I was planning to buy a used Radio Head Unit to replace it from EBay but do you know if I have to have it program by a dealer or just plug and play ? Also my head unit doesn't have a Nav button on the unit can I replace it with one that has a Nav button then the wires plug in will be different in the back or it just has one extra ( Nav plug left out ).
I would like to add a back up camera to my car is there anyway I could do it ?

thank you again

 

I cannot confirm if the dealer would need to program it; I would guess that you can just plug and play though. As far as the backup camera goes, you can likely wire it into the new unit and assign it a button. Hope this helps a bit.
