I got my dealership (after half an hour of convincing them it existed) to update my Intellilink and am using it with iOS7 on an iPhone 5, hasn't been any problems so far with Siri, I use it for q a lot now since the update (although have had to take the pincode lock off the phone as it won't work if it's locked with this security, which is a bit of a dodgy compromise I realise)
