Car Bluetooth hands-free transmitter with FM transmitter and MP3 player functionality featuring USB charger port and TF card slot in black for wireless audio streaming and hands-free phone calls
G7 Bluetooth Car Hands-Free Transmitter with FM Transmission, MP3 Playback and USB Charging

The G7 Bluetooth car hands-free transmitter consolidates multiple car audio functions into one compact device that plugs directly into your vehicle's 12V power socket. This unit serves as an FM transmitter, Bluetooth audio adapter, MP3/WMA player, and USB charger, designed to upgrade older car stereos without Bluetooth capability or auxiliary inputs. By transmitting audio wirelessly via FM radio frequency, it allows you to stream music from smartphones or play files from USB drives while maintaining safe, hands-free phone call functionality through automatic call/music switching.
Features and Construction

The G7 employs specific technical components to deliver its advertised functionality, focusing on practical audio transmission rather than unnecessary features.
Material and Build
This device incorporates a professional high-performance Bluetooth module that manages wireless audio streaming between compatible phones and the transmitter. The built-in MP3/WMA decoding chip processes digital music files from connected storage devices, converting them for FM transmission. The housing is finished in black, though the exact plastic polymer composition isn't detailed in the source material.
Size and Practical Fit
The G7 is designed to occupy a single 12V power socket (commonly called a cigarette lighter socket) in your vehicle's dashboard or centre console. Its compact form factor means it doesn't obstruct other controls or storage areas when installed. The integrated USB charging port provides 5V power output for charging mobile devices while the transmitter operates, though exact amperage specifications aren't provided.
Uses and Placement

This device addresses specific scenarios where drivers need to integrate modern audio sources with older car audio systems while maintaining driving safety.
Event or Professional Use
For drivers who frequently make business calls while travelling, the automatic switching between music playback and hands-free call mode allows professional conversations without fumbling with phones. The ability to play presentation audio or training materials from USB drives via the car stereo makes it suitable for mobile professionals who need to review audio content during transit between appointments or meetings.
Everyday Home Use
For daily commuting and family travel, the G7 enables safe listening to streaming music services, podcasts, or audiobooks from smartphones without requiring expensive stereo upgrades. Parents can keep phones securely stowed while still accessing children's entertainment audio during long journeys. The hands-free call functionality meets legal requirements for phone use while driving in many regions.
Benefits and Buying Value

The G7 offers practical advantages through function consolidation and compatibility with existing vehicle equipment.
Reuse and Low Maintenance
As a plug-in device rather than a permanent installation, the G7 can be transferred between vehicles or removed when not needed, unlike built-in Bluetooth systems. There are no complex wiring installations or professional fitting requirements—simply plug into any standard 12V socket. The absence of moving parts in the audio transmission system reduces potential maintenance issues compared to mechanical CD players or tape decks.
Why Choose This Product
The G7 provides a cost-effective alternative to complete car stereo replacement for adding Bluetooth functionality. Its multiple integrated functions—FM transmission, MP3 playback, USB charging—eliminate the need for separate devices cluttering the dashboard. The professional-grade Bluetooth module offers more reliable connectivity than basic budget transmitters, while the automatic call/music switching enhances convenience during driving.
