Ended up going with the bi-directional with a spare remote.  Looking through the manual, I'm not seeing anything about a heated seat option.  All the other options (run-time, temp etc) I found and set via the MFT, have it set to memory for the temp, but still cant get the heated seats to engage. 
  
Am I missing something?  Accessories guy at the dealer said several times that this option WOULD work, but I cant seem to figure it out.  Thought I'd check here first before calling the dealer.
