Our 2007 Executive head unit with DVD also has FM radio, but if my memory is correct, it does not have AM radio. Though the unit still works well, it would be nice to have a Blu-Ray unit with AM/FM and a nice user friendly display and interface, in a plug-n-play replacement that fits in the same cubby hole.
As I recall, one of the inconveniences with our 2007 Executive unit is that it does not remember my settings after 110V power is cut off. But that is asking a lot in any such unit, maybe requiring a serviceable memory battery. The same inconvenience applies to our 2007 26" Samsung TV. Every time I turn them on, they behave like they are brand new, like I just pulled them out of the box. That's life in an RV.
