Problem is that I upgraded my Cmap for larger area and now it will not work
on my GPS Humminbird NP25.
It works on a friends Navman 5500i strangely and is ok when checked by the
supplier.
His older equivalent chip works on my Humminbird but not my equivalent but
newer Cmap which is meant to be
identical.

Any body aware of why this should happen ???

While not quite the same as you, I know somebody who had a new/old
Cmap problem and it had to do with the interface. Did the supplier
check it against a NP25 by any chance?
