I know this is a issue that keeps coming up, but i just want to make sure it works before i upgrade to the iphone 5s. I have a avic-z140bh and haven't done a upgrades or anything to my system. But I am going to get the new iphone 5s and want to make sure that the upgrade or download that they have will work with my phone. Anyone please help. Thanks

Just upgraded mine. Overall no issues. See my post of today.

Can you tell me which download to use? So far I haven't done any downloads to my system at all. I want to make sure i do the correct one. Thanks.
