Bought my wife a 2010 TE loaded last fall for $38,000-this was the invoice according to the dealer and the web sites I saw. MSRP for this one was $42,000. I don't know where you live but a dealer in Durango, Co said he sells a lot of 4R's and has a local company install aftermarket nav system for $800-$1400. You probably could find someone to install yours.
