OK, I had my Mk 2 (#25) installed this afternoon in my Miata.

The first time I powered off the car, while playing a tune, the unit powered off (well, the screen went blank) about a second or so after the ignition was turned off. This seemed to make sense, give or take.

The second time I powered off the car, I had a tune paused. This time, the unit did NOT shut itself down, but instead I had to remove it from the chassis to power it off. My initial thoughts were "Hmmm, maybe I mis-remembered the first time's events and they actually wired the chassis live off the battery instead of the ignition?" except that replacing the unit did NOT turn it back on (until I turned the key).

Is there a bug in the ignition-wire-voltage-detection code such that it doesn't recognize loss of power if its paused?
