Works great in a boat with moisture.

I love this thing. I installed it on the Pyle Amp we had in the Yamaha jet boat. The radio didn’t work when we bought it. Only way to control the volume is with the phone which 9/10 times is no issue. Haha

Amazing sound, quick-start, and LOUD output system for classic cars. Pair this with any Amplifier.

I have a 1960's car overseas and this will be going in next month. This is a super-simple "hide away" adapter that allows an older car to have superb quality APTX-HD audio from your modern device. Keep your car stock! This can be paired with any modern amplifer and a modern speaker while leaving that classic radio intact.

This has been designed with some thought rather than "down to a price" and it shows.

This starts-up with no annoying sounds, and it just boots and connects all automatically in seconds. The audio is clean, punchy and the line-level output is LOUD at full volume, with all adjustments being done on the BT device.

Supports the old SBC, CSR/Qualcomm APTX and the excellent APTX-HD. For iDevices, you'll use AAC but Apple doa great job there with encoding.

Installing is "DIY" simple. The casing is sealed and the cables are secured very well. Find an area that's out of sight, but still has some clearance for the inbuilt-antenna. Two solid screw tabs are provided to screw to the car, or you can cable-tie to this something else as there is ample openings in the slots. Connect to power and ACC and the unit will simply start-up. To output audio, there are two small flyleads with RCA plugs to plug into a suitable amplifier.

"bench testing" it was flawless. It worked right throughout the house without a disconnection. Audio was clean and clear and thanks to APTX, it had plenty of punch through the attached HTS.

Perfect Product

This is a great product and a good way to get High Definition audio over bluetooth in your vehicle. My truck has old non hifi bluetooth and I thought it could sound better well it can. This device provides a much cleaner connection from my phone to my audio system and sounds great.

Before you ask.

How to add Bluetooth to an old car stereo?

Wire the CAR receiver to the head unit's RCA (aux) input and a 12V-24V switched power line; pair your phone once and it reconnects on every drive.

What's the best 12V bluetooth receiver?

For hardwired installs, the blafili CAR covers 12V-24V systems with dual RCA output, hands-free calling and BT 5.2.

Does the blue remote trigger wire keep my amplifier on whenever the vehicle key is on?

No. The blue remote trigger wire is audio-activated, not ACC-switched. It outputs power only while Bluetooth audio is actively playing. This helps turn on your amplifier only when needed during music playback. If you want your amplifier to stay on continuously whenever the key is on, the amp remote wire should be connected to the vehicle’s ACC or ignition-switched circuit instead.

Why doesn’t my amp stay on for navigation prompts when no music is playing?

The blue remote trigger wire turns on only when Bluetooth audio is actively playing. In navigation-only use, short spoken prompts may not keep the amplifier awake the same way continuous music playback does. If you need the amplifier to remain on whenever the vehicle is on, use the vehicle’s ACC-switched remote circuit rather than relying on the audio-triggered blue wire.

I connected yellow to 12V and black to ground but nothing happens.

Please connect the ACC wire to switched 12V (ignition). Yellow+Black alone won’t turn it on.
