I used to have the identical boat except in blue. My headunit was mounted in the glove box and used a hard wired remote, which is the only way to go remote wise.
Using a device to control volume and a couple of amps driving the speakers all you would need is an MP3 player. Instead of sinking the money into a headunit put it into amplifiers. Better sound and you are not paying for a unit you will not use.
BTW there is not enough room under the drivers side dash to mount a headunit, you would knock your knee on it. Right below the circuit breakers is a good place to mount a volume control or a remote.
Time to kick that wake up alot!
