Yes, the CoolStream CarPro for BMW will work with the Infiniti 2008 G37. It is necessary, however, to use an additional 30-pin Charge Converter Adapter along with the CarPro.
This adapter needs to be connected to both the 30 pin connector and the Infiniti 2008 lighter socket by a micro USB cable. The CoolStream CarPro then goes on top of the adapter. Using the CarPro and charge converter together, you will be able to stream music from any iPhone or Android phone to the Infiniti 2008 G37 speakers.
The CarPro works with the music controls on the steering wheel of the Infiniti. The CarPro will also display the music that you have downloaded and saved on your iPhone.
CoolStream can also confirm that the following models from Infiniti will also need this additional adapter.
EX-35 2008 and 2009
G-37 and G-37X 2008
How to know if you need an adapter?
If the factory-installed iPod cable in your Infiniti will NOT charge an iPod, iPhone 3, or iPhone 4, then you will need this adapter.
