Will the WAAS upgrade include vertical approach guidance? i.e. the
"improvised" GS on a step down approach.

Not to be the whiner of the group, especially over a great product, such as,
the 480...BUT...this reminds me of another feature sorely lacking in this
box. It offers no VFR vertical guidance as the x96's have. IOW...it won't
tell you when to start a decent at X feet per minute to arrive at Y feet
above the airport elevation, Z miles from the final destination. I know
that this is not needed in an IFR situation, but geez didn't they think the
480 would be flown by general aviation VFR occasionally?

I guess I'm disappointed because I've been wanting this unit for a while now
and always assumed that when I bought it, it would come with everything the
396 had plus the full IFR approaches, holding procedures and airways.
