I have a 94 burb that I just bought to pull my boat, and the factory radio has to go, but I have no clue on how to install a radio. The setup and weird the radio is a like a medium size box, and is above the ac unit, and to the far right where a glove box would be to the bottom is the cassette and eq. Has anyone ever installed a aftermarket radio in one of these and if so how? Any pic would be helpful. Thanks
