I have an '86 GN that came with the middle of the road AM/FM/Cassette deck without equalizer. I recently scored another one of those and a stock radio with equalizer. My stock '86 stereo has the power button integrated into the volume switch, while the two '87 radios have a separate power button. Does your '87 radio have a separate power button, or is it like my '86? Just want to see the spare radios I have are correct for an '87 Regal.
