Ive basically read through almost all the bluetooth threads on the forums and there are always mixed answers about whether a specific bluetooth receiver works for their car and phone or not. So I will make it as simple as i can to find the best option becausw i bought a couple of the receivers people suggested but they dont work.
I have a 2008 G37S coupe with navigation and a samsung note 4.
I want to be able to bluetooth music and auto connect when i enter the vehicle. And being able to use the steering wheel to change tracks would be awesome. Also seeing song info on screen would be a plus.

I have rca not usb connections in the center and an ipod dock.

Can somebody give me the best options for using one of the two? And what other accessories need to come with the item if i need any?
I saw the homespot nfc receiver but idk how it performs. I would LOVE to be able to see tracks on screen and use steering wheel functions though...

Sidenote: any information on 2010 and up models are pretty much irrelevant to this because there are different functions and ports compared to my 2008 correct?

 

I literally have the exact same setup down to the note 4.

I bought the Tune2air wma1000 for about $89 from Amazon. You'll need the factory iPod cable for Infiniti. No track info unless you're note4 is routed and you use an AirTunes emulator. If combined with iPhone you'll get track info.

I play Spotify on my note4 and it plays through the iPod interface, no wires required, no pulling the phone out of my pocket. Also keeps steering wheel controls.

Let me know if you need more details. I'm typing from my phone so I'm out.
