Similar thing here, lots of very short journeys and had the I drive re-boot a couple of times, as well as satnav freeze.

I wasn't sure that you could connect a charger to the under bonnet charging point. Does't the circuit get cut off when the car goes into sleep mode after 15 minutes?

You can (if you haven't already) check your battery's voltage through the 'hidden menu', with engine off and engine running, to check it's charging okay from the altinator.
