2005/270 - I am not sure if I have the std. set up or not- I have a sony am/fm cd, a separate cd changer and also an amp of some sort. I have helm remote as well as swim plat form remote. When boat was purchased a year ago, the swim plat form was in op but was good with that. Now, neither of the remotes work and while the radio does still work, I can't adjust the volume. This type has the removable head and I cleaned the contacts. I can live with the no remotes but the volume is a deal breaker, any ideas?
