Scosche C89S Bluetooth 5.4 Car Adapter 48W

Scosche C89S Bluetooth 5.4 Adapter

The Scosche C89S adds wireless audio and fast charging to vehicles lacking built-in Bluetooth. It plugs into a 12V or 24V cigarette lighter socket and transmits sound to the car radio via FM frequencies. The unit supports Bluetooth 5.4 for streaming from smartphones, USB drives or TF cards up to 64GB. It delivers 48W total output through PD and QC 3.0 ports to power three devices at once.

Drivers upgrading older cars 1990-2020

This adapter suits owners of older vehicles without AUX ports or factory Bluetooth who want hands-free calls and app audio through the existing stereo. It works in cars, SUVs, trucks, motorcycles, RVs and vans. Buyers needing a permanent integrated head unit or digital audio outputs such as optical or HDMI should look at a different product category. The device relies on FM transmission, so users in dense urban areas with crowded radio bands may experience interference.

Check 12V or 24V socket and FM space

Before ordering, confirm the vehicle provides a standard 12V or 24V cigarette lighter outlet for power. Ensure at least one clear FM frequency exists locally — 88.1, 88.3 or 106.9 are common examples — so the transmitter can be tuned without static. Verify your phone or media player supports Bluetooth 5.4 pairing for the wireless link. The adapter measures 2.12 x 1.8 x 3.3 inches and weighs .059 kilograms, so check physical clearance around the socket.
