When I got mine, I would only buy a new Trail with KDSS. When I called up Autoland, the "Auto Broker" company for my Credit Union, I told him what I wanted, what features, colors, etc. He called me back an hour later and said there are currently non in the region with what I want but there are two that are on a boat in transit. He got my credit card number just in case the receiving dealer wanted a deposit from me, which in the end they didn't and They finally delivered it to me on that Tuesday.
Definitively call multiple dealers, check online sites as well. Finding one without KDSS and Nav shouldn't be as difficult as the dealer is making it,,, although the local dealer I first talked to about getting a Trail Edition with KDSS finally found one after 2 months of me owning mine already.
