Let me know if it goes away with Hijack v34[12].

I installed Hijack v342, and the first time I put the player in the car it booted up in AC mode.

I don't know if this is significant, but when it boots in AC mode in the car, if I pull the player and reboot it always seems to come back up in AC mode. But if I leave it sitting overnight (possibly all I have to do is leave it until it goes out of standby mode?) it boots back up in DC mode.

Also, if it boots in AC mode, if I go into the HiJack menu to check and make sure that the AC/DC mode is indeed set to "Normal" (it definitely is!) and then press the left/right buttons to force reboot, it boots back up in DC mode.

As best I can tell, the serial connector and the tuner connector are not touching anything made of metal.
