The current setup is temporary... I want to replace all the interior, so once I start getting my new parts I'll use the originals as guinea pigs to hack up and make sure my ideas will work properly.
Next thing to figure out is integration of my Creative Zen... essentially I want to have my zen dock in the car and be able to keep it charged and the AV signal go to the headunit. I have a few ideas, and will have to experiment and draw up some designs. Once I'm done it'll be so nice for road trips
