interesting.

I saw on manual that there's also a zero-power consumption installation if you are willing to route cables

The Zero Current Drain installation can be done by installing the yellow fuse tap in a switched fuse location in the engine
bay or instrument panel fuse blocks. For example, fuse F17 in the instrument panel fuse block. If you install the yellow
fuse tap in this location and route a wire back to the controller module in the rear luggage compartment, then when you
switch off the ignition, power will be interrupted to the controller avoiding any power drain.

Yes, that's the best long term solution, I'll route it through to that in the summer.
