General help needed with aftermarket H.U. / fuses

[x3me]

hi,
i've just tried to reconnect my pioneer avic witch was powered by an constant power. i've got an ignition feed from a cigarette lighter.
connected H.U. turned the car on and it turned on just for a split second, then off again...:bang: the weird thing that now i've got no lights inside, all the light cluster's are working as they used to, but it doesnt turn on
had a look into the fuses and it seems to be ok...
any ideas what it might be?
plz help

You might want to check the fuses again, cuz the interior light will be on the same fuse as the stereo so if both aint working thats proberly your problem.
