iOS 6 Bluetooth Handsfree Contacts showing Facebook Contacts

I have upgraded to iOS6 and am loving all of the changes.I am having issued with my VW Bluetooth hands free kit in my car and my contacts. I have set up Facebook contacts sync in iOS6 so that facebook information if added to my existing contacts and the pictures are downloaded and updated GREAT!

I like to keep my phone contacts and my Facebook contacts seperate so I have selected the option in Phonebook so that only my iCloud contacts are displayed rather than both iCloud and other Facebook contacts, again this works great.

The problem starts when I search my phonebook over Bluetooth with my car hands free, all of the Facebook contacts are included in the phonebook which is not what I want. I only want my iCloud contacts to be shown as anyone I would even need to ring would be in my iCloud phonebook.

Is there a way, apart from disabling facebook contact sync, to have only my iCloud contacts sent over bluetooth to my hands free?

It would be great if there was a setting that could be turned on so that all facebook contacts are hidden apart from ones linked to existing iCloud contacts.

Hope this makes sense.

Thanks
