you are going to need the pac unit to be able to access the H700 as well - so just stick with that unit, it's a plug an play operation.
You don't need a 5M cable to get to the trunk btw, you can get a 4 m if need be, but beware of the cable you do choose. If it has a large connector on the end (like the high end Monster ones) it will not plug into the W200 easily. It will also block you from plugging in other optical accessories at the H700
Just something to keep in mind.
