You're correct about using the cable instead of BT streaming. There are many advantages this way. I don't think the iOS7 will add anything to the voice commands. I'll wait to see the video, hopefully I'll see something there.

I just installed ios7 to test it and I'm hoping that i don't have any additional issues. I have not been in the truck yet to see.
I'll try and do a video if I can of the quirkiness.
