I just flew from Florida to Denver, Ohio, back to Florida. Liked everything
on XM weather except the winds aloft info was far from correct. Estimate it
was significantly wrong 75 % of time (so far off it was of no value). Used
altitudes from 3,000 to 11,500 msl.

For what it is worth, I've been flying the 396 for a year now (I was one of
the first to get one) and I've been on the "$50" subscription ever since. I
have found the winds aloft data to be as accurate, and in most cases more
accurate than what Flight Service and Enroute Advisory Service will give
you, from all altitudes from surface to 16,000 feet (most of my flying tends
to be long cross country in excess of 500 miles one way between 4500-9500
feet).
The only problem I had (as had most all of the early purchasers) was that
the unit would not update as fast as it should sometimes...a downloaded
(free) patch from Garmin fixed that problem.
I heartedly endorse this unit...in my opinion it is the greatest single
piece of equipment ever developed...a great GPS, and a weather display that
is the next best thing to a weather radar, without the drag penalty or cost
(and if you have weather radar, it gives you the ultimate weather picture).

Forecasts have never been reliable and never will be, and that is
|
what those winds are, they are forecasts. I think the strength of
the XM weather is the observed stuff, just like in the rest of aviation.

You flew too low.

I know this is going to be like the "primer war".
Winds aloft forecast based on observations taken on the 20th at 8:00pm EDT
(0000Z). Forecast valid on the 21st at 8:00am EDT (1200Z), for use from
5:00am EDT (0900Z) to 2:00pm EDT (1800Z). Temperatures are negative above
24,000 feet.
In the last issue of IFR magazine they discussed this. Note the forecast is only valid at 1200Z. The rest is a WAG.
I do not think WX Weather makes its own independent forecast.

I have had my 396 almost a year and use it in the RV7 and the company Citation. Have not noticed any significant errors in winds. The best part for my use is the WX. Prefer it to the radar. My BIGGEST problem is the XM antenna is intermittent and appears to be in the plug. I can wiggle the wire and make it connect sometimes. Have used someone else's antenna and it works fine.I hope to get this resolved with Garmin at OSH. Anyone else with this problem?

Rich is right these are just FORECAST.
Why do you need a forcast when you are flying, you
have actually winds, use those.
