Hi,

My name is J Brown, and I recently started having trouble with my newly purchased 2000 DTS (150K miles). The Nav System goes blank, I lose the radio, control of the windows, door locks, gas gauge, temp gauge and the ignition won't turn to the off position. I've pulled the Nav fuse (#15 in rear panel) out a couple times to allow it to reset. But by my third trip of the day the car goes right back to doing the same thing. Then I get the security light stuck on and a service air bag message. I've been told it's a bad BCM, and I've been told its a broken wire in the ignition. Please help me before I spend a fortune trying to fix this thing!!!!

Thanks,
