Towing operation: PDC and 2nd indicator in the cockpit at the V70 ?

Moinsen Bande, once asked for a short time, because I was a bit irritated. I always had a 2nd flasher indicator in the V70 II with attached trailer which flashed with it, thus always the certainty everything correctly connected. Now I also equipped the successor with a Westfalia so far the Jaeger electric set… 1. no 2nd flasher indicator 2. the stupid PDC beeps itself to a wolf as soon as the reverse is in it. Questions thus: to 1: does the really no 2nd anzeigen? to 2: has the still someone m it nem Jaegersatz? and a 3: Did someone with VIDA turn on the PDC so that it is switched off on ignition and is only used manually if necessary?
