Two problems with all in one units. First, if one function fails, and

someone come out with some new feature, you can't just replace that
unit, it's all or nothing.

All true, but on a smaller boat (and some larger), there is just not
room enough for a full suite of electronics. If you buy quality such
as Furuno there should be minimal down time.
