Unfortunately, I don’t get the expensive paid OnCall remote control for the ERS heating in my V70 in Austria activated due to legal concerns. Is there someone here who knows how / where I come to retrofit a classic pre-heater with OnCall and CAN integration? The material is with approx. 6,700,- in the list (excl. installation). My dealer would give it to me due to the wrong order for 3,500,- and install it. Compared to 1250,- ex factory (incl. installation) however, this does not seem to me particularly favorable. Does anyone know a cheaper source? LG Rudi
