I have a 2006 Infiniti G35 Coupe and I would like to connect my iPhone to the factory installed radio. I have looked at several options such as the iSimple Gateway ISNI571 and the Audiovox MediaBridge 1503NIS and they both seem to be compatible but before I purchase one of them I wanted to see if anyone has had any experience using either of these devices in a similar circumstance. Any input would be very helpful.

Thank you!
