Sirius disappeared
 

I have a 2013 GP2 - I drive it rarely, and listen to the radio even more so, so can't pinpoint exactly when this happened... but Sirius has disappeared from the list of possible inputs in my MINI Boost head unit.

I had cancelled the subscription a couple of years ago, and hadn't thought about it since, but on going to select it this past weekend, discovered it was not there. The list of inputs I have available is FM / CD / Aux / Ipod. I thought I was going crazy for a couple of days... then I found the email (and Radio ESN) confirming my Sirius subscription, so I know I definitely had it!

The only thing I've done to the car since the time Sirius was working is install a dash cam and radar detector (involving trying to find an acceptable fuse to tap). I also had a MSFW refit for cruise control which involved an ECU code, but Sirius was working after this....

I'm putting in an Integral Audio Soundstage at the moment and would like to have Sirius working (yes, I know Sirius is compressed garbage).

Any ideas why I lost my Sirius, and how I can get it back???
