Simple no frills way to add BlueToth to older still good radios
This is simple and low cost method to add Bluetooth capability to your older stereo player/car radio/ boat radio / caravan radio / truck radio / tractor radio etc. running on one battery (12V) or two batteries (24V).
Often it is much easier and cheaper, than to replace a still perfectly fine older radio system. Especially if it is a more complex or high quality installation, and you would have to pay a specialist to do the swap.
Another reason is if you do not want the looks of a phone like modern head unit, or do not have the space for it, or simply do not want to be bothered by unwanted and to you useless other features.
Or you simply want to add Bluetooth capability in an invisible hidden away fashion, thereby retaining the original vintage look of your vehicle. Especially if a rare and expensive original vintage radio is involved.
The installation of this Blafili is very simple, I would say right out foolproof.
The product is housed in a partly transparent plastic housing. In bright sunlight you can see through, and it is well made inside. I can recommend it.
Great retro-fit system
This is a great way to add blue-tooth to an existing system without the expensive of a full replacement. It is very easy to install, with clear and colour-coded cabling, reasonably compact unit so easy to find a place to tuck it away, and works great. Pairing is usual routine, sound quality is more than adequate for a car/boat and whole system works great - better than I expected.
Great Product—Follow the Instructions
This product works flawlessly once properly installed. Important tip: the blue wire is REMOTE OUT, not a remote IN. It sends a signal to turn on your amplifier when audio is detected—do not connect it to your radio’s remote lead.
I paired it with my phone and it performs beautifully. Just be sure to read and follow the instructions closely so you understand how the REMOTE OUT wire functions.
1970 Cutlass now in the internet era.
I used this unit to add Bluetooth to my Classic Car Stereo USA-630 in my 1970 Cutlass. I initially used the Classic Car Stereo Bluetooth adapter but after 2 failed units switched to this Blafili unit. The Blafili installation was straight forward and the unit started up in pairing mode without issue. The iPhone found the Blafili immediately and the sound quality was excellent. I highly recommend this unit.

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.
