Expected shipping date is end of April (beta interfaces are being tested). The AAI-NIS works with a Satellite ready factory G35 radios. It has two auxiliary inputs selected by the SAT button on face of radio. The G35 Aux input is the first in the industry to use the steering wheel or radio buttons to send out commands to PAC's optional SWI-X which can be used to control an MP3 player, DVD, VCP or most devices that use an infrared remote. The AAI-NIS also comes with a negative remote output when ever in Aux mode. (This aux input will not work if the vehicle is already equipped with a satellite receiver).
