Buying advice.

Can someone please recommend a budget / mid range CD Auto-changer system.

FM tuner and remote CD unit.

There is one main criteria:-

The unit is to be fitted in a sail boat. Also on the boat is a navigation
computer, which can also play DVD's. I require the Tuner / CD unit to have
an analogue aux in, so that the output from the PC sound card may be
connected, enabling the DVD soundtrack (2ch) to be played through the
system.

TIA
