hi all im having trouble with my mk111 monitor sat nav on a 2002 e46

the stereo shuts down with ignition but the monitor dosnt even if to monitor off option it still drains the battery the problem started when i lost sound on stereo an sat nav then read some where that there is a safety cut out and you have to remove fuses 7,41 then replace too get sound back which i done and volla got my sound back but now the monitor dosnt switch of with ignition any ideas cos its a pain in the but too keep removing the fuses each night


one other thing the clock dosnt hold time on monitor or on trip computer
