Hey guys... Newbie here. I've had my F700BT for a little over a year now. I recently ran into the issue where the unit was going black after the splash screen. Occasionally I'd be able to hit the map button after a few minutes and the unit would spring to life but more often than not I wasn't getting anything. Life's a bitch when you have a destination programmed into the thing and you can't cancel it!
At any rate, Pioneer of course requests sending the unit in. I'm not going to do that. So I did a little searching and this is what I ended up doing...
