i just got my 20 gb unit couple of days ago. i am trying to install it in my 98 civic that has the factory radio and another slot by the cup holder where i have a factory cassette playter installed. i want to install it where the cassette player is but this guy at circuit city said that it can be done but i have to ditch my factory radio and install something with aux in and then install the empeg where the cassette player is. i know i can install empeg as the only head unit but i don't want to lose my radio and/or buy an amp and all the stuff. so how easy is it to do this where i can buy a cheap head unit w/ aux in and install both in my civic. i have opened the dash a little bit and found it a bit hard to open up anything more. i have installed stuff in my old sentra before so i am not really a newbie with this stuff. can anyone give direction or recommend someone/place in baltimore, maryland area where i can have this done or at least have it checked out. thanks.
