I drive an Acura TL that comes with a feature that allows me to pair my iPhone to the cars navigation system and use a handsfree system. I've been driving Acuras with this same feature since the first iPhone came out. The problem that I am having seems to be limited only to the iPhone 5 and I'm not sure if the problem is with my phone or the newer model car that I am driving. Basically, I went to pair my phone and everything was fine but I noticed that all my facebook contacts also synced. This is new behavior. My iPhone 4 synced to this same car last week with no facebook contacts. I am thinking my problem resides in the newer facebook integration with the iPhone 5. Is there any way to completely disable this feature? I really don't need all those contacts in my contacts either on my phone or in my car. I went under settings=>facebook and turned facebook off, but that didn't work. I also tried deleting the facebook app from the phone altogether. No luck there either. I notice now in the Contacts app, there is a Groups menu. This is new, right. I unchecked facebook and still no luck. I am at a loss. Sure, this may be a first world problem, but it sure is annoying. If anybody who has an iPhone 5 and drives a 2012 or newer Acura can provide any insight into this, I would sure appreciate it. Or if there is some way to disable the facebook integration, that'd be cool too.
