Hi, I've been waiting a long time to get a pioneer system and was going to get an avic f900bt but now a new system seems to have come out (x910bt) which is in my price range in the future. I have a scion tc and know that it's easy to install these gps systems in that vehicle and because I am not very auto savy I wanted to know people's opinons about a self installation. Even more I want would be someone to make a Step by Step in depth DIY either with pictures or a video would be better if someone can of their installation of one of the previously stated pioneer gps or something similar in a scion tc. Thanks. And again I am not very smart with cars so I would appriciate a really in depth DIY if anyone has time to make one. Thanks Again.
