And if you do want integrated Bluetooth and FM traffic, Amazon.com has the 760 for $229.99, only $30 more than the 750 at Costco.
BTW, for anyone with a Gen2 Xterra, Nissan makes a really nice docking station for the Garmin 700-series units that replaces the center tray on the top of the dash. If you want to use the FM traffic receiver (or the MSN Direct receiver), though, you'll need to modify it a little.
