Moin guys, just talked to my Volvo dealer about a remote control for the Volvo heater. Information; there is only the unidirectional remote control TP4 for the XC90 and not the model TP5 (bidirectional). It should only be available for the models V70/S60/S80. Has any of you drivers (=XC90 drivers) connected a bidirectional FB? So long Texan
