Tilt the steering wheel low and grip the face plate that covers the
cluster and radio and pull it straight out. You kind of have to wiggle
it out so as not to scratch anything. The radio is now exposed. Some of
these just had a couple of locking tabs that need to depressed to
release the radio body or some had four screws in the front that you
have to remove. Then it just slides out where you have to depress the
locking connections and remove the antenna connection.
You may notice that there are 4 holes surrounding the radio faceplate just about big enough to stick an icepick or small nail into. This is for a radio removal tool -- but you could use some formed U shape coat hangers, or similar. 2 holes on the left and 2 holes on the right. Inserting metal pins into these 4 holes will unclip the radio from the dash.
