Received my 2.1.1 update yesterday as well. In the details, simply lists 'Horn and Lights added' with some details but already had that on my app. Still not able to work with XM so using the Android app for my XM channels.
So for a little creativity, I have XM on another vehicle with the XM app, so just played it via my Android Audio. May keep it this way to save on a 2nd XM vehicle fee. BAM!
After the update, what is your SYNC 4 version? Mine lists "21146_PRODUCT", Revision: 145.
For my XM status, tried to remove and reseat a couple fuses for Audio & SYNC but no luck. Dealer hasn't seen this issue and recommended I drop it off for a couple of days. DAYS?!?! ?
Well called the FORD 800 number per their SiriusXM 360L site info...tried a module reset with holding Power & right arrow down for 5+ seconds. It reset but no change. Will try a Master reset soon.
UGH!!! Seems I'm a test case with XM having issues. Hope I don't have to perform a Master Reset but may try it soon. My XM is stuck on Channel 2 and not able to manually tune to 0 for a 'refresh'. It just displays 'SiriusXM Loading...' on my display. Had a online Chat with XM folks, but not...
I see the same after an update this week. Unfortunately my XM is now not working. My display lists 'SiriusXM Loading....', all my XM presets now list 'SDAR', stuck on Channel 2, and not able to manually tune channels, UGH! I've refreshed my radio a few times over the past few days but no luck.
