Touchscreen = undoubtedly Connect Premium. Also if the SatNav takes postcodes, equally its Connect Premium.
HDD isnt missing, its only activated when you insert a CD. It allows said CD to be ripped to the HDD as an MP3 and played back via the media system without the disc in future. Most find this is a pain and just get a USB stick and put MP3s on that, or connect an iPod. Oh also note, CD has to be a "proper" CD, not a CD of MP3s. It will play MP3 CDs I think but because they are not original songs, it wont copy them. It will only copy CDA or whatever the format is on production CDs.
You definately have Connect Premium though
