I have a current draw thats killing my battery. After doing some diag, I found that when I remove the "room" fuse, the draw goes away. So I looked up the wiring diagram and started disconnecting the navigation system till the draw went away. I started with the navigation module, and worked my way into the dash, leaving the connectors dissconnected. When I got to the Nav screen, the draw went away. So I am pretty sure the screen is the issue. Just wanted to see if anybody has heard of this? Wanted some reassurance, as the screen is $3600.00.

There was a thread several years ago about this very problem. As I recall, the problem was with the hard drive not shutting down. Do a search and you may find the thread. I will see if I can find it.

EDIT: Here is the relevant thread: https://www.rx8club.com/showthread.p...=battery+drain

Quote from that thread:
"After they tried it for two weeks they agreed and applied to Mazda techies. The result was that the NAV Hard Disc drive wasn't properly shutting down after the car was turned off. Mazda replaced the NAV unit and it seems to be OK now. I fetched it from them on the 15th and eft it in my garage until today the 28th. 13 days and it started up just fine with no indication of a low battery."

Thanks for the link. I'll retest and make sure it is not the hard drive. I want to make sure. I am pretty sure its the screen, because i had everything else disconnected, but I will double check.
