The BR/RT wire on X18802 (pin #7) is a video earth from the nav unit in the trunk.

Is there a difference? E.g. is one a permenant live and one a switched live?

Neither - in this case "positive" refers to the id of a balanced signal - from the radio.
Power is on pin #7 of X18801 - red/white (RT/WS - Rot/Weiss). It's a switched power feed from fuse F75 in the trunk fuse panel.
The same fuse also feeds X18802 on pin #8 (RT/WS).
