HI I have a Nissan patrol GU that I needed a reversing camera, gps satellite navigation and Bluetooth hands free talking function. I looked around the internet also on forum for a suitable company with a good reputation to supply / install the products.
around, I have found After calling ppa car audio ; they were able to assist me , were very knowledgeable and seemed to know what they were talking about.
I ended up purchasing Kenwood brand navigation unit which has all the bells and whistles that I was looking for including navigation, Bluetooth, reversing camera for behind my gu, digital radio, normal radio, dvd, connects to steering buttons on steering wheel etc.
Overall, I must admit I am satisfied with what I have received; 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. I am satisfied with the product and service . here is a link to the unit I purchased: http://www.ppacaraudio.com.au/index.php?route=product/category&path=60
