That is great news. Now it would be even better if it worked with a Garmin Area 510 or a Garmin panel mount.
I was going to bite the bullet and pay XM $35/mos to get weather. I got so far as calling to place the order - I was almost there until the guy said the activation fee was $75. I'd like to think I'm not cheap but I had to ask - Why a $75 activation fee for weather when the activation fee for a music subscription is just $15. Is one more complicated to activate than the other??? After a pregnant pause I went on - "...well, as long as I'm asking questions, how many millions of dollars per year to pay Howard Stern to be obnoxious and obscene? I'm asking because you only seem to charge $15.99/mos to support him but to simply rebroadcast a subset of free data you want me to $35/month and if I want all of your free data, it's going to cost me $99/month. Can you help me understand your pricing schedule in a way that doesn't make me think you're gouging me because I own a plane to support the folks who can't support Stern?"
Three phone call referrals and two e-mails later, XM has not only avoided answering my questions, they won't even acknowledge them as questions, except to say, "we hope you're satisfied with our answers." Of course, there was nothing that resemble an answer or even a diplomatic rephrasing of my polite but direct question.
$800 to avoid XM - you bet! ADSB on an iPad (I own one and use ForeFlight), I'm not so sure. My guess is Garmin will be last to ADS-B dance.
