I have recently installed one of these. http://www.ppacaraudio.com.au/index.php?route=product/category&path=60 Very impressed with it, it has all the bells and whistles including navigation, Bluetooth, reversing camera for behind my car, connects to a reversing camera for my caravan , digital radio, normal radio, dvd, connects to steering buttons on steering wheel etc, everything works like a well-oiled clock. I arranged to get the unit installed 1 day after calling the team at PPA, their professional came to my work, installed the whole lot in under 4 hours and left. However all good and very pleased with the unit I am happy with the result.
