Sounds great, use my iphone now but also enjoy some FM stations and yes I have the apps for them on my phone but i constantly get calls and it ususally occurs when I'm trying to listen to music. Also here in California if I pick up my phone to do something with it I could get pulled over and get a ticket. That would be a reason for me to still have a head unit. The issue with secret audio to me is the wireless remote is ussless to me without the ability to see what i want on my ipod. I want somehting that is 100% wireless display and will display everything form my iphone
