Radio/Command and Telephone Not Working
 

I've no power to the command centre at all...battery was flat but I've checked 61 and 66 fuses as re fuse diagram but they are ok....help needed urgently as I've sold the car and the system was working fine then :confused:...PS I checked the fuse at the back of the system also and it is ok too

new command system need ouch i changed mine (used unit) from japan a new command will cost about 5k from the dealer

Got it up and going again..but now the radio shuts down after about 20 minutes ( this is with the car NOT started )...The digi clock then does not display on the dial. I have to remove the neg wire from the battery and leave for a minute and when reconnected.. all is well......until I turn on the radio and the process starts again.
