I have a 2011–2012 Infiniti G25x with the non-Bose, non-navigation factory stereo. The car already has Bluetooth, but there was an important limitation: the factory Bluetooth was mainly for phone calls, not for streaming music from my phone.
That was fine when I only needed Bluetooth for calls, but music was a different story. I use my phone for most of the music I listen to now, so I wanted a way to connect it to the factory stereo without replacing the original radio.
The interesting thing about my G25x is that there is already an iPod/iPhone USB input inside the center console. I realized that this could be more useful than I originally thought if I could find a way to make my phone work through that connection.
That's what led me to the GITANK Bluetooth Adapter. Instead of replacing the factory stereo or adding Bluetooth directly to another part of the car, the adapter works through the existing iPod USB port. In simple terms, it allows my phone to work more like an iPod through the factory system.
Once I connected it and paired my phone, I could start streaming music through the factory stereo. What surprised me was that it wasn't simply a basic Bluetooth audio connection. The factory system could also display information such as the artist and song title.
I can also use the steering wheel controls to control the music, including skipping to another song or going back to the beginning of the current track. Having those controls still work makes the whole thing feel much more integrated with the factory system.
I also tested it with several phones I had available, including my Samsung S24 Ultra, S22, Note10+, S7, and even my old S4. They could all work with it. I also tried different apps, including Spotify, Digitally Imported, and Shazam, and they all worked well for me.
As for the sound quality, I've been very satisfied with it. The sound is rich and full, and it works well with my Infiniti's audio setup. I also pay attention to the quality of the music files and streaming settings I use. If the source itself is heavily compressed, I don't think it makes much sense to expect the adapter to somehow restore that lost quality.
My own G25x audio system has also been upgraded with additional equipment, including a Boston Acoustic 10-inch subwoofer and Boston tweeters, so I have a pretty good idea of what my system sounds like. After adding the Bluetooth adapter, I finally had a convenient way to stream music from my phone without giving up the factory stereo.
What I like most about this solution is how much it uses what was already in the car. The iPod USB input was already there, and instead of leaving it behind as an outdated connection, this adapter gives it another use with a modern smartphone.
I also looked at other ways of adding Bluetooth, but compared with soldering a Bluetooth adapter into the Satellite box in the trunk, using the existing USB connection was much simpler for me.
After using it, I'm very happy with the result. My G25x is an older car, but I don't feel like I need to replace the factory stereo just to make it work better with the phone I use today. With the Bluetooth adapter now I can keep the original system, see the song information on the display, use the steering wheel controls, and stream music from the apps I already use.
For anyone with a similar non-Bose, non-navigation Infiniti setup who has been looking for a way to add Bluetooth music, I think this is worth considering. For me, it was a much simpler solution than replacing the factory stereo or making a complicated modification.
