Garmin RAT file Garmin ROU file

[philliplucky]

Are Garmin files RAT or ROU files ?? if so how do I convert them to Lowrance??
Garmin home port doesn't recognise them

I think they are adm but you can usually export in gpx (generic) to transfer to lowrance. Otherwise use gpsbabel to convert to usr

ADM,use GPSBABEL to convert as Lowrance uses difference versions depending on whether it is Hook series, Elite etc found that out the hard way when a mate went backwards from an Elite to Hook.
