I am looking to put an in dash nav unit and maybe some other monitors. Does anyone know how to remove the radio? Also my car does not have the pop up nav that come out the top of the dash but I have a speaker like grill where it would go, anyone know if that can be removed. I bought the car used and the pervious owner have serius radio but has removed only some of the wires, I need to see what was left behind. Last, does anyone know if there is a repair manual for the 06 v70?

Thanks for everyones input.
