Hi guys, it is writing a lot in the forum on this issue,but there are still things that are unclear, at least to me. I want to install these three things in the title of the topic in the following priority: 1.Listen and watching files from USB source 2.Rear camera 3.DVB-T tuner,it's not important,but I saw this model (Ampire DVBT53),which combines tuner and playing files from usb. About the rear camera i don't have any idea how to connect it. What I know is that there must to have a multimedia adapter (and how can connect more than one unit via one adapter) and another black box for watching during movement (which can be substituted with VIN Hack,is that correct?). Please give a cheaper options and web sites in Europe from where i can buy it. There are a lot of kind of cameras and DVB-T in Chinese web sites also,is it good idea to buy from there? Some wiring diagrams will be also useful! My Audi is A4 B6 Avant October'2004 with RNS-E 0650 soft, CD-changer, bluetooth, multi wheel, аll factory-installed. After one month i will change the laser optic,the current stopped reading. I have a VAG-COM and am familiar to use it. Thanks in advance! Regards!
