In the past having experienced the frustration of resetting all memory based presets in several cars after changing the battery and also the cars' software relearning of operating parameters, I've purchased an inexpensive item that claims to retain all memory settings while the battery is out of the car. It is a simple device that uses a 9 volt battery and plugs into the lighter socket allowing you to then remove the battery with no loss of battery power and memory (sorry no photo.) The Evoque's lighter sockets remain live with the ignition off. My next future battery removal will test this device. Has anyone experience with this item?
