I own a 2013 Infiniti G37 without navigation. When I bought the car, I was happy with the factory audio system, and I didn't have any reason to replace it. The radio has a USB input and Bluetooth for hands-free phone calls, so it covered the basic things I needed.
The problem was music. The factory system could handle phone calls over Bluetooth, but it didn't support Bluetooth music streaming. As I started using my phone more for music, I wanted an easier way to play that audio through the car's speakers. At the same time, I didn't want to replace the original radio just to add one feature.
That turned out to be harder to solve than I expected. I spent quite a while looking for a compatible adapter, and like many other owners, I found that not every Bluetooth product is designed to work with an older factory audio system.
What I was looking for was pretty simple: something I could plug into the existing USB input, pair with my phone, and use without changing the original setup.
Eventually, I found this Gitank bluetooth adapter and decided to give it a try.
The setup was straightforward. I plugged the adapter into the USB port and paired it with my phone. Once connected, I could stream audio through the factory speakers without having to replace or modify the original radio.
That was probably the biggest reason I liked the setup. I wasn't looking to completely change the way my G37 worked. I just wanted to add a more convenient way to listen to music, and this allowed me to do that while keeping the factory system.
After using it, I also noticed that it worked with some of the features I was already used to. The factory display can show the artist name and song title, and I can use the steering wheel controls to control the music.
Those details make the experience feel much more natural. I don't have to reach for my phone every time I want to change a song, and I can continue using the controls that are already part of the car.
Another thing that mattered to me was the built-in hands-free calling. Since the G37 already has Bluetooth for phone calls, I wanted to keep using that feature instead of replacing it with something else.
The adapter works alongside the car's existing hands-free calling, so I can use Bluetooth for music while keeping the original phone function. That makes more sense to me than replacing the whole system just to get Bluetooth audio.
So far, the audio experience has been good. I haven't experienced the delays or audio cutouts that I have seen with some other Bluetooth products. The music has played consistently, which is something I care about when listening on the road.
Of course, there is one small thing that could be improved. When I switch to a different audio source, the adapter doesn't automatically pause the music that is streaming. It's a minor inconvenience, but it doesn't really affect me because I rarely listen to the radio anyway. I don't switch between audio sources very often, so it hasn't been a problem in my normal use.
Looking at the whole experience, I'm happy that I found a way to add Bluetooth music without replacing the factory stereo. My G37 is an older car, but I don't feel like I need to change the entire audio system just to make it work better with my phone.
For me, the best part is simply being able to keep the original setup while making it more convenient to use with the phone I already have. After looking for a compatible solution for so long, it's nice to finally have one that works well for my needs.
If you have a 2013 Infiniti G37 with a similar factory setup and you're looking for a way to add Bluetooth music without replacing the original stereo, this is one option you may want to consider.
