Ok, im getting a head unit and i have two questions

1. At crutchfield it as me for my make. It ask year, make, model, then it ask with or without mode button. What the heck is a mode button and do i have it?

2. What size head unit? It seems like a double deck size(I'm really not sure). Should I just trust crutchfields recomendations based on the make info?

 

thwey give you everything you need to install it so no worries just order w/e u want and you should get everything you need.... depending on how much u spend that is... i think its like $125 + and they include everything for install but idk... good luck!
