all electrics gone suddenly on car, started with radio now nothing works!,HELP!!

Either your battery is completely flat or your alternator has gone south either way, some voltage checks would prove useful.

As above, battery every time

they need to be a good battery on these, any working inside the car and ignition on, will soon flatten the battery real quick

if the battery low, it puts modules in fault, need to get the battery on charge, ideally over night

cheers
