Ford Ls Rns Sat Nav Mp3 Cd Radio Problem

[Neil Oxley]

Focus Titanium - ls rns sat nav mp3 radio navigation unit not
working. it has twice powered off and powered on spontainiously without
requiring the code to be entered to re-start. whilst powered off the new
battery power was totally disapated. there was about 1 amp flowing. on
removal of the unit the current flow ceased. the power comsumption of
the unit has been checked whilst out of the car and it is effectively
zero (this is not definitive as the unit cannot be properly powered up
out of the car and the intermittent nature of the fault).

Can anyone offer any suggestions?
