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.
