Hi guys, I'm a new Aurion owner as well as new to this forum. From the topics that you guys discuss, many owners out there install that Auspack head unit that has all-in-1 functions. It looks really awesome and just wonder can any of you guys can direct me to a trustable service shop in Melbourne that has the head units and can fix it up for a reasonable price. The installation looks complicated, would this void my car warranty? What kinda of price am I looking at inclusive of installation? By the way seems like there are a few different kinds of similar head unit on ebay, which one is considered the best unit? (Auspack?) Thanks guys, really apprecitate your assistance!!
