So I have an 8, 2004 model. And I find that my carputer dosnt work. Wont turn on at all. I've been looking for a diagram that shows me which fuse to check, but havnt had any luck. Anyone had this problem, or can stear me in the right direction?

 

What's a carputer?

 

Are you talking about a custom installed carputer or the factory installed navigation? The factory navigation is far from being a carputer.

 

Excuse my improper terminology. No its the factory navigation system. I think its fead from the room fuse. I found it was disconected on the back of the display unit. And I finaly got ahold of the guy I bought it from, and a dealership unplugged and told him it was the sourse of the draw that was apparently killing the battery after 3 hrs or so. Thats all I have so far. I've considered tracing the power wire and putting it on a relay to accesory side of ignition. But this would only work if I did the whole key on to accesory for 6 seconds before everytime I fire up the car, due to the nav system reading first voltage and not getting confused. II'm not doing anything with it till I know more though. I am curious as to how a short in that nav system could compleatly drain a battery in 3 hours though.
