That's not true. You have been given (and are now passing on) bad information.
The Blackbird is pretty advanced. You can choose between shortest (distance) and quickest (time). It has nothing to do with "popular routes". You can also maximize freeway, minimize freeway, etc. The first Blackbird was a piece, but they've worked out the bugs. The biggest problem with the second gen Blackbird is the price.
The W205 is a great head unit to START a system, but you pretty much have to add everything separately. I have just about everything you can add to it, and it's great, but very expensive. The main reason I purchased it was to use it with the H701, and everything else came later. Unless you are really going crazy, you can probably get what you're looking for for less money and without getting so many different pieces.
