Bluetooth 5.0 FM Transmitter

The Audiovox T25 plugs into a cigarette lighter and streams audio from a smartphone to a car stereo over an FM frequency. It also plays files directly from USB flash drives or microSD cards up to 32 GB each, supporting WMA, MP3, WAV, APE and FLAC formats.

Dual USB charging and voltage display

Two USB-A ports deliver 5 V at 2.4 A and 5 V at 1 A simultaneously with over-current, over-voltage, short-circuit and temperature protection. The unit shows the vehicle battery voltage on its screen when powered, while a blue backlight ring aids visibility in low light.

CVC noise suppression for calls

Built-in CVC technology reduces background noise and echo during hands-free calls and voice navigation prompts. Buyers who need an auxiliary-in cable, fast-charging protocols such as Quick Charge or Power Delivery, or a Bluetooth version newer than 5.0 will not find those features here.

Questions about this item

How do I install the T25 FM transmitter and which step do people often miss?

Plug the T25 into the 12 V cigarette lighter socket, pair your phone via Bluetooth 5.0, then tune the car radio to the same empty FM frequency shown on the transmitter display; the step many skip is matching that exact frequency on the radio before playing audio.

What maintenance or replacement will the T25 need over time?

The T25 has no user-serviceable parts; keep the 14.33 in × 12.83 in × 9.06 in housing free of dust, check the blue ambient light ring for dimming, and replace the unit if the Bluetooth 5.0 link or dual USB ports (5 V 2.4 A and 5 V 1 A) stop working.

What limit appears first during long drives with the T25 running continuously?

The 0.059 kg transmitter relies on passive cooling, so sustained dual-USB charging at 2.4 A and 1 A plus Bluetooth 5.0 streaming will hit its thermal protection circuit first, causing the blue light to dim and output to throttle until the unit cools.
