wow . . .. . I want one of these : (just a pity that our weather options in Europe are rubbish compared with the States)
Garmin have the GSR56 datalink weather receiver available NOW in Europe and this will give METARs, TAFs, aviation ground weather radar etc, very similar to the XM service in the US. The system covers all of Europe, unlike the Avidyne MLX770, which doesn't have Spanish radar. In addition to the weather service, the GSR56 also provides Iridium satcom voice calls and text messaging. The GSR can display on the G500/600 EFIS (and some G1000 systems such as the Beech 200 retrofit) as well as the GTN650/750 series.
