Because 'Traffic Announcement' is logically most appropriate on the Settings > Navigation > Traffic Info Settings screen, I recommend removing such nav button from this Route > Guidance Settings menu and all other pages except for the Settings > Navigation > Traffic Info Settings screen.
NOTE: If Infiniti chooses to leave 'Traffic Announcement' on this screen, I suggest renaming it Traffic Announcements since one activates all verbal alerts with that selection, not just a solitary announcement. It's a subtle difference, but one that is grammatically more correct.
2) I recommend adding a nav button to this menu labeled Fewer Highway Announcements. When set to 'ON', this would cause the navigation system to only alert the driver to upcoming "turns" when he/she is exiting the current highway. It would also result in the navigation system displaying the distance to that highway exit, rather than to each intermediate merge where the driver has the opportunity to leave the highway along the way to the eventual exit. As an example, let's see how this setting would affect a route from Disneyland in Ahaheim, CA to Red Rock Canyon State Park in East Kern, CA:
 |
With setting OFF After merging onto I-5 North from S Harbor Blvd, the navigation system would tell the driver 11 times, "Keep to the left onto I-5 North" (at SR-91, I-605, I-710, SR-60, SR-10, SR-110, SR-2, SR-134, SR-118, and I-210) until finally merging onto SR-14. Then the nav system would tell the driver 2 times, "Keep to the left onto SR-14 North" (at SR-138 and SR-58) until finally exiting at Abbott Drive. During this trip, the "distance to next guide point" indication would only show the distance until the next highway to be passed (i.e. 4.4 miles to SR-91, then 8.5 miles to I-605, then 6.8 miles to I-710, then 2.2 miles to SR-60, etc.). With setting ON After merging onto I-5 North from S Harbor Blvd, the nav system would show 59 miles to the next guide point and wouldn't bother the driver again until he/she was close to merging onto SR-14. After merging onto SR-14, the nav system would show 93.4 miles to the next guide point and wouldn't bother the driver again until he/she was close to the Abbott Drive exit. |
NOTE: As an important aside regarding the voice announcements for the first example, instead of saying, "In # miles, keep to the left onto I-5 North", the nav system should say, "In # miles, continue left on I-5 North". That's a subtle but important linguistic difference because the former makes it sound like the driver is exiting one freeway and merging on to another, while the latter more accurately indicates that the driver is just going to stay on the current highway even though an exit is approaching for another. The latter is more of a 'just keep on going straight' warning rather than an unnecessary call to action.
3) The three settings on this page are duplicated on the current Settings > Navigation > Guidance Settings page, two of those settings (Guidance Voice and Guidance Volume) are duplicated again on the current Settings > Volume & Beeps page, while 'Traffic Announcement' is also duplicated on the Settings > Navigation > Traffic Information Settings screen. Redundant settings can be convenient, but in this case I think they're confusing and inefficient.
Since Guidance Voice and Guidance Volume wouldn't be active unless a route was set, I recommend making the above Route > Guidance Settings screen the primary location for those two nav buttons. So that those settings are still easily accessible, I suggest the Settings > Navigation > Guidance Settings page add a direct link to this screen rather than redundantly duplicating those two settings there.
