One of the most irritating oversights on the T5.1 which gives away its commercial van underpinnings is the fact that the 12V outlet in the cup holder does not switch off when the ignition switches off. I have to physically unplug the GPS charger to stop it from draining the battery. Irritating.
I decided to tap 12V from one driving light fuse circuit (LHS driving light I think) in the center fuse box (underneath the cup holder) by using a blown fuse as a tap, fitting a replacement fuse holder to hold the original fuse and tap 12V from the driving light circuit.

The new 12V outlet was fitted above the accelerator pedal next to the diagnostic plug.
It works well initially (GPS reacts to 12V Ignition ON and turns on, but after a few minutes the GPS keeps on indicating that it has lost power supply. The GPS battery eventually dies...
There's no problem with the GPS itself - it works 100% when working off the 12V plug in the cup holder.
What can it be? The fuse spec for the driving light circuit is 5A. I fitted a 15A fuse to drive the 12V outlet for the GPS. Does the GPS not receive enough power? Or does the daylight circuit switch off and on whilst driving? Perhaps the circuit senses an incorrect load, but then I have had no faults showing on the dash?
Can anyone shed light on the matter?
If the driving light circuit is the wrong one to tap 12V from, which one is safe? This is a 2011 T5 2l 75Kw Caravelle.
