I stand corrected- however, the quality is much better than FM broadcast,
and with no commercials.

The decision regarding the GDL 69 comes down to convenience and the need to
have a lot of loose wires, notebook computers, etc in the cockpit, even with
bluetooth.

The GDL 69, although not perfect, integrates well with my 530, particularly
in combination with the stormscope. It is excellent for a long range view
if you are going around an extended line of storms, but would not be
especially good for navigating through a line of scattered storms. In this
scenario, on board radar is a better choice, along with the stormscope.

The XM radio is an added bonus, particularly on those long cross country
trips.
