So on the reverse camera, I guess you don't get the different parking options either, ie parallel or perpendicular parking and the different lines on each.
Is your Galaxy Mini up to date with the latest Android. Updates? Also, check in the phonebook or people options where the contacts are being stored. Are they all from your Google account, or from the phone, SIM, or elsewhere. Are all the options enabled in the phonebook options on the phone, so all the contacts displayed? When you go to the car and check the contacts options, how many does it show it has transferred? Mine is showing 2002 of 2500.
I still get random contacts which appear in the phone and not in the car. This is with various Android phones and I can't determine why. I've also found if you have a contact with more than 4 listed numbers, the car duplicates the contact name and spreads the numbers over both.
