I just replaced a Pioneer in my boat for the meer fact that it is water resistant and has alot of flexiblity with outputs ect.... The manual for the stereo is another story, very poor explnations of controls functions,fortunately my friend owns a high end shop that helped me fine tune it and it performs great so far. Today however we noticed a little mold growing behind the flip down panel,u have to be careful not to rip the water barrier seal while cleaaning it. I just hope it holds up in a boat where fun is the rule, not being uptight about every little scratch ect... We shall see.
Seems to be good for the money.
