I have a GDL 69 and so far have not had any problems in solid IMC, snow, or
even icing conditions. The display of Nexrad weather is invaluable, while
the requests for textual metars is a little cumbersome. I also got the
option of satellite radio, and it is nice on the long cross countries.

Garmin dropped the ball regarding the satellite radio, since there is no way
to adjust the channel or volume without the addition of an ugly external
box, which does not display the channel. However, the weather stuff works as
advertised.
