yes purchase a headphone jack to rca converter.... plug it into the headphone jack outlet of the MD player... purchase an RB-10 or RB-20... and plug it into the IP-Bus input on ur radio... then plug the rca's into it...
I believe the RB-10 will only allow you to use the RCA inputs, whereas the RB-20 will allow you to connect a CD-changer to the IP-bus at the same time as the RCA's(it lets you still be able to use the CD-changer).
