I've been trying to download the current set of updates since last night via wireless. I've tried loading all of the updates at once and individual updates. It chokes consistently half way through the Avaiation Databases. If I try the Cincinnati Sectional or any of hte WAC updates by themselves it chokes on that as well. In all cases I get a red error box reporting a download problem. All I've been able to successfully download via wireless is the TFRs and the CO Airports.
I'm running the online update via my PC now. However, if I were sitting in a pilots lounge trying to obtain a current sectional update via the wireless option prior to a flight, I would be pissed.
Suggested improvement: If doing a mass update and one file fails to download, move on to the next one. Either come back to the failed file later or issue an update summary at the end that reports "x number of updates failed, please try again".
