MAXICOSI or Römersitz Desaster in the V70 – Square Desaster

Hello Volvo colleagues, this morning we wanted to pick up our twins in the Khs. I bought 2 new Roman seats. Then, at 9:10 am my blood pressure on 200. The Roman seats do not fit on the rear seats, if the front seat is set to the rear and down, the seatrest is set “normal”. So I have to make the seat about 10 cm forward and then I, with 1.92 m height, have the problem that I have to operate the steering wheel between the knees, if I could still pack in between. What do I do!? First I thought, ok, on the middle 3 point belt. What do I have to recognize? The belt is about 10 cm too short, meaning I can’t get into the belt lock. So that’s not possible. I thought that further, then I put the 2nd seat on the passenger seat, then my wife or I can sit on the rear left. Nor can I see, because it doesn’t have an airbag off switch. Even more annoying, the newly ordered one is on the factory belt and the seller could not have ordered the “extra” middle seat. But I could not have bought the option for the factory.
