iPhone ios 5 still won't send vCard contacts via bluetooth to car system

I have an iPhone 3GS and am running iOS 5.0.1. I have a 2011 Toyota Camry with built-in bluetooth. I see a lot of posts from people talking about the fact that the iPhone can't send vCard name/phone number contact information to a car bluetooth system. Sending via MMS or e-mail is not an option to a car system like this. The car bluetooth system gets put into a mode where it waits for the information from the phone. But there is no option in iOS to send vCards via bluetooth. This capability is something my wife's free Samsung Solstice phone can do, but my "smartphone" / iPhone cannot. Every number I call from the iPhone, therefore, shows as calling "no name" as I can't get basic contact names/numbers sent to the car's system. This is not a far fetched feature and many phones (free ones at that) can do this. When will users be able to get this basic feature? All I need is send vCard contacts via bluetooth...As I said, sending via MMS or e-mail doesn't work for a car. I shouldn't need some app to do this either. It should be another transport feature on the vCard export from iOS.

Thanks,

Michael
