DVD Player Audio to OEM Bose Head Unit

I have a Nissan Armada with the Bose system and navigation package.  I am putting in a Blaupunkt ME3 DVD player.  I'm attaching the schematic diagram from the service manual for the OEM DVD system.  My question is can I take the RCA left and right audio from the DVD and connect it to wires 34, 35, 36, and 37? and get the system to work like OEM?  I don't know what the FES stands for.  Also if this is possible do I take a RCA cable and cut off two ends and I assume its like a coax cable and there will be the ground outside of the center positive, and then just splice into the appropriate wire?  I ended up just patching into the AUX connection which works but I would like it to function close to OEM.  Thirdly, if that is not possible, I have only tapped the aux wires and just left it unpluged from the dash jack. Can I plug it back into the dash jack and if needed plug a different source into the jack through the dash...assuming I am not using the DVD player???????

still didn't work...anyway the wires are labled FES LH input (-), FES LH input (+), FES RH input (-), FES RH input (+), There is also a FES enable and a audio on wire that connects between the factory dvd and head units. Is there anything I should connect to these wire as well? 

I decided to avoid the hassle and tapped into the aux jack behind the dash.  Volume was low so I ordered http://www.discountcarstereo.com/detail.asp?product_ID=LD-1
