## Summary description

Car FM transmitter Retoo E089 connects via Bluetooth to stream audio from phones and devices and transmits it to a vehicle radio. Features MP3 playback from SD card, dual USB ports for charging, and an LCD for frequency and track info. Ideal for hands-free calls, music playback and charging devices when a car lacks modern infotainment.

## Long description

The Retoo E089 FM transmitter provides a simple way to add Bluetooth audio streaming, MP3 playback and device charging to vehicles without modern infotainment systems. It pairs with phones and other Bluetooth sources to send music and hands-free calls to the car radio via an adjustable FM frequency. The unit also supports MP3 files from an SD card, shows frequency and track information on an integrated LCD, and offers two USB ports for charging mobile devices simultaneously.
Advantages
The Retoo E089 combines wireless streaming and wired media playback in a compact plug-in module. Bluetooth connectivity enables hands-free calling and wireless audio streaming while the SD card slot allows direct MP3 playback without a phone. The dual USB charger supplies power to two devices at once, and the LCD provides clear indication of the selected FM frequency and basic track information. Installation requires only a vehicle 12V socket and an FM radio, making it a portable and user-friendly solution.
Suitable for
 Drivers who want Bluetooth audio and hands-free calling in older cars
 Users who play MP3 files from SD cards without relying on a mobile device
 People needing to charge two USB devices simultaneously while driving
 Situations where a simple plug-and-play audio upgrade is preferred over replacing the head unit
When it may not be suitable
The Retoo E089 requires a functioning car radio with adjustable FM frequency; in vehicles with only digital or non-FM audio inputs it will not provide audio output. Performance can be affected by FM signal interference in areas with crowded radio bands, which may cause occasional noise or reduced audio quality compared with direct wired connections or modern Bluetooth-enabled head units.

How to use
Plug the Retoo E089 into the vehicle 12V socket and power it on. Pair your phone or other Bluetooth source with the transmitter following the device pairing procedure shown on the phone. Tune the car radio to an unused FM frequency and set the same frequency on the transmitter using the LCD controls. For MP3 playback, insert an SD card containing compatible MP3 files and use the transmitter controls to navigate tracks. Connect devices to the USB ports to charge while driving. For hands-free calls, accept or end calls from the phone or the transmitter controls, and speak normally toward the vehicle cabin where the microphone can pick up voice.
What to consider before purchase
 Confirm your vehicle has a standard FM radio and a 12V power socket for the transmitter
 Expect audio quality to depend on local FM band congestion and signal interference
 Check SD card compatibility and format MP3 files properly for playback
 Ensure the dual USB output meets the charging requirements of your devices
Usage recommendations
For best audio quality, choose an FM frequency with minimal local radio stations and position the transmitter to avoid obstruction by other devices. Keep the phone and transmitter firmware or Bluetooth profiles up to date for reliable pairing. Use a high-quality SD card formatted to standard FAT/FAT32 and limit the number of nested folders to ensure smooth MP3 playback.
