It does not. You need to go to the page that ask you if you want to sync all feeds. That will import them into the car. Its been a while since I've done it, but here is information from their website:
Destination Send-to-Vehicle enables you to search for destinations from a point of interest (POI) database accessed within the website. You can then send the information to your Infiniti’s navigation unit.
Enter search criteria in the “What to Search for” box
Enter search location (e.g., city and state) in the “Where to Search” box
After search results display, check the box to make your selection(s), then click “Send Destination Set”
On the Send Destination Set pop up, choose a folder from the dropdown box (or create a new folder) to label the category
Choose a feed from the dropdown box (or create a new feed) to name it (a feed is a collection of POIs) – Choosing an existing feed will replace all of the existing POIs in that feed
From inside your Infiniti:
Press the Info button
Select "Infiniti Connection" on your touch screen
Select "Sync all information feeds" on your touch screen
Select the folder
Select the destination name to show the route
I sent infinity a e-mail regarding this issue and got the following response.
Unfortunately, we do not have instructions for this as the feeds will start to drop off after a certain amount have been sent to the vehicle. The oldest feeds will delete first, and continue to do so in chronological order as you send new feeds to the vehicle.
