We need to be clear here. There are TWO different traffic sources; The on-map ClearChannel and Text To Speech Aha. The Aha will work on any of the older units once the software update is released. The ClearChannel is ONLY on the new Z130 and X930.
Gotcha...integrated ClearChannel traffic solution is ONLY on new units. Thanks! Not clear if that means BOTH the new Z AND the new X will have it, or just the new Z. The website they're starting to load makes it look like only the new Z has the integrated traffic tuner, but I'm sure you'll verify this.
Also, when you play with the new units, be sure to test the extent to which each different type of replacement traffic solution (integrated ClearChannel on the new Z vs. the TTS Aha) integrates with the navigation, yes? e.g, speed bubbles on route? colored traffic speed lines next to roads on screen? re-routing? traffic event browsing? Etc...
We'll have more instructions for you later! They'll come in the form of a self-destructing DVD LOL
