The Force AC/DC power mode feature (Hijack) is working fine as far as I know.

Which brings up a question, Mark...

I was hoping to use the "if tuner=x then force DC" feature for a little while to help alleviate some of the nasty effects of the AC sensor switch problem but I couldn't get it to work for me. It always seemed to come up in AC power mode.

I only tried two tuner numbers, 0 and 1. What tuner number is the default number if I've assembled Patrick's kit according to his instructions without fitting any jumpers to change the tuner number?

Is there a way I can check the tuner number from the front panel? I don't have a way to hook up a serial console or ethernet when it's car docked.
