I got the 550 as the TAWS is higher resolutionthan the 500 (same as the 496) and also it has the capability to display traffic info on it, which I *believe* the 500 didn't. The 550 will be backup to a 430W.
That's really useful - one question: how much better/worse are the terrain mapping on the 550 versus the 500? That seems to be the big difference between the two - from my perspective at-least, and the question of whether the extra resolution is really worth the extra £480?
