Check into DICE systems. They make iPod integration kits. Not sure if they work with regular audio outputs from a Curve, though.
I recommend this one:
It's great! That is if the curve has the proper audio out. Normal head phone jack will work. If n ot try to find an adapter that will work.
look for PIE GM12 aux adapter

If your bose has a cassete player this is a good option
if it does not then this helps
