i have a pioneer DEH-P840MP

and it's been working great for about 4 months no problems. it's been about -40 celcius lately and for some reason it just stopped working. it would turn on then turn off, half open and then close, the lights would flicker occasionally and then after about an hour of this it just died. anyone know whats up???
oh yeah, i checked all the fuses in the car already

thanks!

I think this happened to another guy on here and it was just dead. Hope not though, I have the same damn one.

I have the non-premier version. *crosses fingers*

Pray for the best, but if the fuses are ok and nothing is shot in the wiring (always double check) then you may want to get another HU, if it is only four months then it should still be under warranty.
