Battery was loosing most power after idle for 2 days. It occurred after the 6 CD player jammed. I could hear the player even after turning the ignition off. It was suggested to replace the navigation body control module. Cost estimate of $9,000 was prohibited with 12 year old car. It was suggested and I agreed to use a relay switch,. It would prevent using the fab and cause the clock/radio resets.
The other day the CD player was able to eject and the electrical noise stopped Is it possible to check the voltage with the CD Player problem solved?
