i see there is quite a big difference in the consoles from the lx and ex/si with navigation. say i were to buy the navi unit, would i have to buy a whole other dash piece or can i use the same one i have on my lx now?

sorry if this has been asked a bajillion times!

 

to input any aftermarket radio/navi
you will need the dash trim from a navigation civic

 

get the dx dash trim.. or an aftermarket trim kit..
