iOS and 2011 Hyundai Sonata Phonebook

I have a iPhone 4 running 5.1.1, i also have a 2011 sonata w/ nav package. I notice no matter how i have the contacts sorted on my iPhone, they always appear on the car's phonebook with LAST NAME, FIRST NAME. This is kinda annoying, because if you want to use the voice command to call someone, you have to say their name in that order. I was just wondering if anyone has the same car and has experienced this and possibly a fix. I am not sure, but I'm thinking it might be a limitation on the car, not the phone. I apologize in advance if this wasn't the right forum to post this in.


thanks

if it is, i can't seem to find it.
