Just got around to turning on my Solo (GDI-IRA500) but too late it would seem.
The presets were no longer stored and no connection to the server. There is a recorded Grace Digital blurb on all presets saying I should go to "gracedigital.com/pages/update" for further options, but of course nothing there. There were still a few stations under "My Stuff" which I have since assigned to presets.
Worse still, my trusty Avox Indio petite won't turn on at all. It shows the regular "off" screen and the connected internet symbol but does not respond to either the remote or button on the set. Can't tell if it's simply bricked or no longer responds to commands due to some firmware glitch caused by shutdown.
What a dissappointment they have turned out to be. Would have gotten rid of these radios anyway due to the shut-down, but it is indeed a right bit of cheek to simply discontinue service. So am wondering if the shutdown itself somehow deletes the presets and other features??
@Dogmatix: interested in these radios? You can have them for the price of shipping (€4 or 5).
