I'd think it would be easier to just switch to the III+ instead of the 
18, but since you asked:

I doubt you could get waypoints through the DB9, but you could probably 
make a 2.5mm cable such that the TX and ground go to the III+, and the 
RX and ground go to the 18.  The 700 would hear the 18 and talk to the 
III+.  Since you don't really need to talk to the 18 anyway, this could 
be your permanent cable, with a dangling DB9 waiting to plug into the 
III+ when you want to use it.  I haven't actually tried this, so be 
sure and let us know if it works. (:

I have a similar issue occasionally, in that I have a Trimble SV6 
(engine only, no display) in the truck, but once in a while I would 
like to use the MAP60 on the dash.  I just swap the 2.5mm cables on the 
D700, which isn't too much trouble with my rig's installation.
