I believe the answer is no, but we need some more details on exactly what you are asking. The WiFi receiver is not an XM receiver, and SkyView does not support XM data at all. However, we do support free ADS-B data with a different receiver.
Also, there are often contractual requirements that prevent proprietary data, such as XM Weather, from being transmitted OUT of a device licensed to receive it, so it's unlikely that it's legal to "pass along" XM Weather data to SkyView.
