Hi folks, I am looking for an after market head unit (GPS, DVD, bluetooth, USB, iphone, [DVB-T, reversing camera] etc.) and I am a bit confused. I have read this forum and elswhere and understand there are sone cheap Chinese units that fall short of the more expensive brand name units. I was hoping to find something in between for my 2009 Aurion, maybe around $600-$700. It looks like there are a couple of new-ish units available on the market and I was wondering if anyone has any expereince or knowledge about them. The first is a unit that trades under a few different 'Tunez' names on ebay and their own web site. http://www.ebay.com.au/itm/8-Toyota-Aurion-Camry-Car-DVD-GPS-Player-Navi-DVB-T-TV-Head-Unit-Stereo-Tunez-/281124931893 http://www.tunezmart.com/shop/products/111-Toyota/3-8-Toyota-CamryAurion-car-DVD-player-with-GPS-and-DVBT/ The second unit is an android device which I think has been mentioned here by others. Both have 8" screens and similar features. http://www.ebay.com.au/itm/8-Android-Toyota-Camry-Aurion-WIFI-GPS-IPOD-Car-DVD-Reversing-Camera-/261209301960 A local car audio dealer is pushing me to buy this Opal unit for around $1500: http://aus-audio.com.au/products/opal/optungps Like I mentioned, I don;t know which way to turn for quality, function and value so I would love to hear from anyone who has any advice, particularly about the 'Tunez' units. Thanks a lot, Steve
