Since my problem is the same as the original poster's ,
I'll give full details...

Car : Volvo V40 1.8i 2000
Empeg : Mark 2 #080000144
Amp : Caliber 80.5

My empeg is connected to :

permanent power : 12V
ignition sense : 12V if in state I or II, 0V if in state 0
lights sense : Varying between 3V and 10V
phone mute : Connected to Nokia 7110 in Nokia Carkit
Amp remote on : 12V if empeg is powered on

When I insert the empeg in it's sled when ignition is off (state 0) the player will not start up. When changing to state I the player boots, the amp get's powered (I hear a light pop), then the empeg goes into standby. Turning the knob or pushing any button will make it active again and the amp is powered again (light pop). When switching off the ignition (state 0) the empeg completely shuts down and a hard Thump is heard.... Note, I didn't start the car, I just switched from state 0 to 1 and back again...
I measured all voltage with a simple multimeter, but couldn't find any voltage changes during statechange...
