Common questions about the GizmoVine GV-FMT-42B
The questions buyers ask most before fitting a Bluetooth FM transmitter to a car that has none.
Will it work if my car has no Bluetooth at all?
Yes — that is exactly what it is for. The transmitter plugs into the 12 V socket and sends the audio to your existing car radio over FM. Your phone pairs with the transmitter rather than with the car, so no factory Bluetooth, no adaptor loom and no trip to a workshop are needed.
How do I pick an FM frequency?
Any free frequency between 87.5 and 108.0 MHz. Tune the transmitter and the car radio to the same one and leave some distance from strong local stations. A quick scan on the radio will show you which parts of the band are empty where you drive.
Can I charge a phone and play music at the same time?
Yes. Charging runs independently of the audio link, so the USB ports stay free for a phone or tablet while music is playing.
Does it handle hands-free calls?
Yes. A built-in microphone routes calls through the car speakers, and CVC noise reduction filters out background noise.
Will the sound match a wired connection?
It is close, but not identical. Quality depends mainly on how clear the frequency you choose is — picking an empty part of the band is the single biggest improvement you can make.
