Mitsubishi RVR 2014 GT Takes a long time to connect to iPhone 4S
 

Hi,
Everytime I plug my iPhone 4S into my USB cable that connects to my audio deck, the thing takes a while to connect to the audio deck (about 5 minutes or so). I would expect this would be instant. I want to be able to also play any music from the iphone and have it stream through the audio system. The audio system currently tries to use iTunes on the iphone only (podcasts, siri etc. dont really work). Has anyone noticed this? why is the audio operating system suck so hard?
Thoughts?
Thx
