First check the fuses under the hood, As far as the antenna goes, go to the trunk and pull off the left side that protects the left rear quarter panel and 1st check for the ground wire, it that is connected take a lead tester and check for current coming to the unit, if you have current you could have a stuck antenna, then take I think a 13mm wrench and unscrew the antenna from the top and turn the radio off then on and while it is turning tug on the unscrewed antenna, if the motor is working the antenna will come out, then you need to just change the mast by leaving the radio on and pushing in the new antenna and turn the radio off and feed the mast in and screw on the cap, if no power and motor then you need to change out the entire unit. As far as the cruise control issue, first check for the fuse, then locate on the brake the release switch as that could be faulty or disconnected, then pull of the air cleaner and check the linkage, if that does not help, I would then obtain a cruise control amp, this is located under the dash just above the driver's left knee, pull off the plastic protecter, plug in your new unit and test drive, if that works, pull the dash off and swap out the unit.
Please post your results here.
