Dear atsutaka, Sorry for late reply. Unfortunately, DW does not support the ESR 2.5 24VDC. We only support the 12VDC. ---

Thank you for your response, Can you clarify if the Delphi ESR 2.5 12 VDC Radars will work with DW? Does the Continental ARS408 radar work with DW. We are using the Nvidia PX2 and were told from Autonomousstuff that the ESR 2.5 24VDC worked with this system so no we are back tracking to see what sensors actually work since we were steered in the wrong direction initially. ---
