In viewing the 2006 STS Navigation System, I see a marked difference in appearance of the screen. The map detail is much easier to see as the colors are more vivid. Also, in daylight the screen does not seem to wash out from glare like the 2005 XLR. Is this something that can be upgraded in the 2005 XLR Nav System? If it is a software issue, can a new prom be inserted to update the system?
