Nokia :: 5230 / Dialler & Bluetooth Errors

My wife has just got a new 5230, and we have come across a couple of issues which I wondered if anyone had answers to.First, when opening the "dialer" option during a call (so you can respond to "press 1 for....." questions), the "keypad" does not display the letters associated with each number (i.e. "ABC" on key 2, etc.). Is there any way of modifying settings to show the letters as well?Second, when using the phone in our new Fiesta, the phone book is displayed in the car as "last name, first name". The phone displays as "first name, last name" which is what we want. Using my phone in the same car (Nokia 3109), the car displays "first name, last name". I've got round the problem by putting each of the phone book entries into the Last name field only, but this obviously isn't ideal. Again, any ideas? I asked this question to the Nokia help desk, and got a generic "this is how you connect to the car using blue tooth" answer, which was no help at all!
