New 09' civic 4dr lx owner ,I'm looking to upgrade my factory radio to the oem navigation and xm unit.Other than the radio/nav screen and xm module what will I need to buy to add this in? Does this car come with the same harness as a vehicle with navigation already? Will plugs already be in place or do I need another harness.I have yet to take anything apart to see whats there..I have previously owned a 99 Acura tl w/nav then the 04 tl w/nav....So this is something I'm used to in a car..Must have!! Any help is appreciated......
