Sometimes the NAV computers just crap out and cause battery drain as a result. Unfortunately it usually required NAV computer replacement. Maybe a good time to upgrade to a newer DVD NAV system.

Open the nav and remove the main circuit board
Observe the bottom rear corners of the board
Note the corrosion caused by water damage
Repair as required (requires specialised skills)

Note: you may also simply have a failled power circuit.

Sounds to me like the power supply in the nav has failled.

What made you reach the conclusion of "no failled power circuit" ?

All your symptoms point to failled power supply inside the nav...
