Bose Sounddock and Ipod - Able to use for Ceremony??

[KCDawn]

My Fiance and I decided we are going to invest in the portable Bose Sounddock (About $400) to use for our wedding in Mexico.  Between the welcome bonfire, our ceremony and reception, if we paid to rent the resort's sound equipment to use with our Ipod it would cost more than the Sounddock.  At least this way, we spend the money and still have a great system to use later.  It has since occurred to me that the Sounddock isn't compatible with a microphone.  How does this work for the ceremony???  Will we still have to rent the resort equipment for the ceremony so everyone can hear the officiant?  I'd hate to do both but I would feel awful if our friends and family spent so much money and time to come to our Mexican wedding and not be able to hear anything.  We are expecting about 35 guests and we're getting married at the resort's Gazebo, not on the beach.  Any suggestions???  Anyone do this yet??
