Will an iPhone 5 with iOS 7 work on an Alpine iDA-X305S head unit?

I own an Alpine iDA-X305S head unit which is iPod/iPhone compatible, it allows me to control the music (and Pandora internet radio) from the unit. I'm looking forward to upgrade my iPhone with iOS7, but I would like to know if there's some kind of compatibility issue with the head unit and this new OS. Since the unit doesn't have a CD playback, losing compatibility with the head unit would practically leave me with FM and USB flash drive capabilities in my car.

If I'm running the ios 7 beta 6 version will it brick after it expires for sure? - 1

I got an iPhone 5S today and gave my iPhone 5 to my husband. I was running either iOS 7 beta 5 or 6 on the iPhone 5 and I didn't get a chance to try and get the official version because my husband was in a rush to leave for training. Now he's away in another state for at least a month and won't have access to a computer to try and remove the beta version from his phone. So my question is will his phone deactivate/brick? Is there anything that he can do from his actual phone to try to prevent this from happening? Please help I don't want him to be without a phone for a month and neither of us would know how to fix it if it deactivates.
