Hi,
Very new to the whole world of HM7000 and Bluetooth decoders, and still in the process of deciding whether to go down the HM7000 route or conventional DCC.
Just bought a Bachmann Class 20/3 that has a 22 pin socket, which the Hornby R7322 HM7000-21TXS: Bluetooth® & DCC Sound Decoder (21-pin) wont fit without some sort of convertor. Is my new loco incompatible with the HM7000 system or is there a work around.
TIA
John
