This is about the weird behavior of our 2013 R56, standard radio and single CD, no NAV. About a month ago, Sirius quit, it is paid and registered with Sirius. The .SAT icon also disappeared on the "Mode" menu. Switched to an other key fob, and all was well for a couple of weeks, then Sirius disappeared again. Put in another used unit, and the same thing happened. After much experimenting, discovered that you can reset the unit (power button held down for 30 seconds) with no fob inserted and Sirius re-appears. Also, it works (mostly) with one of our fobs. Some times this fob causes a "Sirius failure" and then no Sirius, no SAT icon. The other fob doesn't work at all, you have Sirius working, insert that fob, and no Sirius. Remove fob, reset unit, Sirius returns.

Our MINI service folks (not a dealer, local shop) did diagnostics on the original unit and said the radio was bad, they got the Sirius to work with the diagnostic tool, but it didn't want to talk to the radio.

After spending hours looking for answers on Internet, my vivid imagination thinks it could be low batteries in the fobs, both original. My other suspect is a replaced battery about 3 months ago,, from the same shop, and it was registered with the car's computer. Other suspects include antenna, crazy wiring, Sun spots, and witchcraft. Any ideas would be appreciated. Thanks in advance.
