This particular device is for traffic only. ADS-B in the US is slightly different as it encompasses the FIS-B (WX) and TIS-B (traffic) feeds. There are additional ADS-B units coming to the market. We are currently working with APPAREO, maker of the Stratus. We will know more in the coming weeks and after we can get some development specs. I know there are other devices coming this summer in the $600 range. Beware of these micro USB unit under a few hundred dollars as the don't support WX.
