For a while now my command unit stopped working. Looked like it was a battery issue as mine went flat a few days ago. Tried to get the car moving so I connected some jumper cables to the terminals in the engine compartment and the unit powered on. Had both main and auxiliary batteries replaced at a workshop and now the command unit is not working again. Had a look at the fuses and pulled out the unit. Everything looks fine. I'm confused as heck at this point. Anyone experienced this issue before?
