I would be willing to bet that Garmin shares a significant amount of
code between their panels and their handhelds, at least when it comes to
the 396. And, the Jepp data is the Jepp data. Sure, there is no
certification document with which handhelds must comply, but I just
don't think it's worth losing any sleep over, or even giving much though
to, for enroute navigation. I just don't care. In almost 10 years of
using various hand held GPS units in the airplane for enroute
navigation, I have never ended up in the wrong place. That's certainly
more than I can say for my ADF.
