I have a 2008 G35X with navigation. My Iphone connected both in bluetooth
and with that cable from the arm rest console.

My question is how to interface my new Samsung Galaxy S3 smartphone. It paired
without issue via bluetooth. I want to play music and wondered if it can be
done via a bluetooth connection or is there a cable available to connect to
the S3?

The Samsung S3 uses a mini USB connector. So I would imagine there is
a cable with that DIN looking connector terminating in a mini USB.

Anyone integrated an S3 yet??

 

best bet is just the aux input sorry, iphone have car integreations android does not....

 

Would be nice if we have a usb port

 

even if you did have a usb port, most likely you wont be able to interface your android phone, i thought that the new infinitis got bluetooh streaming, but i may be wrong.

 

Via OEM, your only option is to play music through the RCA jacks in the armrest.
The bluetooth in your G is only going to work for the phone function. A2DP (to BT stream music) was added to the G in the 2010 model, as well as a USB port
There are after market BT devices that will connect to your RCA and pair with your phone but to be honest, it's probably not worth it. It will sound better using RCA cable.

 

You can buy a bluetooth module and hook it up to your RCA jacks for streaming media from your phone. It won't be seamless and the buttons on your car won't be able to do anything other than turn up the volume.
