If you bought an SE version of the XR, why would you even consider anything besides the BMW Nav V? Your bike comes with GPS prep, pretty damn nifty integration of the GPS controls on that left bar wheel. From there you have a ton of control over what your Sat Nav will display including many engine parameters, Music being played and of course, a plethora of navigation options. It is not a cheap option but is based on the Garmin 590 LM, I also own this as well as the Sat Nav V, both are excellent GPS units but having the BMW integration into the spin dial makes it a major bonus and a no brainer in my book.
