The ATV25B had some running change that affected the DIN connectors of the Bluetooth Controllers.
Version 1 uses a 6-Pin Female DIN Connector without NFC functionality ( PN: RCU-D2-ATV25B-F6DIN)
Version 2 uses a 6-pin Male DIN Connector without NFC functionality ( PN: RCU-D2-ATV25B-M6DIN)
Version 3 uses a 6-Pin Male DIN Connector with a NFC functionality ( PN: RCU-U3-ATV25B-M6DIN-NFC)
ATV85B uses a 6-Pin Male DIN Connector but it is not interchangeable with the ATV25B Bluetooth Controllers.
