Fitted my RNS510 version P with a new can gateway version S last week and everything was working fine but didn't use the car over the weekend and on Monday the battery was completely flat so we jumped it and it was fine. Been fine since Monday but went to use it today and it's completely flat again do you think this is related to the can bus, unit or the firmware?
Any help or advice would be great as I thought everything should be working 100% without any battery drain.
Thanks
