I recently added a new top head unit, mainly for CarPlay. But it keeps draining the battery. I recently bought a new battery about 2 weeks ago, as the original was on its way out anyway, but this one has also started to drain to, I have been through the settings, turned off sleep mode function, but I am at a loss as to why it’s still draining. Anyone have any ideas as to why?! And anyone know how to fix it.
