

Buying Advice
Product Description
The FM transmitter concept is elegantly simple: the device receives audio from your phone, then re-broadcasts it on an empty FM frequency that the car radio tunes into. No wiring, no installation, no head-unit replacement - the car's existing speakers do the work.
- Bluetooth-to-FM bridge - pair the phone once; every subsequent drive auto-connects. Spotify, YouTube, podcasts and calls all route through the car system.
- Built-in call microphone - incoming calls answer through the transmitter; the conversation plays through the car speakers. Hands-free legality with the factory radio.
- USB charging ports - phones charge while playing; the 12V socket's single slot becomes a hub.
- Pendrive playback - load a USB stick with music and the transmitter plays it directly - the no-smartphone option for shared family cars.
Setup discipline that makes it work well: find an empty FM frequency in your city (the lower bands are usually quieter), save it to both radio and transmitter, and the pairing stays stable. Frequency interference in dense city centres is the category's known quirk - re-tuning occasionally is normal.
The honest audio ceiling: FM broadcast limits quality to good-radio standards - comfortably better than the 2010-era head units it upgrades, below wired AUX fidelity. For calls and daily music, the gap does not matter.
At Rs 949 with the CRUST build quality, this is the gift every car-owning parent secretly needs and never researches: their existing car, suddenly connected.
