Stereo questions...

I'm not hacking this dash all to pieces. As it is now, I'm going to have to cut it a little to get the Kenwood unit init, BUT the stock original face plate will still cover that up, so I won't have really hurt anything. I have a smart phone now, believe it or don't, but I am 1) not savvy enough to use it "like that" and 2) I want what I want and keepin music in a smart phone "AIN'T IT".
My music is stored in the phone, backed up on my laptop and on the cloud.
