your solution helped me! thank you for posting this...
now i just need to figure out a way to keep the digital adapter hidden, and only have the lightning cable exposed.
i also need to find somewhere to mount my iphone.
there are sooo many things to do with the iphone + avic150 that it is going to take me a longgg time to figure it all out! but so far, after only having it for a week, i am thoroughly impressed!
