If you own a 2010–2013 Infiniti G37, you may have noticed that Bluetooth works for phone calls, but music streaming isn’t available. So how can you play music from your phone through the car’s stereo?
The factory head unit in most G37s only supports HFP (Hands-Free Profile) for calls. Streaming music, which uses A2DP, isn’t built in. The good news is you can add it without changing the dashboard or losing the original look. With the right adapter, you can stream music from popular apps like Spotify, Pandora, Apple Music, or YouTube Music.
Most G37s were designed so that Bluetooth handles phone calls, while music playback is done through USB/iPod, AUX, or RCA connections. If you check inside the armrest, you might see a USB port ,RCA or a 3.5mm AUX input. These are the main ways to bring Bluetooth music into your car.
Have you ever wondered why USB usually sounds better than AUX? USB sends a digital signal, while AUX is analog, which can slightly reduce audio quality.
A USB Bluetooth adapter plugs into your G37’s factory USB port. The car treats it like an iPod, allowing your phone to stream music wirelessly.
Benefits:
Plays music through the factory stereo
Steering wheel buttons control tracks
Song titles appear on the display
Supports apps like Spotify, Pandora, Apple Music, YouTube Music
Phone calls continue to work as usual
It’s neat and keeps your interior stock.
If you're ready to enhance your driving experience, check out this USB Bluetooth Adapter. It’s easy to install and works seamlessly with your G37’s existing system.
If your G37 has a 3.5mm AUX input, a Bluetooth-to-AUX adapter is a quick solution. Pair your phone and select AUX on the head unit.
Things to know:
Works with all major music apps
Steering wheel controls won’t work
No song info on the display
Slightly lower sound quality than USB
It’s convenient for a simple setup.
RCA adapters connect to the car’s analog stereo input. They’re useful if you have an aftermarket amp or want a more stable analog connection than AUX.
Pros: Cleaner analog signal, works with aftermarket amps, compatible with popular music apps
Cons: No steering wheel control, requires a small adapter, installation slightly more involved
For full modern features like Apple CarPlay or Android Auto, an aftermarket head unit is an option. Keep in mind:
Dash kits and wiring adapters are needed
Steering wheel controls may require a separate module
Bose-equipped cars can complicate installation
OEM interior look may change
This option is best if you want a fully modern interface and full music app support.
Will Bluetooth music interfere with phone calls?
No. Calls and music operate separately on the factory system.
Do navigation prompts still play over the car speakers?
Yes. Phones mix navigation audio with music, so directions come through clearly.
Does this support Spotify, Pandora, Apple Music, and YouTube Music?
Yes. USB, AUX, and RCA adapters all allow streaming from these apps. USB provides the best experience with song info and steering wheel controls.
Is USB sound better than AUX or RCA?
Generally, yes. USB sends digital audio directly. RCA is better than AUX for analog setups but doesn’t carry song info.
Does every G37 have a USB port?
Not all trims. Check the center console or armrest. Some trims only have AUX or RCA-ready inputs.
Can I use RCA if I have an aftermarket amp?
Yes. RCA is often the cleanest analog connection for amps and more stable than AUX.
