This unit is my longtime favorite unit as it is an am/fm, cassette/CD and allows you to jump around between modes without discs or cassettes having to be re-inserted. My 2000 Super Duty has one also and this a definite upgrade to the old cassette only unit in a 1999 Ranger. The unit was a long-time coming due to a last minute QC concern at the shipper and a very slow fed-ex (8 days cross-country), but it looks and performs (so far) like new. So -- worth the wait.
