Wondering why I only see "Incoming Call" instead of the caller's phone number when I have an incoming call. Any ideas?

 

It's been a while back since I had my '05 but I could've sworn the number showed up on the information screen on the right gauge? I'm definitely getting my cars confused, but didn't the TL have an address book to put numbers in? I KNOW there's a way to change that...do you have Navigation?
