Hornby have posted news on their website relating to the use of Hornby decoders with Gaugemaster Prodigy Advance consoles.
Those with first generation Gaugemaster Prodigy Advance consoles and using Hornby decoders should return their console to Gaugemaster for a firmware update. Following on from this the Hornby R8215 decoder will function correctly.
The Hornby R8215 decoder functions correctly with the more recently produced Prodigy Advance controllers.
Happy modelling
