just get a cheap pioneer HU from wal-mart...installation is easy and if ur THAT lazy...bring it to me (j/k)...im pretty sure ford used the standard AM/FM..AM/FM/Cass...AM/FM/CD and the "premium"...dont know if the mach came in a ranger but probaly not...also not sure of they used an in-dash changer...but go with an aftermarket, buy the wiring harness adaptor and mounting kit (if needed) and take 2 hrs to install...u get to sit on ur **** and basically do nothing (sound good enough for ya?)
