put car in park with brake on, pry off the black bezel. it comes right off
, I used a paint scrapper because it's thin and won't scratch the grey
plastic around it. remove the 4black screws holding the rdaio and the
useless rectangular box under it. they come out together, unplug unit by
pushing clip on top of the connector and antenna plug.
if you are putting a new radio in, you will need and adapter.
here is a source (lotsofcables@aol.com) he cahrges about $4.00 plus
shipping and will throw in a neat set of piezo speakers to boot. plug
adapter in harness and into back of new radio.  you jave to drill 2 new
mount holes on side of new radio to mount. but it's pretty easy. becareful
of the height of the new unit. the bezels on kenwood units are higher then
the old radio, so you have to get an adapter which willmake the the little
storege box 1/4 inch flatter.
if you need a source, contact me. I just did the job in my daughters 2000
sportage. plus I put a roof rack on for $97 that came out great, after I
got the courage to drill the holles in the roof of the car.
